Description
Since the start of clinical operation in 2009, more than 10,000 patients have been treated at HIT with proton, carbon, and helium ion beams. Three Supernanogan ECR ion sources are operated for routine clinical beam delivery.
A fourth Supernanogan ECR ion source is available at the HIT test bench for studies on source optimization and injector development. As part of an ongoing measurement campaign, the influence of dual-frequency microwave heating using 14.5 GHz and 18 GHz on the extracted ion beam is being investigated. Beam characterization is performed by beam current and beam profile measurements.
This contribution presents the experimental setup and first results of the dual-frequency studies. In addition, an outlook on further activities at the HIT test bench is given, including the commissioning of a newly developed 4-rod RFQ for the HIT injector linac, aimed at increasing particle transmission and supporting future high-intensity operation.
