Title:
超伝導トンネル接合素子を用いた光子及び放射線及び中性子の検出器、及びイメージ検出器
Document Type and Number:
Japanese Patent JP4747332
Kind Code:
B2
Abstract:
In the improved neutron image detector, MgB2 enriched in a constituent element 10B of wide energy gap is used as a neutron detection plate, which is provided at the center and the four corners with a phonon sensor comprising an insulation layer overlaid with Mg11B2 enriched in 11B of narrow energy gap in order to detect phonons resulting from the generation of alpha-rays which occurs in the detection plate upon incidence of neutrons, and sensor's signal intensity and signal propagation time are used to detect the incident position of neutrons.
