A 0-4 kv pulse amplifier has been constructed for field ion microscopy. The circuit employed was a triode amplifier, powered by a 5 kv full-wave voltage doubler, triggered by a General Radio 1217-B pulse generator and capacitively coupled to the field ion microscope via a 30 kv, 0.01 μF capacitor. The circuit produces either negative or positive field evaporation pulses. The usable minimum pulse time was found to be in the range 10-20 μs for this amplifier design.
