14:30 pm to 15:00 run 45 crashed and stopped

I started run 45, and local filter turn green everything is ok.

Run 37 stopped by itslelf at 15:43. This was noticed at about 16:10 by observing that grafana data rates do not change.

Stop at Run COntrol.  LF looks  disabled.

Attempt to restart normal way --> run 38  --> failed

Attempts to load topology failed.

Cannot any more refresh or load the Run COntrol web page (192.168.0.133:5000)

Grzes is trying to fix the problem remotely, while we are starting changing of the target....

Run 35 stopped. An attempt to check if we can get 5 MeV  higher beam energy.

Started after beam current was reduced by a factor of 2

plunger run # 116

Earlier:   CUP#6  100 enA

Now: CUP#6   50eNA

Beam dump 1.8 enA

Collimator  0.8 enA

The operator is asked to keep the beam dump current not larger than the present value.

Supposed Distance = 10 um

position of the target = 10 um

micrometer = 11.7 um

Voltage = 7.9 V

Plunger off set 60 um

Which means we are running 60 um + 10 um (read from position window of plunger) = 70 um.

Observed that detectors at theta 143 degrees count most.  Is this because they see beam dump?

Run 29 with single gamma trigger

Plunger feedback system is not connected.

Supposed = 520

run 28 started

the beam is not the best focused. The operator works on this problem.

after run 45 I reset all spectrums and number_Ge_15 dedector not taking data.

i check the fans_monitor_scaler (EAGLE_array_monitor) monitor and number 15 Ge, number ACS 5 never change the color just staying white there is a problem.

As in the title, see below.
The data are still being constantly written on the disks with usual rate (also visible on grafena).
Greware is also seeing data.

beeper output:
no new data about the growth for 37 s !!!

New target mounted.

106Cd 1 mg/cm2

181Ta  1.2 mg/cm2

Problems in alignment. Offset of 100 um, in spite of the fact that a gap is visible at this distance, and a hair could be moved in between stopper and the target.
Decided to close and pump anyway, after several attempts to improve the alignment.

Stopper same as before, slightly more stretched.

the daq resolved at 23:15

start new run: run 54

At about 12:00, 13/03/2023 (about  17 hours after the beam was stopped), a measurement of activity of the beam line was performed using  FH 40G-L10 meter.

Radioctivity run 65 stopped before the measurement, radioactivity run  66 started after the measurement

Background level 120 ns/h

Target, stopper, the forward half of the target chamber - dismounted.

Approximate distance from the target position (upstream), approximate activity

10 cm    500 ns/h

25 cm    420 ns/h

35          350 ns/h

40          350 ns/h

50          200 ns/h

75          170 ns/h

the beam was lost at 20:46. The operator is working to solve the problem.
