Title A supersonic gas jet-based beam profile monitor using fluorescence for HL-LHC
Abstract The High-Luminosity Large Hadron Collider (HLLHC) project aims to increase the machine’s luminosity by a factor of 10 as compared to the LHC’s design value. To achieve this goal, a special type of electron lens is being developed. It uses a hollow electron beam which co-propagates with the hadron beam to act on any halo particles without perturbing the core of the beam. The overlapping of the two beams must be carefully monitored. This contribution presents the design principle and detailed characteristics of a new supersonic gas jetbased beam profile monitor. In contrast to earlier monitors, it relies on fluorescence light emitted by the gas molecules in the jet following interaction with the primary hadron beams. A dedicated prototype has been designed and built at the Cockcroft Institute and is being commissioned. Details of monitor integration, achievable resolution and dynamic range will be given.
