TI - Bunch Arrival Time Monitor for PAL-XFEL J2 - Proc. of IBIC2014 AB - The X-ray Free Electron Laser project in Pohang Accelerator Laboratory (PAL-XFEL) requires high stability of bunch arrival time, and measurement resolution better than a few femtoseconds. The pickups of the electron Bunch Arrival time Monitor (BAM) for PAL-XFEL have been developed and simulated. The BAM pickups are based on an S-band monopole cavity with two coupling loops. The prototype BAM has been fabricated and installed downstream of the accelerating column at the Injector Test Facility (ITF) for PAL-XFEL. In this paper we will present the recent measurement results on the beam test of the BAM as well as a proposed strategy for developing the BAM for PAL-XFEL.
