Abstract
| Over the last few years, CERN has successfully designed, built, and commissioned the smallest RFQ to date, the one meter long PIXE-RFQ operating at 750 MHz. Its compactness offers a unique opportunity for education and public presentation of the accelerator community: A duplicate ma- chine called ELISA-RFQ (Experimental Linac for Surface Analysis) will be exhibited in the Science Gateway, CERN’s upcoming scientific education and outreach center. It will allow the public to approach within a few centimeters a live proton beam injected into air, which is visible to the naked eye. The construction of the ELISA-RFQ has been completed in 2022. In this paper, we present the results of low-power RF measurements as well as field and frequency tuning. |
