|
Run 31 was stopped, because plunger distance is reduced to the mininimal one.
It takes time, in the meantime, after some break, run 32 was started, with no beam. |

|
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. |
