Overview of Cryogens Production and Automation in Cryo-distribution at TIFR, Mumbai

Low temperature facility (LTF) of Tata Institute of Fundamental Research, (TIFR) Mumbai, India has been operating and maintaining helium liquefiers, nitrogen generators for more than five decades. LTF is one of the largest cryogenic facilities in India under the R&D Sectors. Cryogens being produced and dispensed to about 45 research laboratories within TIFR including some critical cryogen-using setups, magnetometer facility, homemade setups, various departments such as Nuclear and Atomic Physics, Chemical Sciences, Biological Sciences too use cryogens in a large quantities. In order to fulfill the above large cryogens demand and to maintain the supply in an uninterrupted manner, LTF implemented various automation in terms of cryogen distribution, Dewar tracking, reporting, etc. The paper will present our experience, architecture, methodology adopted, and automation implemented in the cryo-distribution at TIFR along with the proposed work.
