Yuri, Beatriz | General | Optimisation beam position on target and scraper position | 2021 |
Optimised overlap with the target by shifting the beam from -11.5 to 12.8 mm. This lead to an increase of the DSSSD rate of a factor between 2.5 or 3.
Adjusted scraper position by looking at x-ray rate and move it from +1 to +2. |

Yuanming Xing | Detectors | The measurement of the tilting angle | |
As shown in the figure, the detector is tilted by a certain angle which is about 45 degree.
The tilted angle is defined as angle B.
We measured angle A using the vertical laser line (red) and papers with a straight line edge. So we can marked
the line denoted by the laser line when the paper is put on the holder.
In the beginning, the angle A is measured as 43.3±0.5 degree. So angle B= 46.7±0.5 degree
After the adjustment of the detector (to make it in the center of the chamber), the angle A is measured as
43.1±0.5 degree with another paper. So angle B= 46.9±0.5 degree. |

Tino, Rene, Yuri, Laszlo, Markus | Runs | change of settings | 2021 |
from now on, everal beam setting will be different. We could not get the beam back to were it was before. When the scraper was pulled back by 2 cm, the loe/energy beam was visible again via cap.
Schottky. However, no x-rays could be observerved during the target-on phase.
Hence the interpretation:
beam position has change at least a few mm, at most 2 cm.
Will now try to get a new overlap with target and need to adjust the detector position too.
All online - Si spectra are cleared. |
