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 XVI DAE-BRNS Symposium on HEP SINP, Kolkata Nov 29 - Dec 3, 2004 1
