An on-line system of ionization chambers for the observation of short-lived fissionable nuclei

Abstract An on-line system of six ionization chambers designed for observing short-lived spontaneously fissioning isotopes has been developed and tested. In the test experiments using an Ar ion beam spontaneous fissioning fragments from 244 Fm have been detected. It has been shown that the performance rate of the system can amount to 5 μs at a beam intensity of 0.1 μA.
