    摘要: An ion source for a mass spectrometer is disclosed comprising a lens and mirror arrangement which focuses a laser beam onto the upper surface of a target substrate. The lens has an effective focal length ≦300 mm. The laser beam is directed onto the target substrate at an angle θ with respect to the perpendicular to the target substrate, wherein θ≦3°. One or more ion guides receive ions released from the target substrate and onwardly transmit the ions along an ion path which substantially bypasses the lens and mirror.

    摘要: A mass filter is disclosed comprising an orthogonal acceleration electrode 9. Ions entering the mass filter are orthogonally accelerated by the orthogonal acceleration electrode 9 in a primary acceleration region 2 and enter a flight region 3. The ions 6,7,8 are then reflected by a reflectron 4 and are directed towards an exit region of the mass filter. Ions having a desired mass to charge ratio are arranged to arrive in the primary acceleration region 2 at a time when a voltage pulse applied to the orthogonal acceleration electrode 9 falls from a maximum to zero. Ions having a desired mass to charge ratio are orthogonally decelerated such that they have a zero component of velocity in the orthogonal direction. Accordingly, ions having a desired mass to charge ratio exit the mass filter in an axial direction.
