Description
As part of the ongoing Korea-4GSR (Fourth-Generation Synchrotron Radiation) project, a 200 MeV electron linac is being developed based on an S-band photocathode, rather than the conventional thermionic gun approach. The gun provides high electron energy (4 MeV) and low emittance, which simplifies the design of the initial accelerating RF system, magnets, and beam transport to the booster. The basic concept of the linac builds upon the successful PAL-XFEL design and has been further optimized to support 64-multibunch generation, precise energy feedback, injection timing control, and higher charge operation. Plans for gun testing and commissioning will also be presented.
