TL;DR: RHESSI as discussed by the authors is a Principal Investigator (PI) mission, where the PI is responsible for all aspects of the mission except the launch vehicle, and is designed to investigate particle acceleration and energy release in solar flares, through imaging and spectroscopy of hard X-ray/gamma-ray continua emitted by energetic electrons, and of gamma-ray lines produced by energetic ions.

TL;DR: An overview of solar flares and associated phenomena, drawing upon a wide range of observational data primarily from the RHESSI era, is presented in this paper, where the focus is on different areas of flare phenomena (footpoints and ribbons, coronal sources, relationship to coronal mass ejections) and their interconnections.

TL;DR: The Reuven Ramaty High-Energy Solar Spectroscopic Imager (RHESSI) as mentioned in this paper uses nine rotating modulation collimators that time-modulate the incident flux as the spacecraft rotates.

TL;DR: In this article, the authors reported the detection of a long (380's) giant flare from SGR 1806-20, which was much more luminous than any previous transient event observed in our Galaxy.

TL;DR: An overview of solar flares and associated phenomena, drawing upon a wide range of observational data primarily from the RHESSI era, is presented in this article, with the emphasis on the observations from multiple points of view, while bearing in mind the models that link them to each other and to theory.
