Determination of the Diffusion Length of Thermal Neutrons in Graphite; DETERMINACION DE LA LONGITUD DE DIFUSION DE LOS NEUTRONES TERMICOS EN GRAFITO
Technical Report

OSTI ID:4171830
The diffusion length of thermal neutrons in graphite using the least possible quantity of material has been determined. The procedure used was the measurement in a graphite pile which has a point source of fast neutrons inside surrounded by a reflector medium (paraffin or water). The measurement was done introducing an aluminum plate between both materials and then by introducing a cadmium plate between both materials. The difference corresponds to a neutron distribution which would be obtained if on the separation surface of both medium a distributed superficial source of thermal neutrons would exist. (auth)
