Fission chamber detector
WebJul 19, 2024 · The use of the fission chamber with post-activation measurements has provided absolute fission product yield data with minimal uncertainties. Conclusion: The photon-induced cumulative fission product yields of U 235, U 238, and Pu 239 are compared with previous photon- and neutron-induced fission measurements. In the near … WebThe detector consists of an ionization chamber with several thin deposits of fissionable material. The ionization chamber is thin enough that it does not significantly affect the neutron beam and may be left in the neutron flight path during experimental measurements to continuously monitor the beam flux.
