Recently, the facilities of radioactive ion beam (RIB) combined with advanced detector systems provide us unique opportunity to probe the exotic properties of the nuclei with unusual neutron-to-proton ratio. In this article, a study of characterization of different types of ultra-fast timing detectors: a special type of gas detector (multi-strip multi-gap resistive plate chamber, MMRPC) ($sigma$ $<$100 ps), scintillators array ( viz., $LaBr_3:Ce$) (timing resolution ($sigma<$250 ps) are being presented. A brief discussion on usage of these different types of ultra-fast timing detector systems at radioactive ion beam facilities is also included.
