Comments:

For the moment there are three channels connected.

Channel 5 is AIDA plastic,

Channel 10 is the anode of the Ref detector

Channel 16 is the pulser.

TAC AIDAPL - CryA changed
After increasing the gain, x2 peaks in TAC

AIDA plastic changed.

HV was at 1000 V, it was changed to 1300 V

Coarse gain was changed to x5, Fg remains as it was.

I had only two minutes to enter (it was a rush). Better to verify it again

Problem with the sync checker appeared AIDA was not its notmal 14us out from DTAS.

Check with source shows we are in sync still

Nishimura san found the module used for the AIDA plastik in the last BRIKEN run. We put it instead of the TFA. It was kept in the same

setting conditions as in the earlier experiment.

A few detectors have moved, but for the moment I will not correct it.

Reference detector in channel 10. It is very noisy now. I changed the threshold from 1400 to 1600 but still noisy. It requires further attention

Comments: 60Co source with AIDA in, red box, CD 395 . The source is not centered. It is positioned (the center of the source) at 14.6 cm

from the beam side external edge of the frame (lower NaI numbers). The holder is touching the nose of AIDA.

The nose of AIDA is 16 cm from the external edge of the frame (down stream). In that position Si # 3 is at the center of the DTAS according to Tom.

We have to be very careful when AIDA is moved in. Some of the AIDA  flat connector cables are touching the connectors of our NaI cables.

No large displacements. Det Dyn1 seems to have slightly larger statistics. The assymetry of the two sides is clear, as it should be.

Reference detector might require repositioning of the optical fiber. It appears too close to the Cs peak and it is very noisy.

Source: 137Cs

Comments: Detectors show small drifts, of the order of the precision of the HV (we could apply 0.5 V corrections to align some of them, but I will not touch them now)

Dy16 looks quite off in the background measurement, but not with the Cs one !!!.

Calibrated spectra: Dy3 an An3 moved a little in the same direction, An12 looks also a little displaced.

Now I plan to measure some sources with AIDA in. It means that the sources will not be centered. The available distance from the oposite side to

the nose of AIDA is 16 cm.
