    Abstract: 本发明提供一种电磁辐射源,利用电子枪产生环形电子注,利用靠近电子枪一侧的第一光栅使所述电子枪产生的环形电子注产生预群聚,利用靠近与电子枪对应的收集极一侧的第二光栅使群聚的电子团产生相干的特异史密斯‑帕赛尔(Smith‑Purcell)辐射,辐射频率为电子团群聚频率的5到6倍,该辐射频率在太赫兹频段,特异史密斯‑帕赛尔辐射的电磁辐射强度比普通史密斯‑帕赛尔辐射强度高一到两个数量级,因而利用该方法能够产生具有高辐射频率和高辐射强度的太赫兹频段的电磁波。

    Abstract: A method of transporting gas and entrained ions between higher and lower pressure regions of a mass spectrometer comprises providing an ion transfer conduit 60 between the higher and lower pressure regions. The ion transfer conduit 60 includes an electrode assembly 300 which defines an ion transfer channel. The electrode assembly 300 has a first set of ring electrodes 305 of a first width D1, and a second set of ring electrodes of a second width D2 (=D1) and interleaved with the first ring electrodes 305. A DC voltage of magnitude V 1 and a first polarity is supplied to the first ring electrodes 205 and a DC voltage of magnitude V 2 which may be less than or equal to the magnitude of V 1 but with an opposed polarity is applied to the second ring electrodes 310. The pressure of the ion transfer conduit 60 is controlled so as to maintain viscous flow of gas and ions within the ion transfer channel.

    Abstract: An electro-optical (EO) radiation collector for collecting and/or transmitting EO radiation (which may include EO radiation in the visible wavelengths) for transmission to an EO sensor EO radiation collector may be used with an arc flash detection device or other protective system, such as an intelligent electronic device. The arc flash detection device may detect an arc flash event based upon EO radiation collected by and/or transmitted from the EO radiation collector EO radiation collector may receive an EO conductor cable an end of which may be configured to receive EO radiation. A portion of the EO radiation received by EO radiation collector may be transmitted into the EO conductor cable and transmitted to the arc flash detection device. The EO radiation collector may be adapted to receive a second EO conductor cable, which may be used to provide redundant EO transmission and/or self-test capabilities.
