Total Dose and Dose Rate Effects on Some Current Semiconducting Devices

Applicator Attenuation Effect on Dose Calculations of Esophageal High-Dose Rate Brachytherapy Using EDR2 Film

Introduction Interaluminal brachytherapy is one of the important methods of esophageal cancer treatment. The effect of applicator attenuation is not considered in dose calculation method released by AAPM-TG43. In this study, the effect of High-Dose Rate (HDR) brachytherapy esophageal applicator on dose distribution was surveyed in HDR brachytherapy. Materials and Methods A cylindrical PMMA phan...

A systematic method for simulating total ionizing dose effects using the finite elements method

Simulation of total ionizing dose effects in field isolation of FET technologies requires transport mechanisms in the oxide to be considered. In this work, carrier transport and trapping in thick oxides using the finite elements method in the Synopsys Sentaurus platform are systematically simulated. Carriers are generated in the oxide and are transported out through a direct contact with the ga...

Total Dose Effects on RHbip1 technology

This Chapter deals with two tests we performed on our wafers in order to evaluate the total dose response of RHbip1 technology. The practical aim was to establish the reliability of the voltage regulator in an LHC-like radiation environment. Moreover irradiation data for test structures were also taken and analyzed, in order to get more into the damage physics. We made tests with neutrons and p...

Effects of Kilovoltage on Image Quality and Entrance Surface Dose in Lumbar Spine Digital Radiography

Introduction: Digital radiography possesses a wide dynamic range and has a major advantage in producing an acceptable image of diagnostic value even though overexposure occurs. Lumbar spine (LS) radiography is the most common examinations that gives high radiation dose to patients and accounts for the highest collective population dose of any conventional radiographic ...
