Rough S2 Schedule

PhaseCompletion date Description

0 2005TTF/FLASH, not final cavity design, type 3 cryomodule, not full gradient, has beam

0.5 2008 Extra tests at TTF/FLASH with same type cryomodules as phase 0

1 20081 cryomodule, not final cavity design, type 3 cryomodule (and/or) STF type cryomodule, not full gradient, no beam

1.1 2009

1 RF unit, not all final cavity design, not all type 4 cryomodules, not full gradient, beam not needed for tests, but should be built so it and the LLRF are debugged for the next step

1.2 20101 RF unit (replacing cryomodules of phase 1.1), final cavity design, full gradient, type 4 cryomodules, with beam

1.3 20111 RF unit (replacing cryomodules of phase 1.1), final cavity design, full gradient, type DFM cryomodules, with beam

1.4 2011Tunnel mockup above ground. 1 RF unit perhaps built with parts taken from earlier tests. Includes RTML and e+ transport, no beam

2 2013N RF units at one site (of the final ILC?) as a system test of final designs from multiple manufacturers, no beam

3 2013 XFEL

NML plans

• The NML is being constructed to address primarily the S2 R&D list– However, our plans go beyond S2. We would like to include

elements of S4 R&D tasks (crab-cavities), diagnostics development, personnel training, and accelerator R&D.

– The NML facility is staged (1 CM, 2 CMs etc); when complete, it would include 1 (or 2) rf units running ILC-like beam at 5 Hz.

• The S2 schedule of having phase 1.3 complete at NML in 2011 is quite challenging– Only early stages of NML (up to 2 CMs) are well planned– 3 CMs (1 rf unit) requires building an extension tunnel and a

new cryo-plant– The progress is resource limited, thus the schedule has to

stretch to accommodate the scope

Outline of our plans

• Cryomodule delivery– 1st (Type 3+) cryomodule is planned to be delivered in

fall, 2007– 2nd (Type 3+) CM – summer 2008– 3rd (ILC Type 4) CM – Mid FY09– Replace all three CMs with ILC Type 4+ in FY2010

• The NML facility will start as a Cryomodule Test Stand in FY07-08

• FY08: add beam; start civil construction of the building extension

• Convert to an ILC RF Unit beam test facility in FY11

NML Schedule (Phase-1)

• Phase - 1 (FY07 thru early FY08)– Prepare Facility for Testing of Capture Cavity II (CCII) and 1st

Cryomodule (CM1) without Beam• Building Infrastructure (AC Power, Water, Air, Mechanical)

• Electrical Infrastructure (Racks, Trays, Cables)

• Build Cave to Test these Devices (~ 3/4 of Full Cave)

• RF Systems (3MW for CM and 300kW for CCII)

• Cryogenic System (1st Refrigerator, Feed Can, Feed Cap, End Cap, Distribution)

• Control Room

• LLRF, Controls, Safety Systems, Instrumentation (non-beam)

– Move CCII from Meson Detector Building (MDB) to NML• Cool-down and Power Testing

NML Schedule (Phase-2 & 3)

• Phase - 2 (FY08)– Testing of 1st and 2nd Cryomodule without Beam, Prepare Facility for

Beam• Receive, Install, Power, Cool-down 1st Cryomodule• Install New Gun and Relocate Injector to NML• Extend Cave• Install Beam Lines and Dumps• Install Additional RF Systems needed for CCI and Gun• Receive, Install, Power, Cool-down 2nd Cryomodule• Begin Building Extension needed for Phase-3

• Phase - 3 (FY09)– Testing of Full RF Unit with Beam

• Complete Building Extension• Begin Testing with Beam• Install 3rd Cryomodule• Upgrade Cryomodule RF system to 10 MW

Two CMs with beam

The existing building is perfect for testing two cryomodules with ILC-like beam. The building can be extended to fit 3 cryomodules.

Building extension

• Construct a new building ~50m away from NML. Connect by a tunnel when schedule allows. Move loading dock.

• ILC-like tunnel, space for 3 more cryomodules• Room for a new cryo-plant

New Cryo Plant

• Temporary cryo system (being installed now):

• New Cryo plant– Must be flexible to allow a wide range of heat loads,

including 5-Hz operation– Must meet specifics of the ILC operating temperature

levels of 2.0 K, 5 K, and 40-80 K– Long lead time

• Requires a 15m x 25m building; the plan is to combine it with the NML extension.

• Engineering studies complete, have a quotation.
