ION SOURCE, AND MASS SPECTROSCOPE PROVIDED WITH SAME |
摘要 |
An ion source (10) is provided with a push-out electrode (1), a pull-out electrode (2), and a pull-in electrode (3) all for ionizing a sample and accelerating generated ions in a pulsed manner, wherein the push-out electrode (1) and/or the pull-in electrode (3) has a curved surface shape having a depression curved in the direction opposite to the direction of travel of the ions. As a result, a compact ion source capable of temporally and spatially focusing ions and outputting the ions, and a compact time-of-flight mass spectroscope with good detection resolution and detection sensitivity which is provided with the compact ion source can be provided. |
