  1. Status and Plans of3 MeV Test Stand

  2. The 3 MeV Test Stand is installed in the PS South Hall extension (building 152)

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

  5. Activities at the Test Stand in 2010MEBT line completed With 3rdbuncher cavity

  6. Activities at the Test Stand in 2010RF installation progress 2nd buncher amplifier installed

  7. Activities at the Test Stand in 2010PIMS prototype tested

  8. Activities at the Test Stand in 2010PIMS prototype tested Table courtesy of R. Wegner Nominal gradient of 4 MV/m reached with 700 kW

  9. Activities related to the Test Stand in 2010Movable Test Bench Design of Test Bench completed; Design of all components completed; Fabrication started for all components; Start of assembly in May.

  10. Activities related to the Test Stand in 2010Movable Test Bench • 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) From: G. Bellodi - User Specification for Linac4 Test Bench Diagnostics

  11. Activities related to the Test Stand in 2010RFQ fabrication and measurement

  12. Activities related to the Test Stand in 2010RFQ fabrication and measurement Module 1 completely brazed, final machining still to be performed:

  13. Activities related to the Test Stand in 2010RFQ fabrication and measurement Module 3 passed 1st brazing, now is being machined for 2nd brazing.

  14. Activities related to the Test Stand in 2010RFQ fabrication and measurement Planning to RFQ completion

  15. Activities at the Test Stand in 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 2013.
