Production and Acceleration of Deuterium and Helium Ions

In response to the growing interest in high energy D+ and He++ ions, studies were made to determine the feasibility of accelerating these ions in the PPA. The studies indicated that in order to accelerate D+ ions to 600 MeV, the R.F. would have to operate at the 12th harmonic; to produce 2.4 GeV D+ ions, the R.F. would operate at the 8th harmonic. An attempt was successfully made to accelerate D+ at the 12th harmonic and a beam of ~6??1011D+/sec. was obtained at 600 MeV. An effort is now being made to accelerate D+ on the 8th harmonic. In addition, an attempt is being made to obtain a useful beam of He++ ions.
