Beam was off for a few minutes, after coming back the number of particles was reduced for a few minutes and then increased to the values at the beginning of the run.
  490   Thu May 27 08:26:15 2021 Yuri, BeatrizGeneralOptimisation beam position on target and scraper position2021
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.

  16   Mon Jul 8 14:57:07 2019 Yuanming XingDetectorsThe 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.

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.
