Accurate synchronization between short laser pulse and electron bunch using HGHG output at 266 nm as photo-cathode laser for RF-gun

摘要

We report a new scheme to realize accurate synchronization between the electron bunch and seed laser by using HGHG output at 266 nm as photo-cathode laser for the RF gun. One by-product of this method is the reduction of the energy fluctuation in addition to the reduced time jitter.
