Solid-state spark chamber for detection of radiation

摘要

A combined semiconductor controlled circuit (CSCC) includes a semiconductor controlled switch (SCS). The SCS includes anode, cathode, anode gate and cathode gate terminals connected to P1 anode, N2 cathode, N1 anode gate and P2 cathode gate layers. The SCS also includes P-N junctions between P1 anode and N1 anode gate layers, N1 anode gate and P2 cathode gate layers and P2 cathode gate and N2 cathode layers. The CSCC also includes a Zener diode having a current path flowing from the cathode terminal to the anode gate terminal, a feedback resistor connecting cathode and cathode gate terminals and a substrate. A solid-state spark chamber includes a CSCC, a DC bias voltage source and an RC load having a parallel-connected load resistor and capacitor. The solid-state spark chamber also includes a plurality of measurement terminals and a ground. A method of making a solid-state spark chamber includes connecting the above components.
