Popis:	We are developing a new neutron sensitive scintillator structure designed for incorporation into digital imaging systems. Due to its internal structure and high scintillation efficiency, this new scintillator can simultaneously provide a high spatial resolution, high detection efficiency and excellent signal to noise performance. The scintillator screen consists of a microcolumnar CsI(Tl) film sandwiched between two neutron converter layers of transparent Gd-containing compounds. This paper discusses the scintillator design and characterization. Also, thermal neutron imaging performance evaluated by integrating prototype screens into a CCD camera will be outlined to demonstrate its applicability for such important applications as contraband and threat material detection.
