Abstract
A helium-filled ion chamber detector for intensity measurements of hig h-intensity epithermal neutron bursts with instantaneous rates as high as 10(11) Hz is presented. This system consists of an ion chamber to detect a portion of the neutron beam, a current-to-frequency converter and CAMAC scalers to readout the chamber. The chambers and readout el ectronics have a small temperature sensitivity and have high noise imm unity. The statistical precision of the system is measured to be 10(-3 ) for each neutron beam pulse.
