  We present first results of the BeppoSAX observation of the Coma Cluster.
Thanks to the unprecedented sensitivity of the PDS instrument, the source has
been detected up to ~80 keV. There is clear evidence for emission in excess to
the thermal one above ~25 keV, very likely of non-thermal origin. We have
therefore, for the first time, detected the long sought Inverse Compton
emission on CMB photons predicted in clusters, like Coma, with radio halos.
Combining X and radio observations, a value of 0.16 micro Gauss for the
volume-averaged intracluster magnetic field is derived.
