Laszlo | Calibration | run107 - Xray90 calib Am241, distance 167.5mm | |
Detector: 90
Source: Am241
Distance: 167.5mm
Start time: 15:46:49 23.03.2020
Stop time: 17:32 23.03.2020
file name: run107_xxxx.lmd
avrg. rate: 610Hz
dead-time: 7%
not Gaussian shaped peaks, after previous investigations with the scope, the scope is disconnected.
Just to mention, in order to improve deadtime the other two Xray dets are disconnected. |

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! |

beam: 124Xe54+
energy: 10 MeV/u
we run at MAX INTENSITY as we can: SIS was increased to its top, but unfortunately we still end up with 1.5e9 at injection from SIS. Sergey also optimized some stuff.
purpose: data with TARGET ON and SCRAPER OFF --> this leakage current spikes associated with primary scattering from the scraper edge seem to disappear, but we get still 10kHz rate on the detector a few sec after injection(this small "bump"
after the peak in the Si current - see the picture below)
