  abstract     = {{While developing stable and re-accelerated rare isotope beams (RIB) for acceleration with the TAMU K500 cyclotron, a background of various stable beams has been observed. It has been determined that this background is arising from alloys and contamination in the components of our ECR ion sources, in particular, the aluminum alloy plasma chamber. We have developed a detector system based on diamond detector telescopes that allows us to measure the composition of the beam after acceleration with the K500 cyclotron at TAMU. Using this technique, we have been able to develop ion source and cyclotron tuning methods to minimize the stable beam background and maximize the stable beams of interest and/or the RIBs. We also endeavor to reduce the stable beam background from the ECR ion sources using techniques such as pure aluminum liners. In my presentation, I plan to show our accelerated beam detection setup with diamond detectors. I also plan to present about the background we have measured with this setup from the ECRIS components, in particular, the plasma chamber. Finally, I will comment on our efforts to reduce this background.}},
