Acceptance and Transmission Simulations of the FETS RFQ
| Description | The Front End Test Stand is a test accelerator for developing high power proton injectors. Injectors are the very front end of a proton linear accelerator, used to accelerate particles from rest up to energies of a few MeV. FETS has a number of novel aspects, including the high beam current (60mA at 10% duty cycle) and fast beam chopper (arbitrary pulse lengths with nanosecond rise times). FETS is an ongoing project, of which UCL is no longer a part, but has demonstrated a completely new method of designing RadioFrequency Quadrupoles. FETS also functions as a test stand for ion source development for the ISIS spallation neutron source: significant progress has been made on the maximum current and pulse duration extracted compared to ISIS, with more than a tenfold increase in average current. |
| Exploitation Route | Facilities that wish to design high power proton accelerators - such as the CERN Linac-4 injector or the European Spallation Neutron Source (ESS) - have already made use of the ion source improvements achieved on FETS. Outside these areas impact is currently limited, since few areas beyond high energy physics research require such intense proton beams. |

| Description | Improvements to the FETS ion source have fed into improved performance of the ISIS spallation neutron source. ISIS is used by a number of different areas of industry, both in the UK and by visitors from overseas, primarily looking at material structure. Neutron spallation provides a unique insight into the nuclear structure of materials. |
