TL;DR

This paper discusses the development and characterization of ultra-fast timing detectors, such as MMRPC and LaBr3:Ce scintillators, for probing exotic nuclear properties at radioactive ion beam facilities.

Contribution

It presents the characterization of ultra-fast timing detectors, including MMRPC and LaBr3:Ce scintillators, for use in nuclear physics experiments at RIB facilities.

Findings

MMRPC detector achieves <100 ps timing resolution.

LaBr3:Ce scintillators achieve <250 ps timing resolution.

Discussion on application of these detectors at RIB facilities.

Abstract

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.
