Description
The laserwire is a non-destructive, commensal beam profile monitor and a highly viable, minimally invasive diagnostic already implemented at several accelerator facilities, with advantages for future collider applications. Here, a short-pulse, laserwire-based method is proposed to upgrade the laser system for the 160 MeV negative hydrogen ion beam of the LINAC4 at CERN. The improved system can perform combined transverse and temporal profile measurements, as well as access longitudinal parameters through temporal asynchronisation of the laser pulses with the beam bunches. Initial studies have been carried out by simulating the interaction of the laserwire with Gaussian-distributed 160 MeV negative hydrogen ion beams across a range of short-pulse durations and energies using Beam Delivery Simulation (BDSIM) software. These simulations have been used to parameterise the requirements of the upgraded laser system.
