micron baby stack
HV=100V I=11.0uA

first intcal with complete Belle stack: 2 x Origami, 2 x Micron

HV=100V  I=49uA

beam is on

chiller is set to 15°C (module temperature is ~17°C)

both Origamis and both Microns are serially cooled

  25   Tue Sep 28 22:07:16 2010 Markus FriedlBELLEcalcal002 DO NOT USE -> go to cal0038380028.09.2010 22:01:55 

Belle stack (Origami, Micron, Micron, Origami)

now cooling only for Origami, Micron are uncooled

chiller set point: -25°C, measured values on Origami: -10°C

HV=100V, Ibias=38µA, beam off

modified I2C settings for cold modules

temperature monitoring: Origami2 pipes in<->out swapped (to achieve shorter tubes)

 

PROBLEM: Origami n channels are swapped -> USE cal003 INSTEAD!!!
