Neutron position detector

According to one embodiment, a neutron position detector includes a gas including a 3He gas and an additive gas. The gas has a gas composition being set so that a total of ranges of a proton and a tritium in the gas is 2.0 to 2.7 mm. The partial pressures are in an extent surrounded by a first gas c...

Zusammenfassung:According to one embodiment, a neutron position detector includes a gas including a 3He gas and an additive gas. The gas has a gas composition being set so that a total of ranges of a proton and a tritium in the gas is 2.0 to 2.7 mm. The partial pressures are in an extent surrounded by a first gas composition point of the 3He gas of 5 atm and the additive gas of 1.6 atm, a second gas composition point of the 3He gas of 5 atm and the additive gas of 2.3 atm, a third gas composition point of the 3He gas of 20 atm and the additive gas of 0.6 atm, and a fourth gas composition point of the 3He gas of 20 atm and the additive gas of 1.3 atm.
