Abstract
The rotating dilution refrigerator has been built up and tested to stu dy topology and dynamics of of vortices in thin helium films in porous glasses. The torsional oscillator method is considered as the basic t echnique to be used. We are able to rotate the cryostat with angular v elocity Omega up to 6.9 rad/s and resolve changes of about 0.3 mrad/s. The 40mK minimum temperature of the cryostat does not change up to ti le highest angular velocities.
