Development and testing of a three-stage double tandem accelerator-decelerator system for low energy, highly stripped ions. Progress report, March 1, 1978--February 28, 1979

Three-stage operation of the University of Pittsburgh accel-decel double tandem source of highly stripped ion beams is described. The system has produced 05+, 06+, 07+, and 08+ ions at specific energies as low as 15 keV per AMU. The design of the new decelerator tubes is discussed. The present performance and limitations of the overall system are outlined. Some new charge exchange cross sections have been measured, for combined higher ion charge states and lower ion energies than heretofore was possible. Future four-stage operation with very heavy ions is considered
