Dr. Alok Mishra received his M.Tech. degree in Electronics Engineering from IIT-BHU, Varanasi, India, in 2012 and his Ph.D. in Electronics and Communication Engineering, specializing in RF & Microwave Engineering, from the Indian Institute of Technology, Roorkee (IIT-Roorkee), in 2023.

Since 2007, Dr. Mishra has been extensively involved in the design and development of gyrotron tubes. His work has spanned several key areas, including the fabrication and measurement of feebly tapered gyrotron interaction structures, high voltage testing of gun collector test modules, and the brazing of large collector flange and NLT flange assemblies. Additionally, he has been involved in cathode activation and the packaging of gyrotron tubes, all within the scope of a DST-sponsored project focused on a 42 GHz, 200 kW gyrotron. He is currently working on a microwave-assisted plasma discharge system and involved in the electrical and optical characterization of mercury-filled medium-pressure UV lamps, in addition to development work.

Dr. Mishra’s research interests encompass the study of ionizing and non-ionizing radiation from high-power microwave devices, particularly X-ray emission and corona discharge. He is also focused on designing electron optical systems for high-power THz/Sub-THz devices and using computational electromagnetics to understand the physics of microwave tubes.
