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!

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.

  297   Fri Apr 30 10:55:34 2021 Jan GloriusDAQXray multi-triggers - blocking gate2021
From the CFD of Xray1 (90deg) we get multiple trigger signals every ~5sec for unknown reasons. 
No hint from the preamp signals.

The solution now is to have an extended blocking gate active in the trlo-config of node 2.
There is now a trigger_stretch of 2500ns for all Xray triggers:

trig_stretch(1)  = 2500ns;
trig_stretch(2)  = 2500ns;
trig_stretch(3)  = 2500ns;

This prevents the multiple triggers to reach the lmu (before_dt scalers)
However, this will also lead to a very small loss of good signal triggers that overlay within 2.5 us.

This has to be taken into account for deadtime determination.
