Development of the STARK detector for nuclear reaction studies

Abstract

Silicon Telescope Array for Reaction studies in inverse Kinematics, STARK, is under development at the Center for Exotic Nuclear Studies to perform nuclear reaction experiments including elastic scattering and neutron transfer reaction. The array consists of 40 double-sided, resistive silicon strip detectors and 12 single-sided, non-resistive strip detectors, and they form three rings covering a large angular range. The expected angular resolution is less than 1°, and the angular coverage of polar angles is 43–78° and 105–150° in the lab frame. The GET (General Electronics for Time projection chamber project) electronics system is used to handle about 1000 channels from detectors. Several elastic scattering experiments are considered as the commissioning of the STARK at KoBRA in the early stage of RAON. © 2023 Elsevier B.V.
