Wire chambers

We have four wire chambers, each with 128 wires in each dimension. Each is instrumented with four TDCs, reading out 64 wires each, two in each dimension.

HV information

On the test stand, labeling 1,2,3,4 from the top, the mapping is:
  • 1 -- AK
  • 2 -- AL
  • 3 -- AJ
  • 4 -- AI

This is the order they are currently in the beamline?
