RIKEN tubes on the AIDA side with the SHV right angle connector will protrude
by ~95mm in the HYBRID configuration (with CLOVERS).
In the current AIDA DSSD configuration there are six detectors occupying 45-50mm

Tue Nov 22 09:26:04 2016, A. Tarifeno-Saldivia, Noise check
|
Run for checking the noise just after turn on the crates, without high voltages on the PREAMPS.
Attached calibrated histogram for the full BRIKEN detector.

Fri Oct 7 10:42:52 2016, JL Tain et al, Noise
|
We investigate the effect on the noise in ORNL tubes of using a differential PA.
We connect the tubes in current PA10 (126-140) to one of the new diff PA

Sun Oct 9 04:20:47 2016, JL Tain et al, Noise
|
We check for the appearance of spurious signals in the preamplifiers.
We set all HV to zero and run a measurement for several hours.
