1 C. Rossi – L4 Project Meeting 3 March 2011 Status and Plans of 3 MeV Test Stand

2 C. Rossi – L4 Project Meeting 3 March 2011 The 3 MeV Test Stand is installed in the PS South Hall extension (building 152)

3 C. Rossi – L4 Project Meeting 3 March 2011 Activities at the Test Stand in 2010 Source Operation Impossible to operate the ion source with H - at 45 kV extraction voltage Characterize the source for p extraction at 45 kV to allow RFQ and partial MEBT commissioning

4 C. Rossi – L4 Project Meeting 3 March 2011 Activities at the Test Stand in 2010 Source Results with protons The energy spread of the beam is not larger than 400 eV (50 eV per mm) => ± 200 eV => ± 0.4 % Pictures from O. Midttun’s presentation Slit 1 mm Sol 600 A

5 C. Rossi – L4 Project Meeting 3 March 2011 Activities at the Test Stand in 2010 MEBT line completed With 3 rd buncher cavity

6 C. Rossi – L4 Project Meeting 3 March 2011 Activities at the Test Stand in 2010 RF installation progress 2nd buncher amplifier installed

7 C. Rossi – L4 Project Meeting 3 March 2011 Activities at the Test Stand in 2010 PIMS prototype tested

Wegner

9 C. Rossi – L4 Project Meeting 3 March 2011 Activities related to the Test Stand in 2010 Movable Test Bench Design of Test Bench completed; Design of all components completed; Fabrication started for all components; Start of assembly in May.

10 C. Rossi – L4 Project Meeting 3 March 2011 Characterize the beam properties at 3 MeV: At the RFQ exit in the Linac4 Test Stand (late 2011 and beginning of 2012) At the chopper line output in the Linac4 Test Stand (during 2012) At the chopper line output in the Linac4 Tunnel (early 2013) Characterize the beam properties at 12 MeV: At the DTL tank1 output in the Linac4 Tunnel (first half 2013) Transverse planeLongitudinal plane  Beam profiles  Beam emittances  Beam position  Transverse halo  Transmission  Average beam energy  Energy spread  Bunch shape profile  Chopping efficiency (time resolved and integrated) From: G. Bellodi - User Specification for Linac4 Test Bench Diagnostics Activities related to the Test Stand in 2010 Movable Test Bench

11 C. Rossi – L4 Project Meeting 3 March 2011 Activities related to the Test Stand in 2010 RFQ fabrication and measurement

12 C. Rossi – L4 Project Meeting 3 March 2011 Module 1 completely brazed, final machining still to be performed: Activities related to the Test Stand in 2010 RFQ fabrication and measurement

13 C. Rossi – L4 Project Meeting 3 March 2011 Module 3 passed 1 st brazing, now is being machined for 2 nd brazing. Activities related to the Test Stand in 2010 RFQ fabrication and measurement

14 C. Rossi – L4 Project Meeting 3 March 2011 Planning to RFQ completion Activities related to the Test Stand in 2010 RFQ fabrication and measurement RF measurement stepweek T2 after assembly14-15 (2/04) T2 after 1 st brazing19-20 (9/05) T3 after 2 nd brazing19-20 (9/05) T2 after 2 nd brazing29-30 (18/07) RFQ assembly35-36 (1/09) Fittings (tuners, power coupler, end plates)tbd RFQ completely assembledas from 44 (31/10)

15 C. Rossi – L4 Project Meeting 3 March 2011 Continue measurements and development of the ion source; Complete the infrastructure for the RFQ and Movable Test Bench installation (cabling, cooling); Perform the interlock system installation; Assemble the Movable Test Bench; Complete equipment installation (buncher amplifier(s), LLRF equipment, beam diagnostics, power supplies); Equip the control room; Perform the RFQ final tuning; Perform the RFQ RF commissioning. The Test Stand equipment will be moved to Linac4 at the beginning of Activities at the Test Stand in 2011
