Patent number: 10163616Abstract: A multi-reflecting time-of-flight mass spectrometer comprises a pair of parallel aligned ion mirrors and a set of periodic lenses for confining ion packets along the drift z-direction. To compensate for time-of-flight spherical aberrations T|zz created by the periodic lenses, at least one set of electrodes are disposed within the apparatus, forming an accelerating or reflecting electrostatic fields which are curved in the z-direction in order to form local negative T|zz aberration. The structure may be formed within an accelerator, within flinging fields or intentionally and locally curved fields of ion mirrors, within electrostatic sector interface, or at curved surface of ion to electron converter at the detector.Type: GrantFiled: October 23, 2014Date of Patent: December 25, 2018Assignee: LECO CorporationInventors: Anatoly N. Verenchikov, Mikhail I. Yavor

Patent number: 10141175Abstract: A multi-reflecting, time-of-flight (MR-TOF) mass spectrometer including two quasi-planar electrostatic ion mirrors extended along drill direction (Z) and formed of parallel electrodes, separated by a field free region. The MR-TOF includes a pulsed ion source to release ion packets at a small angle to X-direction which is orthogonal to the drill direction Z. Ion packets are reflected between ion mirrors and drill along the drift direction. The mirrors are arranged to provide time-of-flight focusing ion packets on the receiver. The MR-TOF mirrors provide spatial focusing M the Y-direction orthogonal to both drift direction Z and on injection direction X. In a preferred embodiment, at least one mirror has a feature providing periodic spatial focusing of ion packets in the drift Z-direction.Type: GrantFiled: August 23, 2016Date of Patent: November 27, 2018Assignee: LECO CorporationInventors: Anatoli N. Verentchikov, Mikhail I. Yavor

Patent number: 9865445Abstract: To improve spatial and energy acceptance of multi-reflecting time-of-flight, open traps, and electrostatic trap analyzers, a novel ion mirror is disclosed. Incorporation of immersion lens between ion mirrors allows reaching the fifth order time per energy focusing simultaneously with the third order time per spatial focusing including energy-spatial cross terms. Preferably the analyzer has hollow cylindrical geometry for extended flight path. The time-of-flight analyzer preferably incorporates spatially modulated ion mirror field for isochronous ion focusing in the tangential direction.Type: GrantFiled: March 14, 2013Date of Patent: January 9, 2018Assignee: LECO CorporationInventors: Anatoly N.

Patent number: 9396922Abstract: An electrostatic ion mirror is disclosed providing fifth order time-per-energy focusing. The improved ion mirror has up to 18% energy acceptance at resolving power above 100,000. Multiple sets of ion mirror parameters (shape, length, and voltage of electrodes) are disclosed. Highly isochronous fields are formed with improved (above 10%) potential penetration from at least three electrodes into a region of ion turning. Cross-term spatial-energy time-of-flight aberrations of such mirrors are further improved by elongation of electrode with attracting potential or by adding a second electrode with an attracting potential.Type: GrantFiled: October 29, 2012Date of Patent: July 19, 2016Assignee: LECO CorporationInventors: Anatoly N.
