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. An extraction plate  25  that is disposed at an ion extraction port of a discharge cell  20  and functions as an extraction electrode includes a first plate  26  that has a projection  26 a  projected toward a discharge region  27  in an opening  25 a  and that is disposed on the discharge region  27  side, and a second plate  28  that is connected to the first plate  26  in an outer circumferential edge and that is disposed with a gap provided between the first plate  26  and the second plate  28.

Claim (Index 1):
An ion extraction structure of a glow discharge system used for a glow discharge mass spectroscope, the glow discharge system comprising:\n an electroconductive cell body that forms a discharge region; an insulating member; and an electroconductive extraction plate having an ion extraction port, the extraction plate connected to the cell body with the insulating member provided between the cell body and the extraction plate, wherein the extraction plate is formed of a first plate and a second plate each having an opening, and the first plate and the second plate are connected to each other so that the openings of the first and second plates form the ion extraction port, the first plate is disposed on a side of the discharge region and has a first cylindrical projection that cylindrically projects from the ion extraction port toward the discharge region so that an inner wall of the first cylindrical projection defines the opening of the first plate, and at least one of the first plate and the second plate has a circumferential projection projecting toward the other at a circumferential portion, the first plate and the second plate are connected to each other at the circumferential projection so that a gap is provided between the first plate and the second plate, and the gap which is provided between the first plate and the second plate is arranged at opening side.
