(235)~U((nth,)_f) product data measurements with correlated A, Z, KE with the UNM-SPIDER spectrometer

摘要

The UNM fission fragment spectrometer was developed as part of the SPIDER collaboration to perform fast measurement of fission fragment masses using time-of-flight and kinetic energy measurements. As part of the spectrometer development, improvements were made to the UNM spectrometer ionization chamber to allow for "active cathode" measurements. This work enabled timing from both the cathode and anode, which gives information on fragment range in the ionization gas and thus Z information. More work is being performed to gather greater statistics for comparisons with known distributions.
