ino prototype detector
INO prototype detector
  • Detector and signal specifications
    • Detector dimensions: 1m X 1m X 1m
    • 14 layers of RPCs with 6cm iron plates interleaved.
    • Two signal planes orthogonal to each other and each having 32 pick-up strips
    • Total channels = 32 X 14 X 2 = 896
    • Pulse height = 100 to 300mV; Rise time = < 1 ns
    • Pulse width = ~50ns; Rate ~ 1KHz
  • Trigger information
    • Expected trigger rate is few Hz
    • Required Trigger logic is m X n fold, where
    • m = 1 to 4; no. of consecutive channels in a layer
    • n = 5 to 1; no. of consecutive layers with m fold in each layer
    • ie m x n = (1 x 5) OR (2 x 4) OR (3 x 3) OR (4 x 2)
  • Information to be recorded on a trigger
    • Absolute arrival time of the trigger
    • Track identification (XYZ points in RPC layers)
    • Direction of track ( TDC information)
    • Miscellaneous information and calibration data
  • Monitoring health of the detector
