LEBAN diagnostic for basic flaring loop parameters

The relations were analyzed between basic physical parameters in flaring loops. Based on the results of the ''Palermo Code'' hydrodynamic flare modeling, that even for transient energy input the energy deposition rate can be adequately expressed in terms of the actual maximum temperature of the plasma in the loop. Taking this into account, a simple equation was used governing the energy balance in the flaring loop. This equation relates basic characteristics such maximum temperature, mean temperature and the emission measure to the loop's length and cross section as the parameters. Except for geometry parameters, the other characteristics can be determined by soft X-ray spectral analysis. The diagnostic procedure called LEBAN (loop energy balance analysis) is described which may be helpful for deriving basic geometrical loop parameters. Palermo model calculations have been used to test reliability of the procedure. (author). 2 figs., 2 tabs., 4 refs
