  Our main interest in creating a secondary high-quality KL-beam is to
investigate hyperon spectroscopy through both formation and production
processes. We propose to study two-body reactions induced by the KL-beam on the
proton target. The experiment should measure both differential cross sections
and self-analyzed polarizations of the produced $\Lambda$-, $\Sigma$-, and
$\Xi$-hyperons using the GlueX detector at the Jefferson Lab Hall D. New data
will greatly constrain partial-wave analysis and reduce model-dependent
uncertainties in the extraction of strange resonance properties, providing a
new benchmark for comparisons with QCD-inspired models and LQCD calculations.
The measurements will span c.m. $\cos\theta$ from -0.95 to 0.95 in c.m. range
above W = 1490MeV and up to 4000 MeV.
