Abstract

PURPOSE: To obtain a detector suitable for detecting meta-stable ion, by locating ion detector and β slit alternatively at optimal position in the proximity of intermediate focus point between electric and magnetic fields.
CONSTITUTION: The ion detector 1 is entirely secured through insulative support 3 to the cylinder 14, while the shield box 4 surrounding the ion detector 1 is secured through insulative supporter 18 to the cylinder 14. A slit 5 is provided at the tip of shield box 4, and said integrally constructed ion detector 1, shield box 4, cylinder 14, etc. is slidably set in vacuum container constructed with electric field case 10 having inner field electrode, analyzer tube 8 having outer electromagnet 9 and flange 12. Consequently the detector and the slit can be switched to intermediate focus point, thereby the measurement can be performed without deteriorating the sensitivity.
