Sat May 22 17:15:26 2021, Laszlo, General, Scraper position, 2021
|
We found the beam axis with the scraper to be -17.5 mm.
The Scraper position set to +12.5 mm, 30 mm relative from the beam. |

|
The DSSSD is moved back to its measurement position(-25mm). |
|
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. |

The intensity is lower because they are preparing a 4He beam for R3B.
For a few minutes there were no particles in SIS.
We have quite some fluctuations in intensity in this run. |
