device for determining the thermal neutronenflußmultiplikation and neutronenemission

摘要

A) a device for determining the multiplication of the neutron flux and the emission of neutrons. / p & & p & b), characterized in that, in order to detect neutrons, the distance between the source of neutrons and the detector 3 of neutrons, decreased by the size of the system comprising the fissile materials, on the line which connects them, is at least 3 cm, in that the system comprising the fissile materials is, during the measurement of the thermal neutrons at approximately the middle between the source of neutrons and the detector and in that, during the measurement of epithermal neutrons, the system comprising the fissile materials lies in the vicinity of the detector. / p & & p & c) the invention relates to a device for determining the multiplication of the neutron flux and the emission of neutrons.
