Pyrolitic Boron Nitride Neutron Sensitive Direct Converter Layers

65571 High charge-state ions generated at the Electron Cyclotron Resonance Ion Source (ECRIS) offer an opportunity to study unresolved nuclear physics issues. However, there is currently a poor understanding of the exact nature of the ion confinement time, the electron-distribution-function (EDF), and the ion charge-state-distribution (CSD) inside the plasma. This project will develop a non-invasive diagnostic tool for the ECRIS to investigate ion confinement and to determine the plasma charge-state-distribution (CSD) and electron-distribution-function (EDF) for a broad variety of atomic species. In Phase I, the soft x-ray spectrum of an ECRIS will be measured and analyzed to determine EDF and internal CSD via modeling. The core plasma density and CSD will be related to the extracted beam current and CSD in order to determine the particle confinement for different ion species. A suitable diagnostic impurity emission line for high-resolution study will be identified. Commercial Applications And Other Benefits: This technology should find use in fusion research or industrial plasma devices for the maintenance of high plasma efficiencies without disrupting normal operations, and in the control or study of many plasmas such as in rare ion sources.
