Beam pulsing by means of a grid electrode fitted outside the source canal is described. Pulsed beams of the width up to 0.2μs are obtained. The wave form of the pulsed beam is similar to that of the applied voltage pulse. The same result is obtained in the case of einzel lens where voltage modulation is applied to the electrode which is usually grounded.
