  6   Thu Oct 22 08:04:51 2009 Stephan HänselSetupgeometry - silicon envelope

distance si-sledge-front to silicon-Z-center = 23 cm

-> silicon sledge front 35 cm inside from front of TPC-support at a beam position 58 cm from front of TPC-support


CCU119 = 0x77

  • position 7 = I2C16 = SiLC12 -> front X
  • position 1 = I2C17 = SiLC11 -> front Z

CCU123 = 0x7b

  • position 7 = I2C16 = SiLC01 -> back Z
  • position 1 = I2C17 = SiLC02 -> back X

  13   Mon Nov 2 13:59:09 2009 Stephan HänselSetupToDo before data-taking

in hut:

  • plug twisted pair cable from CCUM into PC (Attention - connector contains more pins, look at marks - use the most right pins when you look from the back of the PC))
  • power on CCUM in spacing behind electronic hut
  • switch on opto-electrical converter for FED (on top of PC (switch in the back) and switch on power supply (front))
  • LV on -> 01,30 and 02,60 (two times)
  • HV on -> 200V

T24/1

  • power the scintillators for triggering
  • move envelope into beamline - sledge front to sensor center is 220,5mm

-> switch on the beam
