K.C. Dr Mittal did his M.Sc (Hons) in Physics from Punjab University Chandigarh in 1974 and was selected for BARC Training School in the same year. He joined as Scientific Officer in Plasma Physics Division of BARC in 1975. He completed his Ph.D from Bombay University in 1986. The topic of his thesis was, “Generation of intense impulse gigawatt electron beam in vacuum and gas filled diodes”. During 89 to 91 he worked as a postdoctoral fellow at Cornell university USA and at University of New Mexico Albuquerque, USA. He worked as Invited Professor at University of PARIS 6 during September 91. He was again invited at Ecole Polytechnique Pallasseau during 2007. His field of research has been High Power DC, RF and impulse electron beam generation and its application in research, industry and defence. His team has developed several DC and RF electron accelerators from 500 keV to 10 MeV and up to 30 kW beam power. Many industrial applications like cross linking have been demonstated . He has more than 250 publications in journal and conferences. He has been Head Accelerator and Pulse Power Division and Project Manager Electron Beam Center, BARC and retired in May 2014
