Thu Oct 6 14:50:30 2016, JL Tain, A Tolosa, A Tarifeno,..., 252Cf
|
First measurement with 252Cf source to check the calibration.
AIDA was in place so the source was at the right height
but displaced about 10cm from the center.

We mount back all preamplifiers
Initially we used all the PA coming from US, the repaired and the new ones.
There was an issue with the new ones (strong noise and cross talk)

Low amplitude noise component.
The figure shows the composition of the low amplitude noise

|
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

Sat Oct 8 01:18:51 2016, JL Tain et al, DACQ
|
| We increased the pretrigger delay for ADC5 from 350 to 400 |
|
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.

Sun Oct 9 15:49:41 2016, JL Tain et al, Power shutdown
|
Due to maintenance operations of the Wako electrical
company there is a risk of power shutdowns on Saturday,
Sunday and Monday from about 8 am to 8 pm.
