An online eminent scientist session was conducted on 09 October 2020 by Prof (Dr.) R G Sharma moderated by Dean, SOBAS, Prof (Dr.) Ram Krishna Thakur. Prof. Ram Krishna Thakur firstly introduced the speaker and warmly welcomed him for conducting the session. Prof. R G Sharma is one of the best known scientist in the country with 56 years of experience in the field of Low Temperature Physics, Superconductivity, Superconducting Magnets and Cryogenics. Dr. Sharma firstly introduced the concept of a superconductor as having zero resistance when cooled below a critical temperature Tc, a few degrees above absolute zero. Besides, a superconductor is also a perfect diamagnet and thus not allow a magnetic field to enter it. Maximum use of superconductor has been made in building magnets producing small field to as high as 45.5 T field. He explained some very interesting aspects of superconductors such as superconducting magnets have been the backbone of powerful particle accelerators like the LHC (large hadron collider) at CERN which led to the discovery of the illusive Higgs Boson. Modern whole body MRI (Magnetic Resonance Imaging) scanners use (1.5/3T) superconducting magnet because a current can flow in a superconducting magnet persistently forever without the power supply, if only the magnet terminals are shorted after energizing the magnet.

This leads to unprecedented field stability which is a primary requirement of an MRI magnet. Superconductivity thus serves the humanity at large, MRI being a most common diagnostic tool with the radiologists in hospitals. Fusion reactors, which create the Sun in the laboratory, are being built in several countries and through international efforts to produce clean electric power beyond 2040. Huge superconducting magnets are also mandated in these machines to contain hot plasma in Tokamak configuration. Overall participants attended the session were nearly 100 from across the country comprising of researchers, teachers and UG, PG students. The session was finally concluded with a vote of thanks from moderator, extending his appreciation to the speaker and all the participants.
