Scientific paper

In this paper we discuss the effects of different energy loss mechanisms on resulting hard X-ray and MW emission of beam electrons injected in the loop top in the corona and precipitating into loop footpoints. For this purpose we use numeric solutions of Fokker-Planck equation considering collisional and Ohmic energy losses and anisotropic scattering in converging magnetic field for different scenarios of particle injections with respect to pitch angle anisotropy and different flaring atmosphere models. Electron beam distributions obtained in collisional, collisional plus Ohmic losses, collisional plus Ohmic plus turbulent losses for the models with different magnetic convergence factors are compared. The resulting HXR and MW emission and polarisation for each models are compared and implications for the interpretation of observations are also discussed.
