Description
PAL-XFEL has been operating two beamlines simultaneously since 2021. The simultaneous operation method involves generating and accelerating single bunch of electrons at 60 Hz to provide 30 Hz beams to the hard X-ray(HX) and soft X-ray(SX) beamlines, respectively. It is intended to switch to a method developed by SwissFEL, which is capable of providing 60 Hz beams to both the HX and SX beamlines. To implement this, the two adjacent electron bunches are spaced 25ns apart, and the operating frequency is designed so that the RK operates at 20 MHz. We chose a method of driving the RK using a combination of LLRF and SSA. The initial LLRF prototype was developed and showed the RMS stability 0.007 %(Amplitude) and 0.02 °(Phase), which needs improvement nearly ten times. We are cosidering and seeking for solutions to improve the RMS stability.
