Abstract:
The p-MOSFET dosimeter studied in this work has been manufactured at LAAS- CNRS Laboratory in Toulouse France, for applications in personal and space dosimetry. They are proposed for proton, heavy ions and electron and photon dose measurements. The current study investigates the sensitivity of this new type of Metal-Oxide-Semiconductor field effect transistor (MOSFET) to electrons. The sensitivity of the new MOSFET based dosemeters to electrons is linear for wide dose ranges. The influence of the electrons energy on the dosemeters response is also investigated.

Abstract:
Radiation Sensitive MOSFETs (RADFETs) have been commonly used as ionizing radiation dosimeters. The threshold voltage variation is the main transistor parameter used for radiation dosimetry, as this voltage variation is directly related to total dose and it can be easily determined by using simple measurement and biasing circuits. In this work it is presented a novel experimental method to determine the optimal drain-source current value to be supplied to a p-type MOSFET used in a traditional RADFET configuration (diode connected transistor) for monitoring of the accumulated X- and gamma-radia

Abstract:
Investigation of Al-gate p-channel MOSFETs sensitivity following irradiation using 200 and 280 kV X-ray beams as well as gamma-ray irradiation of 60Co in the dose range from 1 to 5 Gy was performed in this paper. The response followed on the basis of threshold voltage shift and was studied as a function of absorbed dose. It was shown that the most significant change in threshold voltage was in the case of MOSFET irradiation in X-ray fields of 200 kV and when the gate voltage was +5 V. For practical applications in dosimetry, the sensitivity of the investigated MOSFETs was also satisfactory for

Abstract:
A new dosemeter based on a depleted Metal-Oxide-Semiconductor field effect transistor, sensitive to both neutrons and gamma radiation was manufactured at LAAS-CNRS Laboratory, Toulouse France. In order to be used for neutron dosimetry a thin film of lithium fluoride was deposited on the surface of the gate of the device. The characteristics of the dosemeter such as its response to neutron dose were investigated. The response in thermal neutrons was found to be high. In fast neutrons the response was lower than that of thermal neutrons but higher than the one presented in literature.

Abstract:
It is known that the device MOSFET works as a dosimeter in radiation beams for cancer radiotherapy. Basically, the radiation beam generates defects in a way that produces in the MOSFET the variation in its threshold voltage, VT, which is proportional to the accumulated radiation dose. Recently, MOSFETs were also tested under X-ray beams commonly used in the energy range applied to medical diagnoses, which is lower energy than radiotherapy. Indeed, it was already shown that the MOSFET drain current varies with the radiation dose for energies in the range applied to diagnostic radiology. In this

Abstract:
A commercial pMOS transistor (MOSFET), 3N163 from Vishay (USA), has been characterized as a low-energy proton beam dosimeter. The top of the samples’ housing has been removed to guarantee that protons reached the sensitive area, that is, the silicon die. Irradiations took place at the National Accelerator Centre (Seville, Spain). During irradiations, the transistors were biased to improve the sensitivity, and the silicon temperature was monitored activating the parasitic diode of the MOSFET. Bias voltages of 0, 1, 5, and 10 V were applied to four sets of three transistors, obtaining an average

Abstract Radiation detectors have two main detection mechanisms: direct conversion, which utilises a photoconductor to directly convert radiation into an electrical signal, and indirect conversion, which utilises a scintillator to convert radiation into visible light, which is subsequently converted into an electrical signal. The photoconductor material, mercury (II) iodide (HgI2) sensitive to visible light, has the property of gradually decreasing signal for repeated irradiation beams. Therefore, this study aimed to improve the signal magnitude and stability to repeated measurements of polycr
