Abstract
A method of aligning a light beam within a mass spectrometer includes providing precursor ions along a longitudinal axis of the mass spectrometer at two or more precursor ion locations, the precursor ion locations being spatially separated along the longitudinal axis of the mass spectrometer, the precursor ions forming in-vacuum targets. The method then includes directing a light beam from a light source in a direction along the longitudinal axis of the mass spectrometer, the light beam photo-dissociating the precursor ions, and monitoring a mass spectrometer ion signal from each of the two or more precursor ion locations while adjusting the direction of the light beam, thereby aligning the light beam within the mass spectrometer.
