    Abstract

    KHALA, the acronym for Korea high-resolution array of LaBr3(Ce), has been developed to measure the lifetimes of the nuclear excited states. This system consists of 36 cylindrical LaBr3(Ce) scintillator crystals with a diameter and length of 1.5 inches each. It is suitable for measuring γ-ray emission time from a few tens of picoseconds to a few tens of nanoseconds. The data acquisition electronics of KHALA are fully digitized for both energy and timing information, resulting in the quick data processing. Detailed performance specifications, such as the energy resolution, timing response, and photopeak detection efficiency, of KHALA are presented.
