Silicon Carbide Neutron Detectors

The potential of Silicon Carbide (SiC) for use in semiconductor nuclear radiation detectors has been long recognized. In fact, the first SiC neutron detector was demonstrated more than fifty years ago (Babcock, et al., 1957; Babcock & Chang, 1963). This detector was shown to be operational in limited testing at temperatures up to 700 oC. Unfortunately, further development was limited by the poo...

Achievable accuracy in brain tumors by in vivo dosimetry with diode detectors

ABSTRACT Background: In vivo measurements of applied dose during radiotherapy treatment, is important to ensure accurate dose delivery to patients. Uncertainty in dose delivery should fall within ±5% of the prescribed dose as recommended by ICRU. Assessment of dose for radiotherapy applications performed with various types of detectors. In this study, semiconductor diodes were used which have s...

Light ions response of silicon carbide detectors 1

Silicon carbide (SiC) Schottky diodes 21 µm thick with small surfaces and high N-dopant concentration have been used to detect alpha particles and low energy light ions. In particular 12 C and 16 O beams at incident energies between 5 and 18 MeV were used. The diode active-region depletion-thickness, the linearity of the response, energy resolution and signal rise-time were measured for differe...

Entrance dose measurements for in‐vivo diode dosimetry: Comparison of correction factors for two types of commercial silicon diode detectors

Silicon diode dosimeters have been used routinely for in-vivo dosimetry. Despite their popularity, an appropriate implementation of an in-vivo dosimetry program using diode detectors remains a challenge for clinical physicists. One common approach is to relate the diode readout to the entrance dose, that is, dose to the reference depth of maximum dose such as d(max) for the 10x10 cm(2) field. V...

EPID in vivo Dosimetry

Introduction: The most modern radiotherapy devices are equipped with an Electronic Portal Imaging Device (EPID) system which is located on opposite side of the machine’s head. EPID system is often used to setting up the position verification during or between radiotherapy sessions. Material and Methods: Various types of dosimeters have been used to setting up ...
