Kaon electro-production experiments with polarized electron beam are planed at the
Thomas Jefferson National Accelerator Facility (Virginia, USA) in order to complete the
information on polarization response functions for the kaon electro-production reactions.
The experiment uses the self analyzing property of the L
recoil. The scattered electrons will be detected in coincidence with the kaons and the
decay protons. This paper presents the simulation of this experiment which takes into
account the spectrometer acceptances, multiple scattering and radiative corrections. The
phase space distribution of the decay protons in the L
center-of-mass system are generated in order to extract information on the polarization on
the three directions. An experimental test with an unpolarized beam has been performed to
estimate the efficiency of the method.
