Abstract
Among several working groups formed in the framework of the Physics Beyond Colliders study, launched at CERN in September 2016, there is one investigating specific fixed- target experiment proposals. Of particular interest is the study of high-density unpolarized or polarized gas targets to be installed in the LHC, upstream of the LHCb detector, using storage cells 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.
Highlights
In the framework of the Physics Beyond Collider study program, which investigates new experimental possibilities exploiting the CERN accelerator facilities [1, 2], a working group is studying proposals of fixed-target experiments at the Large Hadron Collider (LHC) [3]
For the case of the elastic beam-target interactions, the H and the Xe cases are presented in Figs. 1 and 2 for Beam 1
The power lost per meter is plotted as a function of the longitudinal coordinate s, starting from the interaction point (IP) 1
Summary
In the framework of the Physics Beyond Collider study program, which investigates new experimental possibilities exploiting the CERN accelerator facilities [1, 2], a working group is studying proposals of fixed-target experiments at the Large Hadron Collider (LHC) [3]. The scattering rate of 7 TeV protons on a target with a large areal density might limit the machine availability, since too high beam losses could cause the superconducting magnets to quench.
