The EDELWEISS Dark Matter search programme for 2017 and beyond — •Klaus Eitel for the EDELWEISS collaboration — Karlsruher Institut für Technologie, Institut für Kernphysik, Postfach 3640, 76021 Karlsruhe

Starting from the achieved sensitivity of EDELWEISS-III with its FID800 Ge detector technology, we present the planning for the next measurement phase. This will concentrate on the usage of Ge bolometers with voltage-assisted amplified heat signals (so-called Neganov-Luke mode) to explore the parameter space for low mass WIMPs (down to m~1GeV). Significant improvements in sensitivity can be realised with a moderate exposure of 350 kg.d within the next 2 years. Beyond 2017, the already existing cooperation with SuperCDMS should lead to a common experimental infrastructure in SNOLAB.

Current R&D activities, sensitivity projections and the project towards the SNOLAB cryogenic facility will be presented.
