The FAIR Super-Fragment-Separator (Super-FRS) facility will use a rotating graphite production target in the slow as well as in the fast extraction mode (for low-Z projectiles and intensities). A fine-grained isotropic graphite grade has been chosen due to its resistance to the thermal stress induced by high-power particle beams. Calculations based on(More)
Fission fragments from 1 A GeV 238 U ions impinging a hydrogen target are investigated by using the fragment separator FRS for magnetic selection of reaction products including ray-tracing, and ∆E-ToF techniques. On the basis of the kine-matics of the fragments, binary fission can be assigned as production process up to very heavy fragments. Fission(More)
Comparing observational abundance features with nucleosynthesis predictions of stellar evolution or explosion simulations can scrutinize two aspects: (a) the conditions in the astrophysical production site and (b) the quality of the nuclear physics input utilized. We test the abundance features of r-process nucleosynthesis calculations for the dynamical(More)
Interactions between individuals, both economic and social, are increasingly mediated by technological systems. Such platforms facilitate interactions by controlling and regularizing access, while extracting rent from users. The relatively recent idea of two-sided markets has given insights into the distinctive economic features of such arrangements,(More)
