Dj. Desimone et al., STUDIES OF A POENITZ-TYPE BLACK NEUTRON DETECTOR AS A NEUTRON-FLUX MONITOR, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 388(3), 1997, pp. 443-446
A black neutron detector of novel design has been constructed and test
ed as a neutron flux monitor. The neutron time-of-flight (TOF) techniq
ue was used to measure the zero degree neutron spectrum from a subnano
second pulsed proton beam on a thick metallic lithium target. We descr
ibe the detector, discuss the shielding arrangement and electronics, d
etermine the low-energy cut-off. We calculate the efficiency, show spe
ctra and compare measured zero degree differential cross-section of th
e Li-7(p, n(0))Be-7 reaction with recommended published cross-sections
