    Abstract: A high-voltage power source for applying high voltage to a nozzle of an ESI ion source includes a charge release assistant section (26) including switch circuits (62 and 65) and other elements for forcing electric charges accumulated at output terminals to be discharged in a polarity-switching operation, whereby the positive/negative switching of the polarity of the output voltage can be quickly performed. In the mass spectrometer according to the present invention, for example, when the voltage applied to the nozzle needs to be changed from V 1 to V 2 (where V 1 and V 2 are positive, and V 1 >V 2 ), a voltage control section (20) under the command of a main controller (9) operates a positive voltage generation section (21) and negative voltage generation section (23) so as to temporarily provide a negative output voltage. After a predetermined period of time, the voltage control section operates the positive voltage generation section (21) and negative voltage generation section (23) so as to provide voltage V 2 . If the voltage was simply changed from V 1 to V 2 , the voltage would decrease slowly and require considerable time for the change. The positive/negative switching of the polarity induces the discharging of the electric charges accumulated at the output terminals, and consequently, the voltage-switching operation from V 1 to V 2 is quickly performed.

    Abstract: A charged particle trap for trapping of a plurality of charged particles, and a method of operating said trap. The trap includes first and second electrode mirrors (2,3) having a common optical axis (4), the mirrors being arranged in alignment at two extremities thereof. The mirrors are capable, when voltage is applied thereto, of creating respective electric fields defined by key field parameters. The electric fields are configured to reflect charged particles causing their oscillation between the mirrors. The method includes introducing into the trap, along the optical axis, the plurality of charged particles as a beam (10) having pre-determined key beam parameters. The method further includes choosing the key field parameters for at least one of the mirrors such as to induce bunching among charged particles in the beam.

    Abstract: The invention relates to an electron beam generator consisting of a cathode (1), and anode (3) with an anode drilling for the electron beam (6) along a beam axis (5) and a Wehnelt electrode (2) arranged between the cathode (1) and the anode (3), where the cathode (1), the anode (3) and the Wehnelt electrode (2) are in a vacuum chamber. The cathode (1) and the Wehnelt electrode (2) can move perpendicularly to the beam axis (5) and in the vicinity of the cathode (1) there is a magnetic cathode protection device (7) which generates a static transverse magnetic field (9) running perpendicularly to the beam axis (5). The magnetic field (9) diverts the electron beam (6) from the beam axis (5), whereby the cathode (1) and the Wehnelt electrode (2) are shifted against the direction of deflection of the electron beam (6) and/or the direction of deflection of the electron beam (6) is selected such that the deflected electron beam (6) once more runs in the beam axis (5) in the region of the anode (3). This arrangement reduces the number of ions impinging on the cathode (1) and formed by the ionisation of residual molecules and thus advantageously lengthens the useful life of the cathode (1).
