End loss analyzer system for measurements of plasma flux at the C-2U divertor electrode
August 2016 | M. E. Griswold | Review of Scientific Instruments | Paper
An end loss analyzer system consisting of electrostatic, gridded retarding-potential analyzers and pyroelectric crystal bolometers was developed to characterize the plasma loss along open field lines to the divertors of C-2U. The system measures the current and energy distribution of escaping ions as well as the total power flux to enable calculation of the energy lost per escaping electron/ion pair.
