fission chamber

fission chamber

[′fish·ən ‚chām·bər]
(nucleonics)
An ionization chamber used to detect slow neutrons; the inside wall has a thin coating of uranium, in which a slow neutron produces a fission; the resulting highly ionizing fission fragments produce a count in the chamber. Also known as fission counter.

The gamma radiations from the fission would also be comparatively low and since the fission chamber is closed except on the nozzle portions, there occurs loss of energy of many gamma radiations by collision with the wall of the chamber.
For this reason, we are concerned, in our research, with this variable which can be measured using one of the five following types of neutron detectors: Boron Trifluoride (BF3) proportional counters, Boron (10B) lined detectors, fission chamber (FC), 3He proportional counters, and self-powered neutron detectors (SPND) [1].
As an example, we are going to represent in Figures 6, 7, and 8 the results of the application of the Lee-Seung NMF algorithm [26], to a data set formed by fission chamber output signals, simulated through the Python-based simulation of fission chamber (pyFC) [29].

one neutron start-up line with a fission chamber of type Rj-1300.
The preamplifier is a fast and low-noise current preamplifier meant to be used for neutron counting systems based on He3 tubes or Fission Chambers. The goal is to have the preamplifier located in a non-radiation area, and easily accessible for maintenance purpose.
