Abstract:
There is provided a glow discharge mass spectroscope having a higher analytical sensitivity by increasing an amount of extracted ion beams without a significant change in device construction and drive conditions of conventional glow discharge systems. When glow discharge is generated in a discharge region  27 , an amount of ion beams extracted by a magnetic field formed by a first magnet  15  and a second magnet  26  is increased by disposing the circular and flat plate-shaped first magnet  15  between a flat plate-shaped solid sample  30  and a plunger  16  for holding the solid sample  30 , disposing the ring-shaped second magnet  26  disposed coaxially with the first magnet  15  so as to surround a discharge region  27  at an ion extraction port side of a cell body  21  that forms the discharge region  27 , and disposing the first magnet  15  and the second magnet  26  so that magnetization directions are parallel to each other in a direction toward the ion extraction port from the opening and magnetic poles are opposite to each other.

Claim (Index 1):
A glow discharge system used for a glow discharge mass spectroscope, the glow discharge system comprising:\n a sample holder that has an opening, and includes a holding member holding a flat plate-shaped solid sample with a main surface facing the opening, from a side opposite to the opening; and a discharge cell that is adjacent to the opening side of the sample holder, and has an ion extraction port positioned at a side opposite to the opening, and forms a discharge region, wherein a circular and flat plate-shaped first magnet is provided on a side where the holding member holds the solid sample; a ring-shaped second magnet that is embedded in the discharge cell so as to surround the discharge region and is disposed coaxially with the first magnet is provided on a side of the ion extraction port of the discharge region; and the first and second magnets are disposed so that magnetization directions are parallel to each other in a direction toward the ion extraction port from the opening and magnetic poles of the first and second magnets repel each other.
