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.
