P-Channel MOS Sensor for Measurement of Emergency Gamma and Neutron Irradiation
A dosemeter for mixed gamma-neutron fields using p-MOSDET with thick oxide has been designed and studied. A positive charge is stored in the gate oxide under ionising radiation, and threshold voltage shifts can be used to measure the gamma ray component. The basic material is high resistivity Si and...

Summary: | A dosemeter for mixed gamma-neutron fields using p-MOSDET with thick oxide has been designed and studied. A positive charge is stored in the gate oxide under ionising radiation, and threshold voltage shifts can be used to measure the gamma ray component. The basic material is high resistivity Si and changes of forward bias of drain-base or source base curves are useful to measure the fast neutron dose. The sensitivity for gamma radiation was found to be 100 mV.Gy-1, compared to that for neutron radiation, (30 mV.Gy-1. |
