Query: Comparison of Thermal Neutron Detection Efficiency of $^{6}$Li
  Scintillation Glass and $^{3}$He Gas Proportional Tube   We report on a comparison study of the $^{3}$He gas proportional tube and the
$^{6}$Li incorporated scintillation glasses on thermal neutron detection
efficiency. Both $^{3}$He and $^{6}$Li are used commonly for thermal neutron
detection because of their high neutron capture absorption coefficient. By
using a neutron source $^{252}$Cf and a paraffin moderator in an alignment
system, we can get a small beam of thermal neutrons. A flash ADC is used to
measure the thermal neutron spectrum of each detector, and the detected number
of events is determined from the spectrum, then we can calculate the detection
efficiency of different detectors. Meanwhile, the experiment have been modeled
with GEANT4 to validate the results against the Monte Carlo simulation.
