 Sat May 1 22:34:16 2021, Jan Glorius, Calibration, efficiency xray 90deg, 2021 
|
the attached efficiency curve for the 90 deg. xray detector is made with the runs
e127b_run0008.lmd
e127b_run0009.lmd
e127b_run0010.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. |

Here is the table of energy calibration lines from Am241 for all Xray detectors for several measurements.
Also the linear fit parameters [ E(ch) = A*ch + B ] are given at the bottom of the table.

Tue May 4 14:34:51 2021, Jan Glorius, Detectors, Xray weight control induces signals, 2021
|
When the readout/control of the det. weight control via serial connection is active, there is a clear signal induced in the Xray detectors for each command sent.
The solution for now is, that we activate weight control NOT DURING MEASUREMENT! |
