  We perform a systematic scaling study of screening masses in pure gauge SU(2)
theory at temperatures above the phase transition temperature. The major finite
volume effect is seen to be spatial deconfinement. We extract the screening
masses in the infinite volume and zero lattice spacing limit. We find that
these physical results can be deduced from runs on rather coarse lattices.
Dimensional reduction is clearly seen in the spectrum.
