Particle accelerators which have initially been developed as a tool for basic research now have well known applications in industry, applied sciences and medical. There are more than ten thousand of accelerators running all over the world. Out of which almost fifty percent are devoted to the medical applications. The main areas of use are radioisotopes production, radiography and conventional r...
Due to the aggressive industrial development in many countries, coupled with an increase in population in some of these countries, the need exists for more advanced and effective techniques for treating wastewater. Recent efforts searching for safe and practical alternatives have resulted in the consideration of the use of irradiation with high-energy electron beams. Such an electron beam can b...
BACKGROUND The aim of the modern radiotherapy is to get a homogenous dose distribution in PTV, which is obtained by using for example physical or dynamic wedges. The using of a physical wedge has provided such isodose distributions but their use resulted in detrimental dosimetric consequences, for example beam hardening effects and practical consequences of filter handling or possible misalignm...
BACKGROUND Unscheduled accelerator downtime can negatively impact the quality of life of patients during their struggle against cancer. Currently digital data accumulated in the accelerator system is not being exploited in a systematic manner to assist in more efficient deployment of service engineering resources. The purpose of this study is to develop an effective process for detecting unexpe...
