Optimising neutron production from compact low energy accelerators [PDF]
, 2012 There is currently much development in accelerator based methods to provide flexible and reliable neutron generators, in response to a decline in the availability of nuclear reactors.

Data Acquisition System Prototype of the ITER Diagnostic Divertor Neutron Flux Monitor Testing at Research Nuclear Facilities [PDF]
EPJ Web of Conferences, 2021 The Divertor nuclear flux monitor (DNFM) is one of the ITER neutron diagnostics. This diagnostic consists of the three same subsystems. Each subsystem concludes the detector module with fission chambers (FCs) and the data acquisition system (DAQ).

On Controllability of Neutron Flux Distribution [PDF]
Journal of Nuclear Science and Technology, 1968 As a prerequisite to the optimal control of the neutron flux distribution of large reactors, the controllability of the flux distribution is invenstigated. The distributed parameter system is reduced to a lumped parameter system by means of truncated modal expansion. In a one dimensional reactor, any number of modes are controllable by a single control

Neutron Fluxes Underground [PDF]
Australian Journal of Physics, 1956 Eugster (1954) reported the neutron flux under 2100 m rock (5880 m water equivalent) to be 26 times that at the ground surface and suggested that radiation was coming from the centre of the Earth. An attempt has been made to confirm this interesting finding by comparing the neutron flux in the Broken Hill mines with that at ground level.

Flux measurements at the new Swiss Spallation Neutron Source SINQ
, 1998 During the initial beam tests of SINQ in December 1996 and March/April 1997, extensive flux measurements were made at the neutron guide system and at thermal beam ports, applying gold-foil activation, Gd-conversion and imaging plate radiography, time-of ...

Measurement of fluence at the D-line fast neutron facility at iThemba LABS [PDF]
, 2011 Measurements of fluence were made for the neutron beams produced at the fast neutron beam facility of iThemba LABS, using an NE213 organic liquid scintillator detector and a 238U fission ionisation chamber.

Energies, 2021 Among all the possible occurring reactivity effects of a fast reactor, the situations whereby the control rod was inserted, or the coolant was voided could lead to strong anisotropy of neutron flux distribution, therefore the angular dependence on ...

Advanced Engineering Materials, EarlyView.Mass density governs the protective behavior of oxide layers on nuclear fuel cladding. Ptychographic X‐ray computed tomography measures zirconium oxide grown on Zircaloy‐4 under reactor and autoclave conditions, revealing nearly identical bulk densities of 5.1 ± 0.80 g cm−3.

The neutron production rate measurement of an indigenously developed compact D-D neutron generator [PDF]
Nuclear Technology and Radiation Protection, 2013 One electrostatic accelerator based compact neutron generator was developed. The deuterium ions generated by the ion source were accelerated by one accelerating gap after the extraction from the ion source and bombarded to a target.
