Experimental method for determining the supply current of a PMOS power transistor for use as a RADFET dosimeter

چکیده
Radiation Sensitive MOSFETs (RADFETs) have been commonly used as ionizing radiation dosimeters. The threshold voltage variation is the main transistor parameter for dosimetry, this directly related to total dose and it can be easily determined by using simple measurement biasing circuits. In work presented a novel experimental method determine optimal drain-source current value supplied p-type MOSFET in traditional RADFET configuration (diode connected transistor) monitoring of accumulated X- gamma-radiation dose. Experimental results from irradiations with 60Co gamma-rays comparison measurements semiconductor analyzer indicate that lower supply values result more precise results.

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
