Abstract: Determinations of plasma parameters as well as the
Magnetohydrodynamics (MHD) activity, energetic electrons energy and energy
confinement time are essential for future fusion reactors experiments and
optimized operation. Also some of the plasma information can be deduced from
these parameters, such as plasma equilibrium, stability, and MHD instabilities.
In this contribution we investigated the relation between energetic electrons,
hard x-ray emission and MHD activity in the IR-T1 Tokamak. For this purpose we
used the magnetic diagnostics and a hard x-ray spectroscopy in IR-T1 tokamak. A
hard x-ray emission is produced by collision of the runaway electrons with the
plasma particles or limiters. The mean energy was calculated from the slope of
the energy spectrum of hard x-ray photons.
