设计了一种新型双通道飞行时间质谱仪 (D-TOFMS)，用于在光电子成像测量中选择阴离子。在该仪器中，辐射激光可以被精确触发，以与选定的离子云在一阶空间聚焦平面处重叠。与传统单通道TOFMS相比，D-TOFMS的原位质量选择性能显着提高。给出了 F- 质量选择光脱离光谱的初步实验结果，以证明该仪器的能力。 (C) 2013 AIP 出版有限责任公司。
A novel dual-channel time-of-flight mass spectrometer (D-TOFMS) has been designed to select anions in the photoelectron imaging measurements. In this instrument, the radiation laser can be triggered precisely to overlap with the selected ion cloud at the first-order space focusing plane. Compared with that of the conventional single channel TOFMS, the in situ mass selection performance of D-TOFMS is significantly improved. Preliminary experiment results are presented for the mass-selected photodetachment spectrum of F- to demonstrate the capability of the instrument. (C) 2013 AIP Publishing LLC.
