Abstract
Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.

Sector | Academic/University |
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. |
