  We describe the preparation of ultra cold atomic clouds in a dilution
refrigerator. The closed cycle 3He/4He cryostat was custom made to provide
optical access for laser cooling, optical manipulation and detection of atoms.
We show that the cryostat meets the requirements for cold atom experiments,
specifically in terms of operating a magneto-optical trap, magnetic traps and
magnetic transport under ultra high vacuum conditions. The presented system is
a step towards the creation of a quantum hybrid system combining ultra cold
atoms and solid state quantum devices.
