Technologies related to production of millikelvin temperature have been developed and tested in the laboratory. All the critical components were assembled to make a complete dilution refrigerator. The refrigerator was successfully run and commissioned in VECC. The system involves several advanced cryogenic concepts especially the capillary impedance and heat exchanger. A temperature to the tune of 50 mK has been achieved. This is the first development of its kind in India, and likely to usher a new wave in the research arena of advanced cryogenics.
