The proton beam window for csns

WebbThe proton beam window (PBW) is one of the key devices of China Spallation Neutron Source (CSNS). When the beam power of CSNS upgrades from 100kw to 500kw (CSNSIII), the present single-double layer structure of PBW cannot meet the demands. The PBW will be changed to other structure. Webbfirst 20-m beam line of the Back-n is shared with the last section of the proton beam line – RTBT (Ring to Target Beam Transport). A proton beam window (PBW) in A5083 aluminum alloy of 2 mm in thickness is located at 1.9 m from the target which separates the vacuum tube of the proton beam line and the target vessel.
