Abstract

In an effort to obtain information about the acceleration of heavy ions in tandem accelerators, the charge state distribution of oxygen ions accelerated in the University of Washington FN tandem accelerator was measured at three terminal voltages and over a range of stripper pressures. It is found that the stripper pressure normally used is below the value required for equilibrium in the charge exchange process, but that at higher terminal voltages the average charge state of the ions can rise above the equilibrium value due to focusing effects in the accelerating tubes. This phenomenon has implications in the use of foil strippers with heavy ion beams. A useful empirical relation for the optimum stripper pressure for a given charge state is obtained.
