Amit Roy International Collaborations: Large Hadron Collider, CERN Project X, Fermilab Facility for Ions and Antiprotons, GSI TESLA collaboration for SRF Development Amit Roy Major Future Projects: Radioactive Ion Beam, VECC Indian Spallation Neutron Source, RRCAT Accelerator Driven Subcritical System, BARC Free Electron Lasers, RRCAT, IUAC Amit Roy Cryogenics & Accelerators Both Linear & Cyclic Accelerators Require Highest Electric Fields , Generated by Superconducting Cavity Resonators. Require High Magnetic Fields to confine high energy particles, Superconducting Magnets generate high B fields. Amit Roy Present Scenario.....
