| Zusammenfassung: | To provide a neutron position detector capable of securing a position resolution which is detection accuracy of a neutron incident position while achieving a longer service life.SOLUTION: A neutron position detector 11 comprises a tube-like envelope 20 serving as a cathode, an anode 21 arranged in a shaft center in the envelope 20, and a gas 23 containing a 3He gas and an additive gas and included in the envelope 20. The additive gas contains nitrogen as a quenching gas, and argon as a gas which shortens ranges of reaction products of a neutron and the 3He gas.SELECTED DRAWING: Figure 1
【課題】中性子の入射位置の検出精度である位置分解能を確保したまま、長寿命化できる中性子位置検出器を提供する。【解決手段】中性子位置検出器11は、陰極となる管状の外囲器20と、外囲器20内の軸心に配置された陽極21と、３Ｈｅガスおよび添加ガスを含み、外囲器20内に封入されたガス23とを備える。添加ガスは、クエンチングガスとして窒素、および、中性子と３Ｈｅガスの反応生成物の飛程を短くするガスとしてアルゴンを含む。【選択図】図１ |
