To provide a leak detector which is configured to detect leakage by introducing hydrogen gas leaking form a test piece to an analysis tube and to provide sufficient measurement accuracy in a short time by facilitating stabilization of background and significantly reducing the time required for background recovery.SOLUTION: An analysis tube 100 provided herein comprises an ion source portion 1 for ionizing hydrogen gas introduced thereto to generate hydrogen ions, an ion collector portion 2 for detecting the amount of hydrogen ion current, and re-inflow suppression structures 71, 72, 73 for preventing hydrogen gas generated by the ions by being uncharged by the ion collector portion 2 from reflowing into the ion source portion 1.SELECTED DRAWING: Figure 5

A device and method for recording spectral information of charged particle beams, such as ion beams, or of light beams, at a high resolution. Specifically, a mass spectrometer having a focal plane detector. The device and method enable the recording of mass spectral data at both high mass resolving power and mass accuracy, during parallel acquisition of potentially the entire spectrum of a sample beam.
