Beam Profile from H6A, 10.10.2011 11:40

BeamRef settings for all magnets, File H6B.702

Module order:

CNM-V1 (draws a lot of current, gives only low signal)
BSTD1-N (for height information)
CNM-V2 (works fine)
 

Attatchment 1: Stack config, beam from right. In the box the stack is mounted with the labelled side of the BSTD1-N module on top (90deg rotated w.r.t. photo)

Attachment 2: the top edges of the sensors coincide -> when the beam hits the last strips of the BSTD, it also hits the pitch adapter region of the CNM sensors

micronbaby p-spray/irrad
HV = -100V
beam on, baseline of irrad APV reduced

APV #2 (I²C addr. 40) deactivated, latency error after initialization, reset line is open

Sr90, large scintillator,
Origami Mod. #4
HV=+-40V, Ibias=1,30µA
CO2 cooling on, Tin=-20.5°C, Tout=-21.5°C

Lab measurement with new dark box but old, large scintillator

SMU:  +HV=Inv.Nr. 545-77    -HV=Inv.Nr. 540-702

HVret configuration:

0 ... switch open / not connected
1 ... switch closed / connected
 

J7... HV ret @ hybrid

same as run108
Noise of p-side APVs in run108 was very high --> repeat measurement!

Sr90, small (new) scintillator, new trigger unit
Origami Mod. #4
HV=+-40V, Ibias=1,6µA
CO2 cooling on, Tin=-19,6°C, Tout=-21.3°C
