Measurements of the Coronal Acceleration Region of a Solar Flare
Abstract
The most discussed coronal hard X-ray source has been the above-the-loop-top source observed in the Masuda flare. We present new RHESSI hard X-ray observations of a similar event with simultaneous microwave observations by NoRH. These observations clearly establish the non-thermal nature of the above-the-loop-top source and triggered a new interpretation. To account for the extremely bright hard X-ray source in a rather low ambient density plasma, all electrons in the above-the-loop-top source seem to be accelerated, suggesting that the above-the-loop-top source is itself the electron acceleration region.
