Abstract

This work presents the results of testing a developed time-of-flight $\Delta E$-$E$ spectrometer designed to measure the time-of-flight (TOF) and ionization energy losses ($\Delta E$) of charged particles. The detector system makes it possible to determine the particle mass and obtain information on the charge of the registered particles. The performance of the detector system was verified using a $^{226}$Ra source and spontaneous fission fragments from a $^{252}$Cf source. The obtained results demonstrate the capability of the system to measure the parameters of both light charged particles and fission fragments produced in heavy-ion nuclear reactions. The influence of key system parameters, including detector time resolution, accuracy of energy-loss measurements, and the gas filling of the ionization chamber, on the overall resolution of the spectrometer is evaluated. The registered particle spectra are analyzed, and methodological aspects of data processing are discussed. The work is aimed at further optimization of the spectrometer and expansion of its capabilities for detailed analysis of heavy-nucleus fission products in upcoming experiments at the MAVR setup.
