Transport analysis of high radiation and high density plasmas in the ASDEX Upgrade tokamak

Future fusion reactors, foreseen in the “European road map” such as DEMO, will operate under more demanding conditions compared to present devices. They will require high divertor and core radiation by impurity seeding to reduce heat loads on divertor target plates. In addition, DEMO will have to work at high core densities to reach adequate fusion performance. The performance of fusion reactors depends on three essential parameters: temperature, density and energy confinement time. The latter characterizes the loss rate due to both radiation and transport processes. The DEMO foreseen scenarios described above were not investigated so far, but are now addressed at the ASDEX Upgrade tokamak. In this work we present the transport analysis of such scenarios.

First data from CUORE-0

AbstractCUORE-0 is an experiment built to test and demonstrate the performance of the upcoming CUORE experiment. Com- posed of 52 TeO2 bolometers of 750g each, it is expected to reach a sensitivity to the 0νββ half-life of 130Te around 3 · 1024 y in one year of live time. We present the first data, corresponding to an exposure of 7.1kg y. An analysis of the background indicates that the CUORE sensitivity goal is within reach, validating our techniques to reduce the α radioactivity of the detector
