Description

A radiation-resistant detector system based on metal microstrip detectors for two-dimensional monitoring and measurement of the spatial distribution of the intensity of electron and hadron beams at the accelerators of the Institute of Nuclear Physics IN2P3 (Orsay) was developed and manufactured according to the physical and technical characteristics agreed with the French side. Within the framework of the proposed project, a system of matrix modular metal collimators has been developed for the formation of a fractionated dose field, which will allow to improve the methods of spatially fractionated radiation therapy, namely, to generate a minimum of secondary radiation from the collimator and ensure the maximum possible PVDR. Special beam profilometers based on metal microstrip detectors were developed to monitor spatially fractionated (multibeam) radiation. This provides an appropriate level of safety and helps avoid over-exposure to the patient. According to the results of computer simulation, the optimal materials and geometry of the collimators were determined. In particular, copper, tantalum and tungsten turned out to be the best materials for protons. When the thickness of the collimator is twice the length of the beam path in the body of the collimator, the collimator itself ensures complete absorption of the secondary radiation. Research results were presented at scientific seminars of the high-energy physics department of the National Academy of Sciences of Ukraine, at joint working meetings with IN2P3 (Orsay) employees in online ZOOM video conference mode, as well as in presentations at scientific conferences.
