Noise check:
- He032, He034, He036, He038 have noise peak @ 15 keV (black = He032, red = He034, green = He036, blue = He038).
Tubes He031, 33,35 and 37 have not this peak. |

Little noise in some tubes:

We tried to improve the noise by moving cables around
but it didnt work. So we leave as it is.

Comment:
Tube 121 is noisier than the others (see fig).
Issue:
all the channels connected to PA3 and PA4
have twice the number of counts than the remaining channels (!?).
Actually the pulser counts.
Solution:
This channels are from UPC tubes and are connected to pulser PB-5.
We found that the threshold of external trigger was set to 1V
instead to 1.8V as before and this was producing a double pulse (see photo)
like triggering on the fall and rise of the trigger pulse.
This happen whenever the threshold as below 1.6V.
We do not understand this: the signal has +2.2V and no apparent ripple (!????).
We set threshold to 1.8V and now is OK |
