An Experimental Device to Investigate Columnar Recombination Models
2022 IEEE Nuclear Science Symposium and Medical Imaging Conference (NSS/MIC)
Year: 2022 | Conference Paper |
In this paper, we discuss electron-ion recombination processes in gaseous argon with the aim to improve fission chambers models. Boag-Chabod’s model of columnar recombination is presented and its parameters detailed. The dimensioning of an experimental device to investigate this model is proposed. The specifications and the simulation of the device are presented. We conclude on the expected result...Show More
Comparison Between Silicon Carbide and Diamond for Thermal Neutron Detection at Room Temperature
O. Obraztsova;L. Ottaviani;B. Geslot;G. de Izarra;O. Palais;A. Lyoussi;W. Vervisch
Neutron radiation detector for nuclear reactor applications plays an important role in getting information about the actual neutron flux. Such a detector must be able to operate at high neutron flux levels (>109 cm-2 s-1) and discriminate the neutron and gamma responses in the nuclear reactor's mixed neutron-gamma environment. Silicon carbide and diamond are the most attractive semiconductor mater...Show More

2017 IEEE Nuclear Science Symposium and Medical Imaging Conference (NSS/MIC)
Year: 2017 | Conference Paper |
Neutron radiation detector for nuclear reactor applications plays an important role in getting information about the actual neutron yield and reactor environment. Such detector must be able to operate at high neutron flux levels (>109 n/(cm2s)) and discriminate the neutron and gammaresponses in the nuclear reactor's mixed neutron-gamma environment. Moreover such a detector must have fast and stabl...Show More

Grégory Perret;Benoit Geslot;Adrien Gruel;Patrick Blaise;Jacques Di-Salvo;Grégoire De Izarra;Christian Jammes;Mathieu Hursin;Andréas Pautz
In the framework of an international collaboration, teams of the PSI and CEA research institutes measure the critical decay constant (α0 = β/A), delayed neutron fraction (β) and generation time (A) of the Minerve reactor using the Feynman-α, Power Spectral Density and Rossi-α neutron noise measurement techniques. These measurements contribute to the experimental database of kinetic parameters used...Show More

2015 4th International Conference on Advancements in Nuclear Instrumentation Measurement Methods and their Applications (ANIMMA)
Year: 2015 | Conference Paper |
Cited by: Papers (7)
The neutron flux monitoring system of the French GEN-IV sodium-cooled fast reactor will rely on high-temperature fission chambers installed in the reactor vessel and capable of operating over a wide-range neutron flux. The definition of such a system is presented and the technological solutions are justified with the use of simulation and experimental results.Show More

2015 4th International Conference on Advancements in Nuclear Instrumentation Measurement Methods and their Applications (ANIMMA)
Year: 2015 | Conference Paper |
Cited by: Papers (5)
MINERVE is a two-zone pool type zero power reactor operated by cea (Cadarache, France). Kinetic parameters of the core (prompt neutron decay constant, delayed neutron fraction, generation time) have been recently measured using various pile noise experimental techniques, namely Feynman-α, Rossi-α and Cohn-α. Results are discussed and compared to each other's. The measurement campaign has been cond...Show More
