Existing heavy ion facilities such as the National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University rely on Electron Cyclotron Resonance (ECR) ion sources as injectors of highly charged ion beams. Long ion confinement times are necessary to produce dense populations of highly charged ions because of steadily decreasing ionization cross sections with increasing charge state. To further understand ion extraction and confinement we are using a fast sputtering technique first developed at Argonne National Laboratory [1] to introduce a small amount of uranium metal into the plasma at a well-defined time. In addition we utilize an axial x-ray apparatus [2] to characterize the hot electron plasma population via its bremsstrahlung emission.
