Abstract
A mass spectrometry system includes a laser source, a trapping volume, first and second beam deflectors, and a deflector controller. The first and second beam deflectors are arranged on a path from the laser source to the trapping volume. The first beam deflector is configured to oscillate in a first direction at a first frequency and the second beam deflector configured to oscillate in a second direction orthogonal to the first direction at a second frequency. The deflector controller is configured to scan a scanned area within the trapping volume with the laser by controlling the oscillation of the first and second beam deflectors to cause ions trapped within the trapping volume to fragment into fragment ions. The scanned area has a first dimension defined by the oscillation in first direction and a second dimension defined by the oscillation in the second direction.
