Project: MicronOrigami_gross 
Subject: run ATTENTION: wrong bias voltage 
Run Number: run009 
Events: 31650 
StartTime: 15.10.2012 19:28:30  
EndTime: 15.10.2012 22:08:31  
Data: Crap 

ATTENTION! Bias voltage was +-100 V instead of +-50 V 

Origami Stack 2: Origami #4, #3, Wedge new1, old
HV = +-100V

Ibias=12.3µA
 

beam position:
vertical: between APV 1&2 (of 6)
horizontal: centered on APV#1 ->  right side of sensor

Position of xy table:
x = 23, y = -25


Temperatures:

Origami #4: In=-33 degC / Out=-34 degC
Origami #3: Out=-35 degC (temperatur sensor of inlet is not working)
Wedge new 1: Out =  -17 degC, cooling block = -14 degC
Wedge old: Out = -16 degC, cooling block = -14 degC
