Experiments with the high current RFQ prototype for GSI

A new high current injector (HSI) for the UNILAC and the SIS synchrotron for all ions up to uranium is planned at GSI. The spiral-RFQ accelerator accepts low energy (2.2 keV/u), high current (25 mA) beams with low charge states (U/sup 2+/) at an operating frequency of 27 MHz. Results of particle dynamics calculations and structure development for the first crucial part of the HSI-RFQ, where all bunch forming is done, are presented together with results of rf measurements and first beam tests.<
