  Many experiments in attosecond science will benefit from attosecond pulses at
high repetition rates with sufficient photon flux for pump-probe experiments.
We use 7fs, 800nm pulses from a non-collinear optical parametric chirped pulse
amplification (NOPCPA) laser system to generate few-pulse attosecond pulse
trains (APTs) in the extreme ultraviolet (XUV) at a repetition rate of 100kHz.
The pulse trains have been fully characterized by recording FROG-CRAB
(Frequency-Resolved Optical Gating for Complete Reconstruction of Attosecond
Bursts) traces with a velocity map imaging spectrometer.
