METHOD FOR MANUFACTURING MAGNETISM MEASUREMENT DEVICE, METHOD FOR MANUFACTURING GAS CELL, MAGNETISM MEASUREMENT DEVICE, AND GAS CELL |
摘要 |
A method for manufacturing a magnetism measurement device which measures a magnetic field generated from a living body, includes: arranging an ampoule made of borosilicate glass and having a hollow part filled with a solid alkali metal, in a void in a cell section made of quartz glass, and then sealing the cell section; and casting a pulse laser beam on the ampoule through the cell section and thus forming a penetration hole in the ampoule. The pulse laser beam has an energy of 20 μJ/pulse to 200 μJ/pulse. The absorption coefficient of quarts glass for the pulse laser beam is lower than the absorption coefficient of borosilicate glass for the pulse laser beam. |

1. A method for manufacturing a magnetism measurement device which measures a magnetic field generated from a living body, the method comprising:
arranging, in a void in a cell section made of a first glass, an ampoule made of a second glass different from the first glass and having a hollow part filled with a material, and then sealing the cell section; and casting pulse light on the ampoule through the cell section and thus forming a penetration hole in the ampoule; the pulse light having an energy of 20 μJ/pulse to 200 μJ/pulse. |
