|
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

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

Fri May 14 16:37:01 2021, Benedikt, General, Status update
|
Right now, we have to adjust the ion beam a bit to overlap better with the laser beam.
We keep the laser wavelength at resonance with the ions and try to optimize the fluorescence signal on the XUV detector while moving the ion beam. |
|
Fri May 14 11:01:33 2021, Benedikt, Calibration, Laser Beam adjusted
|
The laser beam was adjusted in his position to overlap better with the ions.
Ion beam is destroyed at scraper position 1VO 6 mm and 2VO 4 mm; the laser beam looses half its power at 1VO 6mm and 2VO 4 mm.

|
1.) ion lasser overlap and scraper test
2.) change bunching frequency to middle of ecooled coasting beam
