AB  - An improved RADFET based module dosemeter has been developed by Varadis (a spin out company of Tyndall National Institute in Cork, Ireland) with serial number RM-VT01-A. The module is based on commercially available, commercial-off-the-shelf (COTS) parts and represents an updated version of its predecessor RM-VT01 with an upper dose limit of 10Gy (1 kRad) also based on COTS parts. The RM-VT01-A module was tested to a total dose of 1kGy (100 kRad) in Co60 field at Vinča Institute of Nuclear Sciences, Belgrade, Serbia. The improved module circuit was specifically designed to address the challenge of withstanding 1 kGy (100 kRad) received dose. The primary goal of this poster is to present the improvements in the circuit design and working principle. For this purpose, eleven modules were tested, 8 powered and 3 unpowered during irradiation. The module electronics accommodates both irradiation “sense” and readout “single-current-point” mode, outputting the RADFET threshold voltage (VT) as a dosimetric information, directly proportional to the absorbed dose. The output voltage of the module was measured with a simple benchtop voltmeter to demonstrate module operation simplicity and easy system integrability. The experimental data results showed excellent agreement with the dosimetry system used at the Vinca irradiation facility, and calibration data of the VT01 RadFET part.

AB  - A Metal Oxide Semiconductor (MOS) ionizing radiation detector architecture which senses trapped charge in the dielectric due to incident ionizing radiation is presented. The detector architecture increases output voltage signal as a function of trapped charge in the sensing dielectric in comparison with state of the art MOSFET (RADFET) technology. Numerical simulations were employed to help develop the device concept. It is shown that an improved voltage sensitivity is possible due to a reduction in the sensing capacitance which, unlike RADFET technology, is decoupled from the dielectric capacitance. An initial prototype of the detector has been fabricated in the silicon fabrication facility of Tyndall National Institute and irradiation experiments have been performed which confirm the improved voltage sensitivity versus commercial RADFET detectors. It is envisaged that further sensitivity increases may be possible by integrating dielectrics other than silicon dioxide.

significance of the research is reflected in the establishment of methods for achieving
the experimental characterization of the RADFET structure in ionizing radiation fields

RADFET threshold voltage on changing the absorbed dose of radiation in the dynamic
regime of the digital measuring system is used. This means that continuously the

precisely defined time intervals while the component is irradiated, which was not the
case before in the static measurement mode of change the threshold voltage. The
difference between the measured responses for two different measurement systems was
within the experimental measurement uncertainty of 2% to 5%.
