Abstract
Investigation of Dosimetric Characteristics of a MOSFET Detector for Clinical Electron Beams
Highlights
It was examined to investige the dosimetric properties of metal oxide semiconductor field effect transistor (MOSFET) dedector for use in clinical dosimetry for electron energies
MOSFET has a good linearity in the range 10-500 cGy dose for electron enegies
For the 10 cGy radiation dose, MOSFET must be calibrated carefully and the calibration factor should be used in the measurements
Summary
The other measurements were made placing with the round side of the detector facing the beam on the center of the 30x30x10 cm RW3 solid phantom. Linear accelerators of this type are equipped with continuous variable trimmer systems. The collimating system of the linac is composed of the primary collimator and primary collimator of them can be mounted and which move simultaneously with the primary collimator opportunity X1, X2, Y trimmers. Dose Linearity The dose-linearity of Mosfet dedector in the range of 10 cGy-500 cGy was studied for all electron energies (Figure 3)
