Recent improvements in the indigenously developed cryogenic systems at CrTD, BARC

To achieve self-sufficiency in the field of helium cryogenic systems for various departmental programs of national/international importance, in-house helium refrigeration/liquefaction systems are developed at Cryo-Technology Division (CrTD), Bhabha Atomic Research Centre (BARC), Mumbai. Due to the recent developments/improvements in the cryogenic equipment, the liquefaction rate of the indigenously developed helium liqueffer is increased from the earlier demonstrated capacity of 32 l/hr to 42 l/hr. The indigenously developed 20 K refrigeration system is modified through innovations introduced in its process in order to make it suitable for different types of client heat loads and its refrigeration capacity is increased from the earlier demonstrated capacity of 470 W at 20 K to 850 W at 17.5 K.
