(a) Raw data from the 2D CCD detector where the strong feature is the cross-correlator signal. The background has been subtracted. A height of about 10 pixels correspond to 0.2 mm and the width of the beam is a measure of the temporal convolution of the pulse-shapes of the laser and the bending magnet radiation. The horizontal position of the signal is a measure of the relative timing of the electron beam and the laser. The calibration factor is approximately 16 fs per pixel. (b) Horizontal lineout of the cross-correlator signal in (a) calibrated in femtoseconds.
