ON THE RESPONSE TO FAST NEUTRONS OF A BF$sub 3$ COUNTER IN A PARAFFIN SPHERICAL-HOLLOW MODERATOR

Journal Article · · Nucl. Instr. Methods
A system having a uniform angular response to fast neutrons was constructed which comprises a BF/sub 3/ counter placed into a hollow sphere of paraffin. The angular response was studied using a Po--Be source and found to deviate from the average by less than 2%. The system also obeys the inverse square law, behaving like a point detector with the center at the geometrical center (D.L.C.)
