Sat May 15 11:26:44 2021, Benedikt, General, TEM parameters
|
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 |

Sat May 15 12:11:54 2021, Benedikt, General, Laser-bunch-timing
|
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. |

Sun May 16 11:29:22 2021, Benedikt, General, Automated laser scans working
|
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. |
