| Research Abstract |
We directly measured for the first time particle heating and acceleration of magnetic reconnection using short-pulse/high magnetic field merging experiment and 2-D image diagnostics of magnetic field, ion temperature and electron temperature. We found plasma acceleration to 70-80% of Alfven speed by reconnection outflow, selective ion heating by fast shock at two down-stream of reconnection outflow and electron heating by ohmic heating of current sheet.
