In this work, leakage radiation from EA200 series electron applicators on Siemens Primus accelerators is quantified, and its penetration ability in water and/or the shielding material Xenolite-NL established. Initially, measurement of leakage from 10 x 10 - 25 x 25 cm2 applicators was performed as a function of height along applicator and of lateral distance from applicator body. Relative to ce...

Deep level transient spectroscopy (DLTS) and minority carrier (MCTS) are used to investigate electrically active defects in commercial SiC Schottky power diodes after heavy-ion microbeam irradiation at different voltages. The DLTS MCTS spectra of pristine samples analysed compared devices showing or not signatures Single Event Leakage Current (SELC) degradation. An additional peak labelled ‘C’ ...

Introduction: Due to its simplicity, fast response and high reliability, ion chamber detectors are one of the most suitable dosimetry instruments for X and gamma rays. The dosimeter    of photon beams, which used in radiotherapy centers, requires high accuracy and should pass requirements of IEC 60731 standards. About 80 percent of the IEC 60731 standard tests such as stabil...

The gene encoding C-repeat/dehydration-responsive element binding factor 1 (CBF1/DREB1b) of Arabidopsis was introduced into rice (Oryza sativa L.) under the control of the maize ubiquitin promoter. Its incorporation and expression in transgenic rice plants were confirmed by DNA and RNA gel-blot analyses. Cold tolerance in the transgenics was not significantly different from that of the wild-typ...

This paper describes the assembly (from commercially available components) of an antilog converter, which transforms the output signals of ion-specific electrodes to ionic concentrations suitable for a linear recorder. It responds linearly to cation concentrations from 10 mum to at least 10 mm and can be used for electrodes kept at any temperatures (0 to 50 C). The leakage of K(+) from a unicel...

The objective of the investigation was to ascertain the effect of storage to the seed membrane integrity and mineral ions leakage of horse gram seed by vigour and biochemical test results on mineral composition of the seed soaked solution used for the electrical conductivity reading. Analysis revealed storage temperature has great impact to the seed coat integrity and K is the most important io...

The effects of Ti and O implantation on TiO2-x resistive switches are systemically investigated. The forming voltage drops monotonically with Ti implantation dose and forming vanishes completely at 10 ions/cm, whereas oxygen implantation causes a decrease and then increase in forming voltage. The ON/OFF current ratio becomes worse with high Ti implantation due to increased leakage currents thro...

High performance Resistive Random Access Memory (RRAM) based on HfOx has been prepared and its temperature instability has been investigated in this work. With increasing temperature, it is found that: leakage current at high resistance state increases, which can be explained by the higher density of traps inside dielectrics (related to trap-assistant tunneling), leading to a smaller On/Off rat...
