 Sat May 22 14:53:34 2021, Beatriz et al., General, DSSD Movement, 2021
|
DSSSD moved to the most in position in order to try to scrape the beam with the scraper. |
|
Sat May 22 16:28:10 2021, Laszlo, General, DSSSD movement, 2021
|
The DSSSD is moved back to its measurement position(-25mm). |
|
Sat May 22 16:29:07 2021, Laszlo et al., General, coolers are back, 2021
|
we can measure again.

Sun May 23 02:16:47 2021, Laszlo, General, quick comparison between different scraping positions, 2021

So far we did 3 scraping positions:
- 30mm away from beam axis (lmd72-75)
- 25mm away from beam axis (lmd78-80)
- 20mm away from beam axis (lmd76-77)
below one can see the comparison of the scrapings for the DSSSD spectrum. Please mind the different amount of data collected |
