RHESSI Instruments

The only instrument on board RHESSI was an imaging spectrometer with the ability to obtain high fidelity color movies of solar flares in X-rays and gamma rays. It uses two new complementary technologies: fine grids to modulate the solar radiation, and germanium detectors to measure the energy of each photon very precisely. See the RHESSI mission concept page and the spacecraft and instrument page for more details.
