Assessment of fissionable material behaviour in fission chambers [PDF]

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2010
A comprehensive study is performed in order to assess the pertinence of fission chambers coated with different fissile materials for high neutron flux detection. Three neutron scenarios are proposed to study the fast component of a high neutron flux: (i)

Modeling of the saturation current of a fission chamber taking into account the distorsion of electric field due to space charge effects [PDF]

, 2002
Fission chambers were first made fifty years ago for neutron detection. At the moment, the French Atomic Energy Commission \textsf{(CEA-Cadarache)} is developing a sub-miniature fission chamber technology with a diameter of 1.5 mm working in the current ...

Accurate measurement of a fission chamber efficiency using the prompt fission neutron method [PDF]

EPJ Web of Conferences, 2017
Fission Chambers (FC) are often used to determine fission cross sections and to measure the neutron beam flux via standard neutron-induced fission reactions. Thus, the fission detection efficiency is a key parameter.

Preliminary results on the 233U capture cross section and alpha ratio measured at n_TOF (CERN) with the fission tagging technique [PDF]

EPJ Web of Conferences, 2019
233U is of key importance among the fissile nuclei in the Th-U fuel cycle. A particularity of 233U is its small neutron capture cross-section, which is on average about one order of magnitude lower than the fission cross-section.

Innovative Fission Measurements with a Time Projection Chamber [PDF]

, 2005
This study explores a pioneering idea to utilize a Time Projection Chamber (TPC) to measure fission cross sections and other fission quantities. The TPC is inherently capable of measuring fragments from fission events, decay alphas, and beam-material scatters.

THE USE OF PULSE TRANSFORMERS WITH FISSION CHAMBERS AND FISSION CHAMBER PREAMPLIFIERS

, 1957
The way in which the turns ratio of a transformer affects the gain and stabiliiy of a preamplifier utilizing transformer coupling to a matched coaxial cable is shown. In addition, the signal input to the preamplifier can be maximized by using pulse transformers to match fission chamber capacitance to the capacitance of the preamplifier input circuit ...
