Run 34 Started (33 was stopped due to acquisition problems)
Plunger Run : 105
Supposed Distance = 10 um
position of the target = 10 um
micrometer = 12.7 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.
at the first 10 min det # 5 was switched off
Ge det # 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
old scalers: 5 2.5 8 5 8.5 3 5 1.5 5 8.5 8.5 7.5 2.7 2.7 5 kHz

beam dump current 3nA
det # 5 scaler 7.7 kHz
stoppped 00:02 because beam current was reduced byu a factor of 2 (see note on the next run)

Fri Mar 3 20:50:31 2023, IK, MP, GJ, Other, , Data analysis, Ge spectra 
|
Ge rates increasing, similar to what it was 24h before. Asking to decrease beam intensity by a factor of 2.
Attached Ge spectra before decreasing.
Before decreas beam current was 1.75enA, afterwards 1.1enA. |

Wed Mar 1 00:14:28 2023, MP, Other, , Beam, beam energy
|
Beam energy measured: 148.2 MeV
Mind that this may be an overestimate (by ~1-2 MeV) |
|
Wed Mar 1 12:51:33 2023, MP, Runs, , Beam, beam on the target
|
Beam on the target:
target+stopper+beam dump: 25 enA (1.7 pnA) not stable
5 mm collimator: 0.8 enA
data taking continued with run 0023 |

|
Mon Mar 6 09:53:06 2023, OST, Problems, , Beam, Beam dump decreased 2.5 nA to 1.5 nA- stopped run 41
|
9:20 to 9:50 am beam current stayed 2.5 nA . After 9:50 am decrease 1.5 nA |
|
Mon Mar 6 17:19:24 2023, OST, Problems, , Beam, beam unstable and a little high
|
16:30 beam increased 5 mb/s to 9 mb/s and stayed 1 hour 9 mb/s
17:10 beam fixed. stable |
|
Tue Mar 7 09:18:01 2023, OST, Problems, , Beam, run number 44 crashed and local filter turned red-but data saved
|
9:08 local filter turned red. Both .caendat and LF .adf files still incrementing. Stopped run 44, started run 45, looks OK.
|
|
Tue Mar 7 09:20:53 2023, OST, Problem Fixed, , Beam, run 45 start-local filter turn green
|
I started run 45, and local filter turn green everything is ok. |
|
Tue Mar 7 20:42:03 2023, IP, Problems, , Beam, beam unstable
|
There was a problem with the beam from 20:19 to 20:30.
Now it is fine. |

run data =
RU = 8.69 MB/s
LF = 3.79 MB/s
Eagle Rated ch4: around 2.3 kHz
plunger: (2:48)
plunger run = 514
actual distance = 382.7 um
supposed distance = 382.7 um

Wed Mar 8 07:30:15 2023, KS, KSz, Problems, , Beam, beam unstable
|
The beam was unstable from 7:18 to 7:25. |
|
Wed Mar 8 07:57:05 2023, IK, Problems, , Beam, beam unstable
|
The beam was unstable from 7:55. Stabilized around 8:03.
Counting rates are higher, EAGLE det4 went to ~2.5kHZ from ~2kHz (attached).
According to the operator, a bit of a tuning was done, current is 1nA.
