More Information
Summary:The experimental results of X-ray bursts with spectral characteristics, spatial distribution, fast time variations, polarization, and directivity measurements carried out with Intercosmos, PVO/ISEE-3 spacecrafts, imaging instrument observations of Hard X-ray (HXIS) and Hard X-ray Burst Spectrometers (HXRBS) during solar maximum mission have been reviewed. The observed results about the above characteristics are discussed in detail in terms of non-thermal and thermal models. It is shown that the results can be interpreted in terms of beamed thick-target model in which electrons stream down to the loop footpoints and produce hard X-rays through electron-ion bremsstrahlung.
