H8 testbeam informations

Beamfiles and Cherenkov info

All beam derived from 180GeV positive pion secondary beam.

2 Cherenkov Counters in the beam line XCET.042.519 and XCET.042.537

To set the correct pressure click "set pressure" in the "threshold status" in CESAR

Mapping of TDC Channels

Please note that the Cherenkov signals are amplified 10 times, therefore we use the same signals for both ADC and TDC

Mapping of Calorimeter Towers (Coordinates to steer beam in a specific tower)

  • H=Horizontal scale; V=Vertical scale; D=Digital value (Local control); A=Analog value (In the beam area taken by two cameras)
  • Error: 2-3 ns due to jittering
  • This is from rear end
