PHASE is a new event generator dedicated to the study of Standard Modelprocesses with six fermions in the final state at the LHC. The code is intendedfor analyses of vector boson scattering, Higgs search, three gauge bosonproduction, and top physics. This first version of the program describes finalstates characterized by the presence of one neutrino, $pp\to 4q +l\nu_l$, atO($\alpha^6$). PHASE is based on a new iterative-adaptive multichanneltechnique, and employs exact leading order matrix elements. The code cangenerate unweighted events for any subset of all available final states. Theproduced parton-level events carry full information on their colour and flavourstructure, enabling the evolution of the partons into fully hadronised finalstates. An interface to hadronization packages is provided via the Les HouchesProtocol.Comment: 27 pages, Latex, 6 figure
