Title: ION DETECTOR ASSEMBLY
Abstract:
A mass and/or ion mobility spectrometer is disclosed comprising: an ion detector having an ion detecting surface (2) for receiving ions; ion optics for directing an ion beam (4) onto the detecting surface (2), wherein the detecting surface (2) is larger than the cross- section of the ion beam (4) at the detecting surface (2) in at least one dimension; and one or more motor (6,8) configured for moving the detecting surface (2) in said at least one dimension so that the ion beam (4) is incident on different areas of the detecting surface (2) at different times.
