摘要: Doppler tomography is a well-known method in astrophysics to image the accretion flow, often shape of thin discs, compact binary stars. As discs rotate, all emitted line radiation Doppler-shifted. In fast-ion Dα (FIDA) spectroscopy measurements magnetically confined plasma, Dα-photons are likewise Doppler-shifted ultimately due gyration fast ions. either case, spectra emission sensitive velocity distribution emitters. Astrophysical has lead images binaries revealing bright spots, spiral structures and flow patterns. Fusion plasma led an function tokamak ASDEX Upgrade. This matched numerical simulations very well. Here we discuss achievements approach, its promise limits, analogies differences astrophysical fusion what can be learned by comparison these applications.
