  This article presents a new method for estimating the electron temperature of
the Protosphera's screw pinch. The temperature radial profile is obtained by a
self-consistent modeling of a 1D MHD equilibrium along with a 0D power balance
of the plasma column, given measurements and estimates of the axial pinch
plasma current, of the plasma rotational frequency and, at the equatorial
plane, of the electron density radial profile, of the edge poloidal magnetic
field, of the edge electron temperature and of the neutrals pressure in the
vacuum vessel. The plasma is considered in equilibrium with its neutral phase
and in constant rotation. A MATLAB code has been developed with the aim of
estimating the MHD radial equilibrium profiles, the thermodynamic plasma state
and the neutrals profile. The numerical estimates are compared with available
experimental data showing a good agreement.
