radex13.in : High Dose Rate Radiation Detector Circuit

Requires: Victory Process/Victory Mesh/Victory Device/MixedMode/REM
Minimum Versions: Victory Process 7.30.4.R, Victory Mesh 1.4.6.R, Victory Device 1.14.1.R

This examples demonstrates High Dose Rate Effects and uses MixedMode to Demonstrate Operation of a Radiation Detector Circuit. The active device used as the radiation detector is a PiN diode incorporating a field reducing edge termination contact which is created in Victory Process in 2D mode. The PiN diode exhibits circular symmetry, so full 3D effects can be simulated using a 2D structure with cylindrical symmetry corrections.

Once the PiN diode was created, the structure is loaded into the device simulator, and SPICE circuit is included using MIXEDMODE syntax. Two greatly differing prompt dose rates of 1e8 and 1e12 Rads/second were simulated to test the versitility of the radiation detector circuit. The timing of the radiation bursts is determined by the .RAD statement in the MixedMode SPICE like syntax.

It is found that the radiation detector circuit gives a consistent detection output pulse for these two widely differing does rates and therefore total doses, validating the circuit design.
