Activation Counters for Pulsed Neutron Sources.

Pagination or Media Count:
Three different types of activation counters have been tested and used for neutron diagnostics on pulsed plasmas produced with intense relativistic electron beams. Each counter employs the activation of silver, rhodium, or lead respectively. The advantages of each detector are pointed out, and limitations due to dead-time losses or neutron-scattering effects are carefully documented. Absolute calibrations have been made for radioactive sources and for dd,n3He and td,nalpha pulsed neutron sources.
