A neutron detector on the basis of a boron-containing plastic scintillator

Characteristics of construction elements and investigation results of a prototype of a fast neutron detector are described. The detector prototype is based on a boron-containing molded plastic scintillator SC-331 manufactured in IHEP. The use of this scintillator for neutron detection ensures a capacity to work under high loading rates with a relatively low level of registered background events. The newly created detector may be used for neutron flux measurements in extensive air showers.
