Abstract
Neutron calorimeter for diagnostic support of both fission- and fusion-based pulsed neutron experiments is described. The calorimeter generates a voltage signal output via a pair of thermocouples contacting a sample material, which experiences a temperature increase due to interactions with an incident neutron fluence. Advantages of the calorimeter include the versatility derived from its small size, modularity, and the variety of employable neutron absorber materials and sizes. These characteristics permit use with neutron energies between the thermal and fast (up to 14MeV) spectra. Designoverview and requirements, Monte Carlo particle transport simulation results, test data, and possibilities for calorimeter development are provided and discussed.
