Mon Mar 23 14:32:03 2020, Jan, Analysis, runs_100to104 NO-SCRAPER RESULTS, 
|
Without scraper, we have very few (p,g) counts, hard to get numbers quickly, maybe ~50.
X-rays look fine! |

|
Uwe found out, that there was some common ground effect between 90 and 145 degree detectors. after moving the grounds, we could record much more nicer (Gaus
shaped) peaks in the spectra. Now we continue with this settings |
