Results derived from calculations based on a one-dimensional ballistic model are presented to indicate the extent to which a current pulse of 150-keV electrons containing 1 ..mu..C of charge and having a duration of 15 nsec (FWHM) can be bunched by a combination of accelerating and decelerating voltage gaps followed by a drift space. To be useful, the bunched current must be accelerated by an existing accelerator (ORELA), so the calculated results include estimates (upper and lower limits) of the fraction of the bunched beam that will be accelerated. It is found that with 8 voltage gaps the 15-nsec (FWHM) pulse can be reduced to a pulse of approximately 4 nsec (FWHM) in a length approximately 400 cm and that approximately 50% of this bunched pulse will be accelerated by ORELA. The fraction of the bunched pulse that will be accelerated is approximately the same as that for an unbunched pulse.
