Jan Glorius | Calibration | run0039 - Xray145 calib Pb210 d=305mm | 2021 |
Efficiency calibration in the lab
************************************
CAUTION!
This is now GEM1800 @ 145deg distance
But still operated as Xray1 in DAQ
************************************
Rate is increasing slowly 200 > 400 Hz, more noise coming in.
Also possible source holder movement!
Resolution still good.
Take this run with care!

Jan Glorius | Calibration | efficiency xray 35deg | 2021 |
the attached efficiency curve for the 35 deg. xray detector is made with the runs
e127b_run0015.lmd
e127b_run0016.lmd
e127b_run0017.lmd + e127b_run0019.lmd
All of them were taken in the lab (not in ESR).
This is a very preliminary analysis!
E.g. deadtime has been estimated and was not cleanly determined. |
