Preliminary results on the 233U α-ratio measurement at n_TOF [PDF]

EPJ Web of Conferences, 2020
233U is the fissile nuclei in the Th-U fuel cycle with a particularily small neutron capture cross setion which is on average about one order of magnitude lower than its fission cross section. Hence, the measurement of the 233U(n, γ) cross section relies

Calibration of CFUL01 fission chambers in the standard neutron fields of the BR1 reactor at SCK CEN [PDF]

EPJ Web of Conferences, 2021
Recent subcritical VENUS-F experiments showed that fission chambers with a threshold deposit like U-238 can essentially improve the on-line sub-criticality measurments with the beam interruption method, which is currently supposed to be the main method ...

Method to Calibrate Fission Chambers in Campbelling Mode [PDF]

IEEE Transactions on Nuclear Science, 2011
Fission chambers are neutron detectors which are widely used to instrument experimental reactors such as material testing reactors or zero power reactors. In the presence of a high level mixed gamma and neutron flux, fission chambers can be operated in Campbelling mode (also known as “fluctuation mode” or “mean square voltage mode”) to provide reliable

Application of Nonnegative Tensor Factorization for neutron-gamma discrimination of Monte Carlo simulated fission chamber’s output signals

Results in Physics, 2017
For efficient exploitation of research reactors, it is important to discern neutron flux distribution inside the reactor with the best possible precision. For this reason, fission and ionization chambers are used to measure the neutron field.

Machine learning methods for fission product identification from Bragg curves

AIP Advances, 2023
A fission time projection chamber (fission-TPC) was developed to provide precise neutron-induced fission measurements for several major actinides. As fission fragments lose energy in one of the gas volumes of the fission-TPC, energy loss information is ...
