Development of supersonic gas-sheet-based beam profile monitors
| Description | The main findings of the HLLHC-UK and HLLHC-UK Phase II projects are reported by the project coordinator (University of Manchester). The Liverpool has developed and successfully delivered gas jet-based monitors for characterizing proton and heavy ion beams in the Large Hadron Collider. One of the monitors was installed in the LHC beam 1 in 2023 and is now used as a routine tool for machine operation. It is the only monitor capable of measuring protons and ions from injection to top energy, and provide detailed insight into the beam's profile and emittance. As such, it is an absolute game-changing technology for any future high energy collider and the only technology able to give this insight. The project also takes advantage of CERN's Electron Beam Test Facility (EBTF) for offline measurements during periods when the LHC is not running. This will be particularly interesting during LS3 when EBTF will be used for preparing HLLHC commissioning. This will give critical insights for technology optimization whilst also measuring for the first time, cross sections of high intensity beams, halo measurement opportunities and overall monitor optimization. |
| Exploitation Route | The BGC technology is ideal for any high energy, high intensity accelerator. It can characterize demanding beams for which no alternative beam monitoring techniques exist. There is also excellent interest from the medical research community and some exciting options for pencil shaped beam being used as high resolution microscopes. This potential was highlighted as part of initial studies within the Innovate-UK funded qHAM project (quantum Helium Atom Microscope) and the STFC-Funded QuantumJet and JetDose projects into online dosimetry. |

| Description | The main findings of the HLLHC-UK and HLLHC-UK Phase II projects are reported by the project coordinator (University of Manchester). The Liverpool team's contribution was the development of a non-invasive gas jet-based beam monitor. This has given unique insight into the Large Hadron Collider's proton and ion beams, and is being considered as an interesting option for the characterization of surfaces, electronics materials, material sciences, and medical applications, especially online dosimetry. Collaborative R&D with inter/national partners such as DCF, Birmingham University, CNAO and IBA is ongoing. |

| PI Contribution | My team designed, manufactured, and commissioned the beam-induced fluorescent profile monitor based on a supersonic gas jet at the Cockcroft Institute inside the Daresbury laboratory. The monitor was tested with an in-house electron gun to potentially show the ability to measure the proton beam in the LHC. The team accumulated the operational experience of this monitor and studied the gas dynamics using both simulations and experiments to optimize the geometry used in the monitor such as sizes and distances of the nozzle and skimmers. The first monitor was delivered to CERN and tested in a standalone lab and electron beam test stand. The monitor has been installed at the LHC and is waiting for the experiment. |
| Collaborator Contribution | GSI provided expert views on beam-induced fluorescent cross-sections, optics design for such monitors, and imaging intensifiers under the CERN-GSI collaboration contract. They also offer one intensifier camera for test in the CERN experiment. CERN provides space and professional support from the vacuum group, mechanics group, and engineering design group for the experiment that occurred at CERN. |
| Impact | 1. Demonstrate the BGC monitor can be used for a hollow electron lens. 2. Install the BGC monitor into the LHC. This collaboration involves experts in disciplines such as accelerator physics, detector, vacuum science, and mechanical engineering. |
