  1. beam intercepting devices for LINAC 4 Status Report, ENTM 02/11/2010

  2. Overview • Beam stoppers for source/LEBT and forLinac4 transfer line • Chopper line collimator • Beam dumps for the movable bench (C. Maglioni) • 50-100 MeV measurements bench dump • Beam dumps for LBE/LBS lines and LBS slit • Head, tail, H0/H- internal dumps for the PSB injection region (R. Chamizo) • Linac4 main dump (R. Chamizo) O. Aberle, EN-STI, Linac4 Beam Coordination Committee - Meeting 20

  3. LINAC 4 layout O. Aberle, EN-STI, Linac4 Beam Coordination Committee - Meeting 20

  4. LINAC 4 layout • Beam stoppers for source/LEBT • 50-100 MeV measurements bench dump • Beam dumps for the movable bench (C. Maglioni) • Linac4 main dump (R. Chamizo) • Chopper line collimator O. Aberle, EN-STI, Linac4 Beam Coordination Committee - Meeting 20

  5. Beam stoppers for source/LEBT • Beam parameters LINAC4 Project Document No. L4-T-ES-0001 EDMS Document No. 1057463 Racetrackflanges are housing the beamstopper. Twoflangesfacingeachother (180°) O. Aberle, EN-STI, Linac4 Beam Coordination Committee - Meeting 20

  6. Beam stoppers for source/LEBT • Design finished • Production started • Ready by the end of the year • One unit withIris to produce a pencil beam O. Aberle, EN-STI, Linac4 Beam Coordination Committee - Meeting 20

  7. Chopper line collimator (3MeV) • Produced and installed O. Aberle, EN-STI, Linac4 Beam Coordination Committee - Meeting 20

  8. Beam stopper forLinac4 transfer line • Slit LBS • Slits LBE • Fast beam stopper • Sieve (removed) • Beam stopper O. Aberle, EN-STI, Linac4 Beam Coordination Committee - Meeting 20

  9. Beam stopper forLinac4 transfer line • Intension to reuse the existing stopper tank (layout dimensions and functionality) • Simulations for the material to be done • Cooling to be foreseen (additional piping) O. Aberle, EN-STI, Linac4 Beam Coordination Committee - Meeting 20

  10. Beam dumps for LBE/LBS lines and LBS slit LINAC4 Project Document No. L4-B-ES-0001 v.1.0 EDMS Document No. 1056611  v.1.0 • SPECIFICATIONS FOR BEAM DUMPS IN LINAC4 DUMP LINE, LBE AND LBS LINES • F. Regis will work on that • LBE dump • LBS dump, feasibility study for integration done • LBS slit • Start with the 3-12 MeV slit design • Go towards a stripping foil with a dedicated dump (below the spectro-meter magnet? • Have a thick slit,absorb most, but less clean beam? O. Aberle, EN-STI, Linac4 Beam Coordination Committee - Meeting 20

  11. 50-100 MeV measurements bench dump LINAC4 Project Document No. L4-T-EP-0004 v.0.2 EDMS Document No. 1094599 v.0.2 • USER SPECIFICATIONS FOR LINAC4 COMMISSIONING DUMP AT 50 AND 100 MEV • To be treated together with the main dump (160MeV) • Two solutions: • A “movable“ version for 50 and 100 MeV • Use a stationary dump for 160 MeV O. Aberle, EN-STI, Linac4 Beam Coordination Committee - Meeting 20

  12. 50-100 MeV measurements bench dump 100 MeV 50 MeV O. Aberle, EN-STI, Linac4 Beam Coordination Committee - Meeting 20

  13. Planning • Chopper collimator done • Source stopper ready in January 2011 • Dumps for the measurement bench April 2011 • 50/100 MeV dump – 160 MeV main dump for the end of 2012 • LBE/LBS and slit from 2013 onwards • TL beam stopper for 2014 • Head and tail /H0/H- for 2014 O. Aberle, EN-STI, Linac4 Beam Coordination Committee - Meeting 20

  14. EVM / Planning O. Aberle, EN-STI, Linac4 Beam Coordination Committee - Meeting 20

  15. EVM / Planning • EVM to be created for: • 3-12 MeV measurement bench • LBE/LBS dumps and LBS slit • And the 50/100 MeV dump DRAFT O. Aberle, EN-STI, Linac4 Beam Coordination Committee - Meeting 20
