Entry  Sat Mar 21 22:57:28 2020, Laszlo, Jan, DAQ, changing cables of the Xray 90 and 145,  
Energy signals of 90 and 145 degree detector have been checked and exchanged
They were connected to the wrong ADC channel.

Now 
E_Xray2 and t_Xray2 should belong to 90 degree
E_Xray3 and t_Xray3 belong to 145 degree

Entry  Sat Mar 21 21:36:06 2020, Jan, Runs, target incident,  run67_target_incident.png
in run 66 or 67 we had a single ESR cycle for which the target didn't switch off for new injection and deceleration etc.
Very likely the DAQ also didn't get an OFF signal and collected OFF data to the TRIGGER=1 (ON data) branch.
As a consequence we collected about ~100 counts on the Si in one shot, which was about ~20 counts before this shot.

attached:
1.picture of the target density and beam current at this time.

Ulli and Nikos managed to set the target density to ~7E13  at 51K temperature

The cycle is checked again, it seems fine.

Use calibration sources (133Ba etc).

previous position of the beam at target was -3mm (for the night position)
max. intensity position of the beam at target 1s -1mm. --> now it is set to this position

now Ulli also increasing the density of the jet. Right now Ulli is warming the noozle. --> takes 1hour roughly.
