Abstract: An ion implantation system has an ion source forming an ion beam. An mass analyzer defines and varies a mass analyzed beam along a beam path. A moveable mass resolving aperture assembly has a resolving aperture whose position is selectively varied in response to the variation of the beam path by the mass analyzer. A deflecting deceleration element positioned selectively deflects the beam path and selectively decelerate the mass analyzed beam. A controller selectively operates the ion implantation system in both a drift mode and decel mode. The controller passes the mass analyzed beam along a first path through the resolving aperture without deflection or deceleration in the drift mode and deflects and decelerates the beam along a second path in the decel mode. The position of the resolving aperture is selectively varied based on the variation in the beam path through the mass analyzer and the deflecting deceleration element.

Abstract: Disclosed herein is a multi-reflection mass spectrometer comprising two ion mirrors spaced apart and opposing each other in an X direction, each mirror elongated along a drift direction Y orthogonal to the direction X, and an ion injector for injecting ions as an ion beam into the space between the ion mirrors at an inclination angle to the X direction. Along a first portion of their length in the drift direction Y the ion mirrors converge with a first degree of convergence, and along a second portion of their length in the drift direction Y the ion mirrors converge with a second degree of convergence or are parallel, the first portion of their length being closer to the ion injector than the second portion and the first degree of convergence being greater than the second degree of convergence.

Abstract: Ions are injected into an orbital electrostatic trap. An ejection potential is applied to an ion storage device, to cause ions stored in the ion storage device to be ejected towards the orbital electrostatic trap. Synchronous injection potentials are applied to a central electrode of the orbital electrostatic trap and a deflector electrode associated with the orbital electrostatic trap, to cause the ions ejected from the ion storage device to be captured by the electrostatic trap such that they orbit the central electrode. Application of the ejection potential and application of the synchronous injection potentials are each started at respective different times, the difference in times being selected based on desired values of mass-to-charge ratios of ions to be captured by the orbital electrostatic trap.

Abstract: An electrostatic ion trap for mass analysis includes a first array of electrodes and a second array of electrodes, spaced from the first array of electrode. The first and second arrays of electrodes may be planar arrays formed by parallel strip electrodes or by concentric, circular or part-circular electrically conductive rings. The electrodes of the arrays are supplied with substantially the same pattern of voltage whereby the distribution of electrical potential in the space between the arrays is such as to reflect ions isochronously in a flight direction causing them to undergo periodic, oscillatory motion in the space, focused substantially mid-way between the arrays. Amplifier circuitry is used to detect image current having frequency components related to the mass-to-charge ratio of ions undergoing the periodic, oscillatory motion.

Abstract: The invention relates to the operation of trapping ion mobility spectrometers based on pushing ions by a gas flow against a counter-acting electric DC field barrier, preferably in combination with a mass analyzer as ion detector. The invention provides an additional RF ion trap upstream of the trapping ion mobility spectrometer, wherein the RF ion trap is operated as an accumulation unit in parallel with the trapping ion mobility spectrometer such that a first group of ions can be analyzed in the trapping ion mobility spectrometer while a second group of ions from an ion source are simultaneously collected in accumulation unit.

Abstract: For improving sensitivity, dynamic range, and specificity of GC-MS analysis there are disclosed embodiments of novel apparatuses based on improved characteristics of semi-open source with electron impact ionization, providing much higher brightness compared to known open EI sources. In an implementation, the source becomes compatible with multi-reflecting TOF analyzers for higher resolution analysis for improving detection limit. With improved schemes of spatial and temporal refocusing there are proposed various tandem TOF-TOF spectrometers with PSD, CID, and SID fragmentation and using either singly reflecting TOF or MR-TOF analyzers.
