Cross-correlator for the diagnostics of 3D ellipsoidal shaped UV laser pulses for XFEL ultra low-emittance photoinjector

摘要

The cross-correlator described below excels in its high speed (>1500cm/s) and high amplitude of the diagnostic channel delay. Such characteristics allow the cross-correlator to scan pulses inside 300-microsecond long pulse trains, repeated with the frequency of 10Hz.
