45GHz/20kW gyrotron setup with automated output power control for ECR ion source

摘要

The 45 GHz / 20 kW automated gyrotron setup de-scribed below is intended for use in FECRAL (Fourthgeneration ECR ion source with Advanced design inLanzhou, China) superconducting ion source. The FE-CRAL was proposed by Institute of Modern Physics(Chinese Academy of Science) for using in next genera-tion Heavy Ion Accelerator Facility (HIAF), which re-quests ion source capable of delivering 50 pμA of 238 U 34+pulsed beam and 25 pμA of 238 U 34+ CW beam for injectorof a superconducting heavy ion linac [1, 2]. When used asa part of such facility, the microwave source must satisfythe very strong requirements both for output radiationparameters and for possibilities of system integration.
