Run 59 collected data using gg trigger radioactivty
Run 60 trigger changed fropm gg to single g.
Just in the beginning a few minutes gg data could have been collected. |

target and stopper and beam dump dismounted.
only the constructional elements of the plunger remained.

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. |
