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

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)

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. |

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.
