Description

To increase the beam transmission efficiency, a new buncher has been installed on the injection line of the HIRFL injector cyclotron SFC. This new buncher uses saw-tooth RF waveform with an effective voltage of up to 2.54 kV and operates at half of the SFC cyclotron RF frequency. With this half-frequency matching mode, we achieve 100% theoretical longitudinal matching between the injector SFC (H=1) and the main cyclotron SSC (H=2). As a result, the beam transmission efficiency has doubled compared to the original full-frequency mode.
