Baiev O. Computer modeling and computational methods of spectroscopy of high-current radiation sources based on absorbers method

The aim: development of computer modeling methods of radiation spectrometry, which is performed based on measuring charge deposition in absorbers with aim to make science-based decisions for developing and using hardware-software complexes of radiation spectrometry. The research object: Process of radiation spectrometry which is based on measuring charge deposition in absorbers stack. For the purpose to improve of methods for radiation energy reconstruction comparison method was developed. The method based on Monte-Carlo techniques, models of electron beam spectrum and models of process of charge in absorbers measurement which were developed in the thesis. Set of quality indicators of reconstruction of radiation energy parameters was suggested. Neural networks methods were developed for solving problem of radiation spectrum reconstruction based on results of depth-charge curve measurement. The type and topology of network, training algorithm and methods of data pre- and post-processing were defined. The recommendations were made for developing hardware-software complexes of radiation spectrometry.
