Root: 201905221550_137Cs_with_Aida.root

Rates: 7.5 kHz (Dyn), 7.8 kHz (Anodes)

Comments: 137Cs source with AIDA in, Source CS401, 4763. 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.

Individual rates (kHz), remember the source is not at the center, so we expect assymetry in the counting rates):
