Production method of gas cell, and gas cell

摘要

A production method of a gas cell includes: forming a coating layer on a surface of a plate material; assembling a plurality of the plate materials having the coating layer formed thereon so as to form a cell surrounded by the surface having the coating layer formed thereon; and filling the formed cell with an alkali metal gas.

1. A production method of a gas cell array for a biomagnetism measuring apparatus, the production method comprising:
forming a coating layer on surfaces of a plurality of light transmissible plates including first through third plates; assembling the plurality of light transmissible plates to form the gas cell array including first through third cells that are laterally surrounded by the first plate on which the coating layer is formed, the first through third cells being formed on a same plane, the second plate being configured as a lower surface of the first through third cells; providing a first through-hole between the first cell and the third cell so as to have gas communication therebetween; providing a second through-hole between the second cell and the third cell so as to have gas communication therebetween; accommodating an ampoule, in which an alkali metal solid is sealed, in the third cell; placing the gas cell array in an inert gas atmosphere and sealing an upper surface of the first through third cells by the third plate so that the gas cell array is sealed by the first through third plates; and breaking the ampoule to fill the first through third cells with alkali metal atoms, wherein the coating layer is either of hydrocarbon and an organic silicon compound, and the third cell laterally sounds the first and second cells, wherein the gas cell array has a fourth cell and a fifth cell, and a cell group including the first through fifth cells is two-dimensionally disposed on the same plane.
