Abstract

1,227,929. Controlling neutrons. COMMISSARIAT A L'ENERGIE ATOMIQUE 10 June, 1970 [1 July, 1969], No. 28175/70. Heading G6P. A neutron beam is collimated by the cylindrical hollow needles, 3, formed of stainless steel and internally coated with boron. The needle assembly, 2, is rotated by the motor 7 and the toothed ring 8 to prevent the shadow of the assembly 2 from being cast on the object which is irradiated. The casing, 9, is provided with cadmium lateral shielding.
