PREDICTION OF RADIATION BEHAVIOR OF THE TWO-GATE FIELD HALL GENERATOR
Measurements of current-gate and Hall-gate characteristics of the field Hall generator in accordance with the positive bias on each gate, also in accordance with the gamma-radiation dose, were carried out. Comparison of these characteristics allowed establishing a correlation between dose and positive gate bias values responsible for equivalent changes of the sensor operating current or Hall voltage. Such correlation can form the basis for prediction of the field Hall generator radiation behavior on results of measurements of the reference sensor characteristics.
