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

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

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
