THE PROJECT OF RFQ LINAC FOR AN EDUCATIONAL LABORATORY AT RAC OF MEPHI

RFQ linac of light ions with the energy up to 2MeV/amu and the charge-to-mass ratio ≤1/3 is proposed at the Radiation-Acceleration Center (RAC) of MoscowEngineering Physics Institute (MEPhI). The accelerator is intended for educational and research purposes. In the report, RFQ designs with two different frequencies of 150 MHz and 433 MHz are considered as possible candidates. Two types of the RFQ designs using either a constant or an increasing intervane-voltage distribution along the structures are compared and discussed. The former type is a conventional RFQ, and the latter type allowing an increased energy gain results in a shorter accelerating structure, while it requires a higher RF power.
