Entry  Sat Mar 21 13:37:53 2020, Laszlo, , MCP can monitor target,  
now with the MCP we can see clearly the effect of the target :) (scintillation?)
so we want to scan through the target thickness with the beam and choose the best position afterwards.
Entry  Sat Mar 21 13:44:16 2020, Pierre-Michel, Detectors, Recoil detector,  Recoil.pdf
We turn on Recoil detector, to use it as a monitor for target overlap.

MCP front -2500 V for highest signal rate.

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

Entry  Sat Mar 21 15:26:49 2020, Laszlo, General, SCRAPER is ON use again,  
Yuri puts back the scraper (Egelhof 1 - GE01DD1IG) into position = +19. (where it was in the evening)
Entry  Sat Mar 21 15:30:34 2020, Sergiy, General, go into the ESR,  
We are going into the ESR to check the electronics.
Use calibration sources (133Ba etc).
Entry  Sat Mar 21 17:21:57 2020, Laszlo, General, new Target density,  
Ulli and Nikos managed to set the target density to ~7E13  at 51K temperature

The cycle is checked again, it seems fine.

Entry  Sat Mar 21 17:34:10 2020, Sergiy, General, Recoils,  

We started recording the data from the recoils using the MCP from Pierre-Michael's experiment.

Entry  Sat Mar 21 18:13:22 2020, Shahab, General, rough comparison gas target off and on,  target_effect.jpg
rough comparison of life time at 10 MeV/u when target off with on. more noise in background means weaker signal.

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.
