Project: MicronOrigami_gross 
Subject: run ATTENTION: wrong bias voltage 
Run Number: run011 
Events: 150k 
StartTime: 16.10.2012 05:19:28  
EndTime: 16.10.2012 09:59:24 
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#3 ->  left side of sensor -> wide side of wedge sensors

Position of xy table:
x = 83, 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 = -16 degC
Wedge old: Out = -15 degC, cooling block = -15 degC

 

Stopped after 132658 events, because of empty gas bottle and thus insufficient cooling.
