X-ray emission shows the existence of multi-keV electrons in low-temperature,low-power, capacitively-coupled RF-heated magnetic-mirror plasmas that alsocontain a warm (300 eV) minority electron population. Though these warmelectrons are initially passing particles, we suggest that collisionlessscattering - mu non-conservation in the static vacuum field - is responsiblefor a minority of them to persist in the mirror cell for thousands of transitsduring which time a fraction are energized to a characteristic temperature of 3keV, with some electrons reaching energies above 30 keV. A heuristic model ofthe heating by a Fermi-acceleration-like mechanism is presented, with munon-conservation in the static vacuum field as an essential feature.
