A simple Thomson parabola ion energy analyzer for intense pulsed ion beam is demonstrated. Beam ions collimated by two apertures, are deflected by a time ramping electric field and a static magnetic field. The ramping electric field is produced with a stacked cable pulser powered by a voltage divider of the pulse power generator. As there is no additional switching tube and no high-voltage generator other than the main machine, the analyzer has an electric field ramp that is coincident and has no jitter with the ion beam. A temporal history of ion beam energy is measured as an example and a reasonable agreement with the measured diode voltage is obtained.
