摘要： An apparatus for separating ions includes an electrode arrangement having a length extending between first and second ends. The first end is configured to introduce a beam of ions into an ion transmission space of the arrangement. An electronic controller applies an RF potential and a DC potential to an electrode of the electrode arrangement, for generating a ponderomotive RF electric field and a mass-independent DC electric field. The application of the potentials is controlled such that a ratio of the strength of the ponderomotive RF electric field to the strength of the mass-independent DC electric field varies along the length of the electrode arrangement. The generated electric field supports extraction of ions having different m/z values at respective different positions along the length of the electrode arrangement. Ions are extracted in one of increasing and decreasing sequential order of m/z ratio with increasing distance from the first end.

摘要： An ion spectrometer is provided, comprising: an ion source, arranged to generate ions continuously with a first range of mass to charge ratios; and an ion trap, arranged to receive ions from the ion source along an axis, and to eject ions with a second range of mass to charge ratios orthogonally to that axis, the second range of mass to charge ratios being narrower than the first range of mass to charge ratios. In some embodiments, ions generated by the ion source continuously flow into the ion trap. Additionally or alternatively, ion optics receive ions ejected from the ion trap and cool the ions without substantial fragmentation. An ion analyser receives ions ejected from the ion trap or ion optics and separates the ions in accordance with at least one characteristic of the ions.

摘要： A linear ion beam bonding apparatus and an array structure thereof, comprising a pair of primary radiofrequency electrodes (501 and 502) extending along the axial direction and oppositely arranged on two sides of the central axis of the linear ion beam bonding apparatus. Section patterns on different section planes of each of the primary radiofrequency electrodes (501 and 502) and perpendicular to the central axis are all kept symmetric via a primary symmetric plane (506) of the central axis. Radiofrequency voltages attached to the primary radiofrequency electrodes (501 and 502) are of identical phases. An ion extraction groove (84) is arranged on at least one of the primary radiofrequency electrodes (501 and 502), while at least one pair of auxiliary electrodes (503 and 505) are arranged on two sides of the pair of primary radiofrequency electrodes (501 and 502). The auxiliary electrodes (503 and 505) are arranged in duality to the primary symmetric plane (506). At least one of the auxiliary electrodes (503 and 505) is provided with a finite number of symmetric planes (507), while a minimal angle greater than 0 degrees and less than 90 degrees is provided between each symmetric plane (507) and the symmetric plane (506) of the primary radiofrequency electrodes (501 and 502). By means of this, a quadrupole field component of an ion beam bonding radiofrequency electric field within the ion beam bonding apparatus is strengthened.

摘要： This invention relates to a method of trapping ions and to an ion trapping assembly. In particular, the present invention has application in gas-assisted trapping of ions in an ion trap prior to a mass analysis of the ions in a mass spectrometer. The invention provides a method of trapping ions in a target ion trap of an ion trapping assembly that comprises a series of volumes arranged such that ions can traverse from one volume to the next, the volumes including the target ion trap, whereby ions are allowed to pass repeatedly through the volumes such that they also pass into and out from the target ion trap without being trapped. Potentials may be used to reflect the ions from respective ends of the ion trapping assembly. Optionally, a potential well and/or gas-assisted cooling may be used to cause the ions to settle in the target ion trap.
