摘要：
A mass spectrometer is disclosed comprising a RF confinement device, a beam expander and a Time of Flight mass analyzer. The beam expander is arranged to expand an ion beam emerging from the RF confinement device so that the ion beam is expanded to a diameter of at least 3 mm in the orthogonal acceleration extraction region of the Time of Flight mass analyzer.
