The data from google sheet obtained 14:17 07/03/23
Plunger Run :
Micrometer :
Supposed Distance:
Position :
Run 23 Stopped due to some unexpected spikes in the
voltage of collimator.
The plunger did not responde to change distance.
The chamber was opened and observed some yellow spots
seen over the Cd target.
Run 24 has been started but no beams at the moment.
EAGLE is opened.
Just colecting background.
Run 26 Started
Beam 9 enA on the collimator
run 28 started
We will change the trigger and we stopped the run number 29
We hane now g-g trigger started.
Run 30 started
EAGLE is closed now
We gave a break to test the cable connection of target, degrader, beam dump and collimator.
Run 30 continues to collect data, we did not stop it.
But not much usefull data in it.
Plunger Run : 48
Supposed Distance = 10 um
position of the target = 10 um
micrometer = 6.5 um
Voltage = 7.957 V
Plunger off set 60 um
Which means we are running 60 um + 10 um (read from position window of plunger) = 70 um.
Run 32 Stopped
Run 33 Started
20:50 Observed beam dropped by a factor of 2 (1.5 enA on the beam dump). Asked the operator to improve beam.
run stop 22:53 acquisition problem
Run 40 stooped
Run 41 started
Plunger distance 10 um

Run 47 stopped and distance changed from 50 um (+ 100 um offset) to 150 um (+ 100 um offset)
Last plunger run for 50 um (+ 100 um offset) is 495
run control = 49
