Experimental installation based on LPMWPC and SSD detectors for registration and identification of alpha particles and fission fragments

The article describes a new detector, which is a volume filled with hexane at low pressure (3 Torr), and containing multi-wire proportional chambers and a silicon semiconductor detector. Using this setup, alpha particles emitted during the decay of the radioactive isotope ²²⁶Ra were detected. The device has an energy resolution ≤ 5% and allows measuring the ionization energy losses of alpha particles as well. Thus, the LPMWPC and SSD based experimental setup is a good tool for studying both binary and ternary fission of heavy nuclei, in which the third fragment is a high-energy alpha particle
