On the Possibility of Having Roman Pots around IP8 in Run 4 and Beyond

Abstract

Proton trajectories along LHC beam 1 (clockwise direction) in the vicinity of the LHCb Interaction Point (IP8) for the most recent LHC Run 4 optics (HLLHC1.5) were presented. On this basis, three possible locations of forward proton detectors were identified: 150, 180 and 430 m from IP8. For these locations geometric acceptances were estimated. For the proton relative energy loss, $\xi$, these limits are $0.05<\xi \lesssim 0.1$, $0.025<\xi \lesssim 0.1$ and $0.003<\xi <0.013$, respectively. The influence of boost of the central system due to the acceptance of LHCb detector on $\xi$ was discussed. Finally, the impact of pile-up was presented.
