    • In a time of flight mass spectrometer (TOFMS) having a flight space in which ions fly in a loop orbit formed by a plurality of electric sector fields, the present invention provides a simple structure that creates a spiral path by deflecting the ions in the axial direction of the electric fields at every turn of the ions. In a mode of the present invention, the TOFMS has cylindrical electrodes 11 and 12 for creating electric sector fields E1 and E2, between which a parallel pair of planer magnetic poles 15a and 15b are provided. The planer magnetic poles 15a and 15b create a deflecting magnetic field B1 for shifting the ions in the axial direction (Y-direction) of the electric sector fields. The ions experience a Lorenz force once every turn when they pass through the deflecting magnetic field B1. This construction uses only one pair of magnetic poles facing each other across the ion path P to deflect every ion irrespective of its number of turns. There is no need to provide one deflector for each turn of the ions, as in the case of conventional TOFMSs.
    • 在具有飞行空间的飞行时间质谱仪(TOFMS)中,离子飞行在由多个电扇区形成的环轨道中,本发明提供了一种简单的结构,其通过在轴向上偏转离子而产生螺旋路径 方向的电场每转一圈的离子。 在本发明的模式中,TOFMS具有用于产生电扇区E1和E2的圆柱形电极11和12,平行的一对平面磁极15a和15b之间形成有电扇区E1和E2。 平面磁极15a和15b产生偏转磁场B1,用于使离子在电扇区的轴向(Y方向)上移位。 当离子经过偏转磁场B1时,离子经历一次洛伦茨力。 这种结构仅使一对磁极彼此跨过离子路径P,以偏转每个离子而不考虑其匝数。 对于常规TOFMS的情况,不需要为每一圈的离子提供一个偏转器。

    • The improved isotope separator comprises a vacuum vessel, a plasma generator located substantially in the center of the vacuum vessel, an electrode bounded by a hyperboloid of one sheet and a pair of electrodes bounded by a hyperboloid of two sheets, said electrodes being located within the vacuum vessel in such a way as to surround the plasma generator, a power source for supplying said electrodes with a fixed voltage and a pulsating voltage, and magnetic field generating means located outside the vacuum vessel. The apparatus is implemented by a method for isotope separation that achieves high separation factor per stage (process), that enables the process throughput to be increased with ease and which yet is applicable to the isotopic separation of many elements.

    • An ion cyclotron resonance mass spectrometer having a source region and an analyzer region operable in both the standard drift mode and in a pulsed mode which includes ion trapping. Appropriate configurations of applied electrostatic fields permit trapping of ions in the source region of the spectrometer for relatively long periods after which detection is effected by drifting the ions from the source through the analyzer region where their power absorption is measured. The spectrometer may also be operated in the normal mode, thus allowing for the full range of conventional ion cyclotron resonance measurements with the additional capability of examining the variation of ion abundance with time.
