Introduction:
LS-n/γ-404 series liquid scintillator detectors are composed of liquid scintillator probes, photoelectric devices, etc. The detector uses independent patented technology for neutron gamma pulse shape discrimination, which combines the charge integration method and the pulse width method, see . As shown in Figure 1, a typical example, its maximum sensitive volume can be φ6″×3″. All components of the detector (liquid scintillator, photomultiplier tube and corresponding front-end electronics) are domestically produced. The neutron gamma discrimination performance is very excellent: FOM>1@50keV.
Features:
Full metal shell design increases structural strength
Impact resistance and corrosion resistance
Transportation and storage can withstand 65 degrees high temperature
High neutron-gamma discrimination performance
High cost performance, and all structural components are domestically produced
Main applications:
Fast neutron measurement in strong gamma radiation fields
Core detection unit in the development of fast neutron dose instrumentation
Special nuclear material detection, nuclear security and anti-terrorism equipment
Fast neutron imaging
