Title:
中性子検出用シンチレーター及び中性子線検出器
Document Type and Number:
Japanese Patent JP5737974
Kind Code:
B2
Abstract:
The present invention is: a neutron beam detection scintillator that comprises a colquiriite-type fluoride monocrystal containing at least one period 4 element selected from the group consisting of Ti, V, Cr, Mn, Fe, Co, Ni, Cu, and Zn, for example of the sort represented by the general formula MXMYMZF6 (MX contains Li without fail, and is Li, Na, etc.; MY is Ca, Mg, etc.; and MZ is Al, Ga, etc.), and containing at least 0.80 atom/nm3 of 6Li; and a neutron beam detection device provided with the scintillator and a photodetector. The neutron beam detection scintillator emits fluorescent light of a wavelength that silicon photodiodes have a high sensitivity towards, and the effective atomic number is comparatively small, and so it is difficult to cause light emission by means of gamma rays.
