Scintillator for detecting radiation emissions from neutron generators in borehole environments comprises copolymer cross-linked with aromatic agent to form host polymer having thermoset properties

摘要

A scintillator comprises a copolymer cross-linked with an aromatic agent to form a host polymer having properties of a thermoset. The host polymer contains a primary fluorescent agent and a wavelength shifter. Independent claims are also included for: (1) a method of making a high temperature scintillation material by providing a host polymer formed of a derivative of styrene; bonding a higher melting point component to the host polymer to form a copolymer; and cross-linking by use of an aromatic compound to the copolymer; and (2) a formation characteristic-determining apparatus for a formation surrounding a borehole comprising a sonde having an elongated housing and adapted to be lowered into and moved through the borehole; a neutron source; scintillation detector(s) for measuring neutron source; and signal processor coupled to scintillator detector(s), wherein the scintillator detector and signal processor cooperate to moderate the neutron source in response to the measured neutron output.
