Comment: We started a Ge filling manually, to check if the funny behavior of the 
Corr_BR_BR can be reproduced. It remained clean. So we do not yet what caused the 
funny behavior. 
Funny behavior definition: periodic peaks appeared in the Corr_BR_BR file

The synch software problem will be solved tomorrow. 

Tomorrow definition: a mystical land were 99% of all human productivity, motivation 
and achievement is stored

We put the 252Cf source and check the aligment of 3He tubes gains:

File: 181025_1600_252Cf_gaincheck.root
All OK except 133, 35 and 140

He133: peak at 744keV
He135: peak at 783keV
He140: peak at 739keV

No gain correction  applied at the moment but should be verified
before experiment
