Varadis RADFET VT04

The critical region of the RADFET is its gate oxide. Through generation and trapping of radiation-induced charges in the gate oxide, radiation exposure changes the output voltage of the RADFET, and this change is related to the radiation dose. The RADFET response is non-linear, and a pre-recorded calibration curve is used to read the dose. The read-out is done by forcing a DC current (in the range of 10s of μA) into the Varadis RADFET VT04 and measuring the DC voltage (in the range of 5 to 9 Volts).
