FX-25 and FX-100 Propagation Experiments.
Abstract
Initial measurements of the hose-stable propagation pressure window and the beam current density distribution have been made using the beam produced by the FX-100 accelerator (1.5 MeV, 40 kA, and 120-ns pulsewidth). Many of the diagnostics for these measurements were developed using the beam from the FX-25 accelerator (1.5 MeV, 23 kA, and 20-ns pulsewidth). The FX-100 was decommissioned in August 1981, and the propagation experiments will continue using the beam from an accelerator (VISHNU) presently under construction for this purpose. The VISHNU beam is designed to have the same kinetic energy and current as the FX-100 beam (1.5 MeV and 40 kA), but with a much shorter pulsewidth (approx. 26 ns). Therefore, the transition to VISHNU should not involve a lengthy delay in the program, because we will be able to establish the propagation pressure window and current distribution evolution based on our experience with the FX-100 beam. We present here a brief account of the experiments performed and results obtained in the first year of this research. Following this we give the particulars of the FX-100 experiments and results, and the technical specification of the VISHNU accelerator. Details of the FX-25 experiments are to be found in App. A.
