我们开发了一个质谱仪与一个新的质量分离机制，使用两个旋转电场（REF）。该质谱仪实现了宽质量范围的连续分离离子束。原则上，它对质量范围没有限制。它可以稳定运行，用于高质量离子的检测。为了评估质量分离能力，我们直接将由两个参考离子组成的质谱仪引入到Ga聚焦离子束柱。Ga同位素的质谱是通过扫描参考频率获得的。Ga同位素的峰在质谱上被清楚地分离。[DOI：10.1380/ejssnt.2016.161]
We developed a mass spectrometer with a novel mass-separation mechanism using two rotating electric fields (REFs). This mass spectrometer realizes a wide mass range with the continuous separation of ion beams. In principle, it has no limitation on the mass range. It can be operated stably for the detection of high-mass ions. To estimate the mass-separation ability, we directly introduced the mass spectrometer, which consists of two REFs, to a Ga focused ion beam column. The mass spectra of Ga isotopes were obtained by sweeping the frequencies of the REFs. The peaks of the Ga isotopes were clearly separated on the mass spectra. [DOI: 10.1380/ejssnt.2016.161]
