|
M.Steck et al. discussed about the E-Cooler and found a possible issue. They asked for enterance to the ESR. Since nobody else was in the HKR and anyway
nothing was running because of some other issues, I told, the experiment would not be disturbed and they could enter and do things. (Sth. like putting
some repeller electrodes onto hand and other magical things).

|
We use different scan types (manual scan) or constant laser wavelengths to check the effects of laser cooling in the Schottky diagrams (fluorescence can
not be seen in the detector), for different bunching amplitudes and frequencies:
- Scan from 1028.950 -> 1028.940, stepsize 0.001 every 10 sec

| Attached to this elog entry is a short manual for the xuv-detector control. If anything is missing or not understandable I can change anything. |

To implement the bunch Signal Generator (DSG821 inside ESR) you have to:
1. unplug the Ethernet cable

Thu May 13 01:21:30 2021, Sebastian, General, Current schedule ... so far
|
1.) check h=2,4,6,7,8,10 .... bunching frequencies with different amplitudes (signalgenerator), Ecooler ON, Laser OFF --> record schottky and "normal" DAQ
2.) Ecooler ON, Bunching ON, Laser ON (wavelength fixed and/or scanned)

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)

There are cooling problems of some accelerator devices
short break, hopefully :)
Laser is switched of for some rest |
