A series of measurements by neutron detection without and with a photon to neutron converter target were carried out … In this case no converter target is used; the neutron component is mainly produced by photonuclear interaction in the tungsten target itself. In order to enhance Mini Linatron neutron production an appropriate beryllium converter target was placed on the electron beam axis in front of the Mini Linatron and close to the tungsten-braking target. The beryllium target is a cylinder(12 cm high and 10 cm in diameter).  1, record 2, English, - converter%20target

Des photoneutrons peuvent aussi provenir de la cible de freinage elle-même. En effet, les photons créés par décélération des électrons peuvent provoquer des réactions (gamma, n) au sein même de la cible de conversion. Par conséquent, le convertisseur électron-photon, hormis un nombre atomique élevé, nécessite un seuil photoneutronique élevé et une forme métallique stable.  1, record 2, French, - cible%20de%20conversion

The possible mechanisms for the fuel rod growth such as stress-free rod growth due to fast neutron irradiation, the rod growth due to clad creep-down by the pressure difference between the rod internal gas pressure and the reactor coolant system pressure, and the rod growth due to pellet-clad mechanical interaction, have been evaluated.  1, record 3, English, - fuel%20rod%20growth

Fission chambers... [These] counters [are] designed for the detection of neutrons by their interaction with a solid fissile material... Neutrons cause fission of the fissile material and the high energy ionising products of that reaction result, usually, in the output of pulses from the chamber. These chambers are known as pulse fission chambers since the rate of pulse output is proportional to the rate of fission reactions and, therefore, to the neutron flux.  1, record 4, English, - pulse%20fission%20chamber

Chambres à fission, en régime d'impulsions. Elles ont une sensibilité faible (comprise entre 0,1 et 4 cps/nv) et délivrent des impulsions de très faible amplitude. Leur intérêt réside dans la très faible influençabilité vis-à-vis des gamma. Elles peuvent supporter jusqu'à 10₄ Gy/h.  1, record 4, French, - chambre%20%C3%A0%20fission%20en%20r%C3%A9gime%20d%27impulsions
