Project description

LYCCA is a core detector of the HISPEC experiment within NUSTAR-FAIR. The main objective is to uniquely identify exotic nuclear reaction products by their mass A and charge Z. These nuclei are produced in nuclear reactions induced by relativistic radioactive ion beams. These beams are going to be provided by the new Super-Fragment Separator. Typical kinetic energies of the reaction products of interest are some 100-300 MeV/u, which corresponds to some 30-40% of the speed of light. The identification of the exotic nuclei is based upon event-by-event time-of-flight, energy loss (ΔE), and total energy (E) measurements, eventually in conjunction with a magnetic spectrometer. R&D and provision of the ΔE-E detector modules is the main Swedish contribution to LYCCA.
