Abstract: A magnetic sector for charged particle beam transport that includes a magnetic field profile that achieves a linear dispersion from a collimated beam of charged particles proportional to their mass-energy-to-charge ratio. In one embodiment, the field profile necessary for the linear dispersion is obtained by the use of shaped, highly permeable poles powered by permanent magnets or electromagnetic coils.

Abstract: A spectrometer assembly comprising an ion detector array and a printed circuit board, wherein the ion detector array is attached on the printed circuit board, and the printed circuit board is secured on the same base plate that a magnetic section is secured. This configuration presents many advantages including, but not limited to, sturdy and convenient electrical connections between the assembly and following processing units, as well as mounting accuracy of the ion detector array in miscellaneous devices, and especially in front of magnetic sectors of spectrometers of the Mattauch and Herzog type. This invention pertains any types of ion detector arrays, with special emphasis to Strip Charge Detector Arrays, Faraday Cup Detector Arrays, and even more importantly to Shift Register Based Direct Ion Detection Chips.

Abstract: The present invention provides an instrument and methods for the preparative separation of components of mixtures using mass spectrometric methods. Nondestructive ionization methods are employed to generate ionized components of a mixture, the ionized components are spatially separated by mass and the mass-separated ion components are trapped. The ion source and mass spectrometric techniques employed allow the generation of large ion currents of ion components, on the order of nanoamps, which facilitate rapid accumulation of nanomole quantities of mass-separated components in relatively short times (minutes to hours).
