In a linear ion trap, ions are confined radially by a two-dimensional radio frequency (RF) field, and axially by stopping potentials applied to end electrodes. Linear ion traps have high injection efficiencies and high ion storage capacities. ==History== One of the first linear traps was constructed in 1969, by Church who bent linear quadrupoles into closed circle and racetrack geometries and demonstrated storage of 3He+ and H+ ions for several minutes. Earlier, Drees and Paul described a circular quadrupole. However, it was used to produce and confine a plasma, not to store ions. In 1989, Prestage, Dick, and Malecki described that ions could be trapped in the linear quadrupole trap system to enhance ion-molecule reactions, thus it can be used to study spectroscopy of stored ions. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Linear ion trap」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
