A numerical algorithm for reconstructing the differential emission measure from thermally interpreted bremsstrahlung photon spectra is introduced. The method is based on the Tikhonov regularization theory for solving ill-posed in- verse problems and exploits 'ad hoc' boundary conditions to improve the restora- tion accuracy. A discussion of the...

Although both electron-ion and electron-electron bremsstrahlung contribute to the hard X-ray emission from solar flares, the latter is normally ignored. Such an omission is not justified at electron (and photon) energies above ��300 keV, and inclusion of the additional electron-electron bremsstrahlung in general makes the electron spectrum...

The Ramaty High Energy Solar Spectroscopic Imager (RHESSI ) has yielded solar flare hard X-ray spectra with unprecedented resolution, enabling reconstruction of mean source electron energy spectra F(E) by deconvolution of photon energy spectra I (). While various algorithms have been proposed, the strengths and weaknesses of each have yet to be...
