摘要:PURPOSE:To reduce variance in measurement nsitivity by arranging a cylindrical spiral, or cage-shaped auxiliary electrode outside a grid and a filament. CONSTITUTION:An ion collector 13 which extends into a glass pipe 11 having an opening part in its side part from atop is provided in the glass pipe 11. The spiral grid 14 is provided outside the ion collector 13 and the filament 15 is arranged nearby the grid 14. Further, the cylindrical auxiliary electrode 16 is arranged outside the grid 14 and filament 15. Thus, the cylindrical auxiliary electrode 16 is arranged outside the grid 14 and filament 15, so the majority of ions generated outside the grid 14 are entered into the auxiliary electrode 16 and variance in measurement nsitivity is reduced almost to variance of a triode type.
