Subject: Issue? Scrapers at E-Cooler 
Carsten* forwarded me an E-Mail from Markus yesterday. "Betreff: Scraper im ESR Elektronenkühler"

- Markus has tried to get moving the scrapers at E-Cooler last week. But he got some issues.
- The expert (Herr Robert Boywitt, Abteilung BEA) has been contacted and he is working on this issue.
- The scrapers move in one follows the instructions (please attached screenshot).
- However it was also noticed that the actuators for the scrapers show now tolerance of "2 mm". Frown This can affect the accuracy and the reproducibility of the ion- and laser-beam positions, e.g the overlap.


* he was so lazy that he could not post this in the ELog.
