An ion spectrum analysing apparatus (1) comprising an electric field generation arrangement (3, 4, 5) which, in use, is operative to accelerate ions into a flight tube (7), and further comprising a detector (6), and recording apparatus (8) which is operative to record data representative of the spatial distribution of scattered ions impacting on the detector, and in use the recording apparatus is triggered at multiple times to record spatial distribution data relating to respective times-of-arrival of the ions. |
