Description

The TWOCRYST experiment at CERN is a proof-of-principle setup designed to demonstrate the feasibility of the future ALADDIN experiment, part of the Physics Beyond Colliders programme. The setup comprises two bent crystals installed in the LHC beamline at Insertion Region 3 (IR3). The first crystal (TCCS) extracts particles from the beam and directs them onto the second crystal (TCCP). This paper presents the FLUKA simulations performed to assess the crystals alignment procedures for various beam and crystal configurations. Since the alignment of the crystals is achieved mainly by monitoring the Beam Loss Monitor (BLM) signals in the vicinity of both bent crystals, the main objective of the simulations is to evaluate the corresponding BLM responses at each step of the procedure. These simulations aim to confirm the validity of the alignment process by demonstrating that the BLM signals can be reliably used to gauge proper crystal alignment. The simulation outcomes are presented here and were found to be consistent with experimental observations.
