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

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

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

Beam stopper for Linac4 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) 9 O. Aberle, EN-STI, Linac4 Beam Coordination Committee - Meeting 20

Beam dumps for LBE/LBS lines and LBS slit  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? 10 O. Aberle, EN-STI, Linac4 Beam Coordination Committee - Meeting 20 LINAC4 Project Document No. L4-B-ES-0001 v.1.0 EDMS Document No v.1.0

MeV measurements bench dump  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 11 O. Aberle, EN-STI, Linac4 Beam Coordination Committee - Meeting 20 LINAC4 Project Document No. L4-T-EP-0004 v.0.2 EDMS Document No v.0.2
