  The experiment of Ar+Au reactions at 30 MeV/u have been performed using the
Compact Spectrometer for Heavy IoN Experiments (CSHINE) in phase I. The
light-charged particles are measured by the silicon stripe telescopes in
coincidence with the fission fragments recorded by the parallel plate avalanche
counters. The distribution properties of the azimuth difference $\Delta \phi$
and the time-of-flight difference $\Delta TOF$ of the fission fragments are
presented varying the folding angles which represents the linear momentum
transfer from the projectile to the reaction system. The relative abundance of
the light charged particles in the fission events to the inclusive events is
compared as a function of the laboratory angle $\theta_{\rm lab}$ ranging from
$18^\circ$ to $60^\circ$ in various folding angle windows. The angular
evolution of the yield ratios of p/d and t/d in coincidence with fission
fragments is investigated. In a relative comparison, tritons are more
abundantly emitted at small angles, while protons are more abundant at large
angles. The angular evolution of the neutron richness of the light-charged
particles is consistent with the results obtained in previous inclusive
experiments.
