We changed the horizontal position of the laser beam a bit, so that we maximized the fluorescence signal on the XUV detector (coasting beam, scanning laser (0.03 Hz)).

Old parameters: OffsetM Ax 0.00; Bx 0.00; Ay -0.08; By -0.40
New parameters: OffsetM Ax 0.00; Bx 0.35; Ay -0.08; By -0.40

Optimizing the laser bunch timing.
h = 7 (9.0389145 MHz)
Reprate is already set to same frequency.


Results: For h=7:
4 ns delay results in a maximum fluorescence rate in the XUV detector
25 ns delay shows the highest intensity in the Schottky spectrum while the laser operates at 1028.940 nm.

The automated laser scans are working now.
We can now scan with the following functions: triangle, sawtooth, cosinus/sinus, arctan, min (linear scan, than stands still)

We are now testing these scan functions with coasting beams; ecooler 10 mA.
