| 英文摘要 | 2D fast-ion velocity-space distributions have been reconstructed from two-view fast-ion D-alpha (FIDA) measurements on experimental advanced superconducting tokamak (EAST). To make up for the sparse data and incomplete velocity-space coverage with the dual-view, we use non-negativity and null-measurements as prior information to reconstruct the velocity distribution in experiments with co- and counter-current neutral beam injection. An improved reconstructed fast-ion distribution is achieved by combining the existing O- and B-port FIDA measurements with the proposed A-port FIDA view. To further improve the reliability of FIDA-based reconstructions on EAST, based on real multi-view FIDA measurements on EAST in the near future, various bases will be studied further. |
