Claim Text:
1. A magnetic measurement system comprising: an array of gas cells that are each formed of a material having light transmissivity and being filled with alkali metal gas, the array of gas cells being entirely peripherally surrounded by a dummy gas cell that communicates with each of the gas cells of the array through a hole formed in each gas cell of the array, the through holes of adjacent gas cells of the array being co-axially aligned; and a light radiation unit, the light radiation unit configured to irradiate a light onto each of the gas cells of the array, wherein each gas cell of the array includes inner glass wall surfaces being coated with a first coating layer and a second coating layer; the first coating layer includes methyltrichlorosilane that is chemically bonded to the inner glass wall surfaces of each gas cell of the array; and the second coating layer includes non-polar second molecules, which are physically adsorbed to the silane.
