(a) Pulse intensity diagnostic consisting of a fast diode (active area 0.2 mm × 0.2 mm) and a PIPS diode (active area 300 mm2). Both diodes measure the scattering from a thin (150 µm) Kapton film. A pair of slits is located upstream to reduce the spatial extent of the beam if needed. (b) Examples of single-shot raw traces from the Acqiris digitizer for two pulses at various time separations of 0.70, 4.55, 8.75 and 23.80 ns. |
