International audienceThe LUMINEU project aims at developing a pilot double β decay experiment using scintillating bolometers based on ZnMoO4 crystals enriched in 100 Mo. In the next months regular deliveries of large-mass ZnMoO4 crystals are expected from the Nikolaev Institute of Inorganic Chemistry (Novosibirsk, Russia). It is therefore crucial for the LUMINEU program to test systematically and in real time these samples in terms of bolometric properties, light yield and internal radioactive contamination. In this paper we describe an aboveground cryogenic facility based on adilution refrigerator coupled to a pulse-ube cooler capable performing these measurements. A23.8g ZnMoO4 crystal was fully characterised in this setup. We show also that macro-bolometers can be operated with high signal-to-noise ratio in liquid-free dilution refrigerators
