Update on ESS John Womersley, Director General UK Neutron and Muon Science and User Meeting 2019

Scientific and technological innovation is essential

• global challenges of energy, climate, environment, healthcare

• economic and societal challenges of stalled productivity and long term wage stagnation

First a quick reminder why we are here

Materials and molecules

Where are the atoms and what do they do?

New materials, new drugs, new processes, new energy technologies

How a spallation source works

proton accelerator target

moderator

sample

instrument

“spallation” is the process that releases neutrons from the target nuclei

5

Superconducting Proton Accelerator

Neutron Production Target

Experiments

Some numbers

1843 M€ construction cost, 47.5% from 🇸🇪 🇩🇰

5 MW world’s most powerful particle accelerator 2MW at start of operation

15 Instruments in construction budget

Aim for > order of magnitude increase in sensitivity of experiments

800 experiments per year

2023 first science for users

Current ESS temporary offices

Permanent Office Campus 2021

Lund Tramway Depot under construction

Data Management and Software Centre COBIS, Copenhagen University North Campus

Provide world leading scientific software and scientific computing support for neutron scattering at ESS

Scientific Software

ESS experiment control system, Data acquisition, Data correction software, visualization, and software to model and analyze experimental data sets.

Data center operations

Store and catalogue ESS datasets, provide ESS users remote access to their data, computing for live data correction, and analysis software during and after experiments.

User support

Support ESS users with data treatment and analysis.

26

• Good environmental building standards (BREEAM)

• Green construction site

• Purchase all electrical power from renewable sources

• Waste heat recovery into district heating system

And of course the research done at ESS will have a major impact on the energy sector

Sustainability is a core value of ESS
