  We discuss how to experimentally study the symmetry breaking sector by
observing $W_L W_L \rightarrow W_L W_L$ interactions in the TeV region. We
discuss some general features of the event structure in the signal and
background events. Various tricks to enhance the signal--to--background ratio
are also presented. We show how to detect longitudinal $W$--bosons either in
the central rapidity region of the detector or in the beam pipe direction.
