Beam Stoppers
The Beam Stoppers are mechanical safety devices which are integrated into the FAIR Personal Access System (PAS). In case of any (beam) failure they will safeguarding personnel working in the areas NE55 (High-Energy Cave) and NE57 (Low-Energy Cave) by intercepting and absorbing the beam by means of massive tungsten blocks. The beam stoppers are located at appropriate positions further upstream in the Super-FRS.
The design phase of the two Beam Stoppers has been concluded by our provider Axilon AG (Germany). The corresponding Final Design Review (FDR) was approved in November 2022.
The Super-FRS beam stoppers are in house since December 2023.
