Among several working groups formed in the framework of Physics Beyond Colliders study, launched at CERN in September 2016, there is one investigating some specific fixed-target experiment proposals. Of particular interest is the study of high-density unpolarized or polarized gas target to be installed upstream the LHCb detector using storage cells located around the beam to enhance the target density. This work studies the impact of the interactions of 7 TeV proton beams with such gas targets on the LHC machine in terms of particle losses. The overall compatibility with the planned high-intensity program of the LHC is also discussed. A calculation is also performed of the minimum acceptable radius for such a storage cell in order to ensure safe operational conditions.

Abstract

Among several working groups formed in the framework of Physics Beyond Colliders study, launched at CERN in September 2016, there is one investigating some specific fixed-target experiment proposals. Of particular interest is the study of high-density unpolarized or polarized gas target to be installed upstream the LHCb detector using storage cells located around the beam to enhance the target density. This work studies the impact of the interactions of 7 TeV proton beams with such gas targets on the LHC machine in terms of particle losses. The overall compatibility with the planned high-intensity program of the LHC is also discussed. A calculation is also performed of the minimum acceptable radius for such a storage cell in order to ensure safe operational conditions.
