1. Introduction

Current Landscape The landscape for accelerator activities in the UK associated with neutron production has recently been assessed as part of the STFC Accelerator Strategic Review. This landscape is currently dominated by operation of the UK’s internationally competitive ISIS spallation neutron and muon facility at STFC’s Rutherford Appleton Laboratory and management and delivery of the UK’s in-kind contributions to the accelerators for the new European Spallation Source (ESS) under construction in Lund, Sweden.

Figure 1.1: Schematic layout of the ISIS Facility.

• ISIS accelerator science and technology activities facilitate day-to-day facility operation and

the programme of equipment renewal and upgrades required to keep the present ISIS accelerators running optimally and sustainably for the lifetime of the facility.

Figure 1.2: ESS High Beta Cavity, Linac Warm Unit and RF Distribution.

• The UK is making significant in-kind contributions to the ESS accelerators (ASTeC, Technology

Department and Huddersfield University) and is committed to a delivery programme for High Beta Cavities, Linac Warm Units and RF Distribution with timescales of end-2020, mid-2019 and end-2018 respectively.

Other related accelerator activities currently being pursued include:

• The Front End Test Stand (FETS), which is a generic proton accelerator R&D programme (ISIS, ASTeC, JAI, Imperial College London, University College London, Huddersfield University, Warwick University and ESS Bilbao) based on a 3 MeV RFQ and ‘ideal’ chopping system which could enable a significant increase in the flux of neutrons available for the neutron user community on ISIS and at similar facilities worldwide.

Figure 1.3: Schematic layout of FETS.

• Ion source development plasma studies, which fill a vital scientific knowledge gap for ISIS

and the international ion source plasma community, and are applicable to newly funded industrial collaborations (UK Space Agency, Added Value Solutions, Surrey Satellite Technology Ltd and the University of Southampton) on space thrusters.

• The Intense Beam EXperiment (IBEX) (ASTeC, ISIS, JAI, Hiroshima University), which has recently been built and commissioned at STFC Rutherford Appleton Laboratory to study the intense beam dynamics of a non-neutral plasma confined in an electrodynamic trap, which is equivalent to that in an accelerator focusing channel.

Future Horizon The recent report from the STFC Advisory Panel – Neutron & Muon Science and Facilities, A Strategic Review and Future Vision has established that central to all the options for the future horizon is the need to maintain the ISIS facility. In light of the significant changes anticipated by the ESFRI Physical Sciences and Engineering Strategy Working Group over the coming years as reactor-based sources close and ESS comes on line, there should be further detailed evaluation of the UK’s neutron needs in the mid-2020s. In readiness for this, at the start of 2016 a new ISIS-II feasibility study was launched in order to refocus on facility upgrades, with the intention of designing a major ISIS facility replacement or upgrade which would be complementary to ESS and provide enhanced neutron capacity in Europe beyond 2030. An ISIS-II Working Group was set up consisting of ISIS experts on accelerators, targets, neutronics, instrument science, detectors and engineering, in acknowledgement of the reality that any upgrade must be envisaged as a facility upgrade, not simply an accelerator upgrade. The working group was charged with looking at ‘short-pulse’ (< ~1 µs proton

pulse) options for a) a new stand-alone facility, b) a facility upgrade which reuses as much existing ISIS infrastructure as possible and c) compact neutron sources.

4

a) Stand-Alone Facility Assuming a green field site, full funding and two target stations from day one, the working group was unanimous that the most attractive option would be something similar to what SNS will look like after the proposed Second Target Station (STS) upgrade:

• 1.3 GeV proton beam at ~2.5 MW after Proton Power Upgrade (PPU). • First Target Station (FTS) at 50 pps (nominal frame length 16.7 ms), ~2 MW. • STS at 10 pps (nominal frame length 100 ms) , ~0.5 MW.

However, 40 pps (nominal frame length 20 ms) was felt to be better optimised for ISIS-II, and we would expect to add a muon facility at the end of the linac and/or before the higher repetition rate neutron target station. Working group recommendations regarding a stand-alone facility are:

1. Keep accelerator design on ‘back burner’ as most of the issues and design choices

are the same as those for ‘re-use of ISIS infrastructure’ scenarios.

2. Keep a watching brief on SNS FTS mercury target performance post PPU and STS

‘rotating wheel’ target development.

b) Re-use of ISIS Infrastructure

The working group found that:

• It should be possible to upgrade ISIS TS-2 (still at 10 pps) to ~0.25 MW with a plate

target similar to that proposed for the TS-1 upgrade which is planned to go ahead in ~2020. All flight lines would remain the same.

• A new TS-3 at 40 pps (eventually replacing TS-1) with a compact TRAM could operate effectively as a high resolution target station and complement an upgraded TS-2. If the nominal 1 MW proves to be too much power for a TRAM fully optimised for useful neutron output we could operate at lower frequency or reduced proton pulse intensity – we should design for operability rather than raw power.

• 1.2 GeV is the maximum beam energy that would allow re-use of the majority of the components in the present extracted proton beam lines (EPB1 and EPB2).

• It should be possible to fit a suitable 1.2 GeV accelerator running at ~1.2 MW in the

present synchrotron hall, based on a rapid cycling synchrotron, an accumulator ring or an FFAG.

• A staged approach should allow us to keep the ISIS science programme running as much as possible during ISIS-II build and minimises beam off time to any one target.

• The overall energy use, efficiency and environmental impact of the facility will be of very high importance.

• Highly optimised muon production should be possible at ~550 MeV by extracting a beam from part way along the linac.

The proposed accelerator specification is 1.2 GeV, ~1.25 MW, 50 Hz (but flexible frequency may present some advantages) with a < ~1 µs pulse train.

Working group recommendations regarding re-use of ISIS infrastructure are:

5

1. Keep development of RCS, accumulator ring and FFAG based designs active to the point where we can make a well informed decision on which option to pursue based on technical merit and lifetime cost.

2. The FFAG option will require R&D, with the initial proposal being the development of a prototype magnet (and later an RF system). If this is successful then we will aim to incorporate these as part of a small FFAG on the end of FETS in order to explore the beam dynamics fully.

3. Ensure that the upgrade is optimised for neutron production, but with careful consideration of muon production as well.

4. Pursue an appropriate development programme for a compact TRAM for TS-3, including definition of suitable figures of merit for moderator output.

5. Continue to reserve the space on the RAL site for a new linac, TS-3 and possibly a new muon target/instrument building.

6. Continue to explore staged upgrade scenarios in order to minimise cost and downtime at each stage, feeding this information into the technical decision making process.

c) Compact Neutron Sources

Compact neutron sources produce neutrons either through low energy (~10 MeV) protons

or deuterons incident on a light metal (Li, Be) target, or electrons on a heavy metal target (the Harwell Linac used uranium). For protons and deuterons the lower energy compared to spallation reduces activation and the need for shielding, but the neutron production process is less efficient so the performance is limited. For electrons the accelerator is much cheaper, but neutron production is even less efficient and higher activity waste still needs to be dealt with. The ultimate performance for a compact source based on protons/deuterons might be comparable to a medium flux reactor (e.g. Opal in Australia), though able to support a smaller number of instruments (6-7?) and still requiring significant development. However, the particular attraction of a compact source is that it would be affordable by a single country (<€300M?), whereas a new spallation source (>€500M) would almost certainly need to be an international collaboration.

Pulse compression to produce a ‘short pulse’ proton or deuteron compact accelerator-driven neutron source (CANS) is impracticable. Hence current ‘short-pulse’ CANS are typically driven by electron linacs, but these produce relatively low neutron fluxes. Laser driven sources (being developed at the Central Laser Facility at RAL and elsewhere) produce short pulses, but currently repetition rates are very low and the quality of the neutron pulses is nowhere near good enough to do useful science.

Working group recommendations on compact neutron sources are:

1. If ISIS has serious ambitions to become involved in the development of compact accelerator-driven neutron sources a small working group should be set up to investigate current worldwide capability and demand in order to determine how best to participate. Attendance at the next UCANS meeting and other relevant conferences and workshops should be ensured at an appropriate level.

2. Keep a watching brief on developments in laser driven neutron production in case of anything game-changing.

Other UK accelerator activities are expected to contribute directly to ISIS-II development:

Figure 1.4: PIP-II HB650 cryomodule.

• SRF cavity fabrication, preparation and testing for ESS by ASTeC at Daresbury Laboratory,

building on ASTeC expertise, industrial contacts and collaboration with CEA, INFN and DESY, development of the ESS RF distribution system at Huddersfield University and discussion of the UK contribution to PIP-II at Fermilab are all intended to maintain continuity of UK capability on the timescale of a UK facility such as ISIS-II being built.

• FETS will be used by ISIS for further accelerator R&D and is eventually intended to be the injector for a small-scale FFAG test ring as part of ISIS-II R&D.

• H– ion source R&D at ISIS is important as many new and existing facilities (including ISIS-II) are looking for improved H– source performance.

Figure 1.5: Optics in IBEX (left) emulating optics in the Fermilab integrable optics based iRCS.

• IBEX will address issues which will help to design better optimised high intensity rings for

ISIS-II. • Involvement in international studies of integrable optics would be linked to current IBEX

work and may expose interesting alternative possibilities for ISIS-II designs. The roadmap set out herein aims to work towards ISIS-II, incorporate the recommendations of the working group and integrate related UK accelerator activities while at the same time promoting involvement with ESS and maintaining ISIS operations and sustainability. This is intended as a sensible, achievable vision for UK neutron provision over the next 20 years, in line with the findings of the STFC Advisory Panel.

2. Roadmap Production Overview of Methodology The first stage of roadmap production involved the development of a Gantt chart incorporating all the tasks that would be required to realise the recommendations from the ISIS-II feasibility study (excluding compact neutron sources). Tasks were assigned at a suitable level of detail to allow each individual task to be fully resource loaded, using resource categories identified as important to ISIS-II:

• Accelerator Physics • Mechanical Engineering • Mechanical Technical • Electrical/Electronics Engineering • Electrical/Electronics Technical • RF Engineering • Neutron/Muon Science • Neutronics • Civil Engineering and Architecture • Project Management • Other (for instance project administration, procurement and legal services, etc.)

Integration of this resource loading across the entire activity gives an indication of how many FTEs in each category will be required and produces estimates of in-year and cumulative spend as shown in figure 2.1.

Figure 2.1: Resource FTE and spend estimates for ISIS-II.

8

In all of these resource estimates:

• FTEs are per year and the cost of these FTEs is not included in in-year spends. • In-year spends are for the sum of capital and resource. • No attempt has been made to apply inflation to any of these indicative figures.

This methodology was then applied to all the other UK accelerator activities which are expected to contribute directly to ISIS-II development, in order to produce the integrated Gantt chart and resource graphs presented in Appendix A, which represent the overall ISIS-II roadmap as it currently stands. ISIS-II As can be seen in figure 2.1, this activity can be readily split into three distinct phases:

1) Feasibility, design studies and R&D (2017-2027). In general resource levels for this activity are within the envelope of the ISIS facility budget. However, in the period 2023-2025 requirements for mechanical engineering towards FFAG design and target, moderator and shielding feasibility studies become larger than ISIS can provide. This issue could be addressed by increased (and earlier) involvement of the Target Studies Group in Technology Department, university engineering departments and contract effort. The main requirement for additional funding beyond that available from the ISIS facility budget is associated with building a small-scale FFAG test ring (~£10M) during the period 2021-2024.

2) Integrated facility technical design (2027-2031). Following the decision on exactly what should be built a largely new team of ~150 FTE will be required to produce a full ‘shovel-ready’ design. This will require significant recruitment in all key technical areas. It should be noted that for phases 2) and 3) indicative FTEs and costs now reflect design and build of the whole facility rather than just accelerators and targets.

3) ISIS-II construction (2031-2040). Indicative FTEs reflect the effort currently involved in ESS construction, which is on a similar scale. For simplicity the breakdown in effort of various types has been taken as constant throughout the build – the reality would obviously be somewhat different. The cumulative cost of the project has been given as a round figure of ~£1B (excluding FTEs), but this is only intended as a very early indication of the actual cost.

Related UK Accelerator Activities ISIS Operations and Sustainability FTEs and in-year spends include figures for both accelerator and target activities. For business as usual ~135 FTE (120 FTE accelerator, 15 FTE target) and ~£9M per year (£8M accelerator, £1M target) is required. Increased resource in the period 2017-2020 is associated with the TS-1 Project, on completion of which ISIS target engineering and neutronics effort will become available for target, moderator and shielding feasibility studies for ISIS-II. All of this activity is covered by the ISIS facility budget. FETS In general resource levels for the continuation of this activity are within the envelope of the ISIS facility budget. However, interim usage for any hardware intensive accelerator R&D during the

9

period 2018-2020 would require additional funding from outside ISIS. After 2023 the intention is that FETS becomes the injector for a small-scale FFAG test ring as part of ISIS-II activity. Ion Source Development Resource levels for this activity are within the envelope of the ISIS facility budget, including the cost of development of an RF volume source in the period 2020-2023. IBEX Resource levels for this activity are within the envelope of the ISIS facility budget, including provision for a new configuration and diagnostics in the period 2019-2021. ESS The combined High Beta Cavity, Linac Warm Unit and RF Distribution accelerator delivery programme for ESS equates to 75 FTE and almost £42M of hardware costs, with delivery timescales of end 2020, mid 2019 and end 2018 respectively. No estimate of any ongoing contribution to ESS accelerator operations has been included. PIP-II at Fermilab Resourcing levels for the delivery of four integrated Superconducting RF cryomodules have been determined based on existing resourcing provision of SRF cavity procurement, manufacture and testing of cavities for ESS and also by extrapolation of the resources anticipated for completion of the pre-series crab cavity cryomodule integration for HL-LHC, both of which are expected to conclude by the end of 2020. The total scale of this project, which includes demonstration of SRF cavity fabrication capability with UK industry, is £14.6M hardware costs and 40 FTE of manpower resource over a 4 year programme. Integrable Optics

Resource levels for this activity, which is likely to be ongoing for a number of years, are within the

envelope of the ISIS facility budget.

Next Steps

The ISIS Management Committee hopes to gain the endorsement of the ISIS Facility Board for this

roadmap as a sensible way forward and intends to organise an external review by accelerator

experts to scrutinise the fine detail before embarking on the design studies and R&D for ISIS-II.
