Description
The TWOCRYST experiment at the CERN Large Hadron Collider provides a unique setup to study the behaviour of high-energy beam particles channelled by bent crystals. Two two-dimensional detectors in Roman Pots enable direct observation of channelled protons at energies from 0.45 TeV to 6.8 TeV. We present measured channelled-beam distributions for two bent silicon crystals with 50 urad and 7000 urad bending and compare them to combined beam-dynamics and particle–crystal interaction simulations including the full LHC lattice. The measured positions of the channelled beam is compared with beam-position-monitor data of the main beam to assess the sensitivity of the channelled-beam trajectory to realistic orbit drifts, providing key input for the requirements of future bent-crystal-based fixed-target experiments.
