Microwave emission from flaring magnetic loops

Characteristics of the microwave emission from a flaring loop are discussed under the assumptions that (a) the magnetic energy is released into a small volume compared to the volume of the loop, and the rate at which magnetic energy is transformed into plasma energy is faster than the energy losses from the same volume; and (b) the bulk of the energy released goes into the heating of the plasma and heats primarily the electrons. A mechanism by which mildly relativistic electrons escape from the flaring loop to the upper corona is proposed.
