Start: 14:32

Stop: 14:37

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.
