Research Abstract

3D-BCD monitor enables non-destructive measurements of the longitudinal and transverse BCD at the same time. We verified this transverse detection with multiple EO crystals at SPring-8 photoinjector test accelerator. In the high-order harmonics (HH) FEL seeding, it is required to maximize and keep 6D-phase-space overlapping between HH-laser pulse and electron bunch. We constructed a relative timing drift monitor based on EO-sampling, which measured the timing differences between the seeding HH-laser pulse and the electron bunch, using a common external laser source of both HH-driving and EO-probing pulses. Keeping the peak wavelength of EO signals at the same wavelength with our feedback system, we provided seeded FEL pulses with a 20-30% hit rate during pilot user experiments. For achieving the upper limit of temporal resolution, we developed high-temporal-response EO-detector crystals and an octave broadband probe laser pulse with a linear chirp rate of 1 fs/nm (flattop spectrum).
