Comment: V2A8C9 contains now the 10Hz clock signal coming from
the same section of the clock where the 100Hz sync signal is extracted.
It will be there even if we inhibit the pulser signals to the preamps

SYNC pulser is 200Hz because 
the gate generator produces double peaks from the 100Hz clock

v1a6c13-16 had a configuration error (Trigger window to  short) 
It's corrected at 14:55 (2018/10/30) on file 181030_Conf_BrikenFull_LowThrAdj_masterCLK.xlsx .

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

****3He tubes 12 and 7 (RIKEN) were shifted 3cm aprox from their position upstream (CHECK DATA).

F11 plastic (long plastic after MUSIC chamber) 
connected to DACQ.
The connections were re-cabled and verified.
F11 plastic has 0.2mm thickness (check!)
Current HV: 2000V

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
