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. |

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. |
