TI - Development of the Transverse Beam Profile Monitors for the PAL-XFEL J2 - Proc. of IBIC2014 AB - The PAL-XFEL is an X-ray free electron laser under construnction at the Pohang Accelerator Laboratory (PAL), Korea. In the PAL-XFEL, the electron beam can make coherent optical transition radiation (COTR) due to the microbunching instability in the compressed electron beam. In order to obtain transverse beam profiles without the COTR problem, we are developing scintillating screen monitors (with the geometric suppress method) and wire scanners. In this paper, we report test results at the test facility and progress in the development of the screen monitor and the wire scanner for the PAL-XFEL.
