TRANSFORMER SCREEN Russian patent published in 2006 - IPC G01T1/20 G01N23/02 

FIELD: constructive elements of systems for non-destructive control of materials and goods by radiation methods, namely, engineering of transformers of penetrating radiations with radiation transportation and radiation transformation channels.

SUBSTANCE: in transformer screen radiation transportation channels are made in form of fiber-optic scintillator units composed of portions of filaments, scintillating in various sections of optical spectrum, channels being composed to form a packet in form of truncated cone or truncated pyramid. Filaments are connected serially or in parallel. Lesser end of transformer may be covered by additional layer of phosphor.

EFFECT: increased spatial resolution, simultaneous registration of various types of penetrating radiation: fast neutrons, and/or thermal neutrons, and/or x-ray and gamma rays.
