| 20120025072 | Ion Source, And Mass Spectroscope Provided With Same - An ion source is provided with a push-out electrode, a pull-out electrode, and a pull-in electrode all for ionizing a sample and accelerating generated ions in a pulsed manner, wherein the push-out electrode and/or the pull-in electrode 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. | 02-02-2012 |
