Chandrashekhar Joshi is overcoming the challenges of providing smaller, more cost-effective versions of arguably the most important instrument of scientific discovery—the high-energy particle accelerator. Acknowledged as the undisputed leader in the drive to make plasma accelerators a reality, Joshi has demonstrated that charged particles can be accelerated thousands of times more rapidly using plasma compared to traditional radio-frequency-wave technology. To reduce the massive size of current machines, Joshi uses powerful laser pulses or charged particle bunches to create charged-density waves in ionized gas. The results achieved by Joshi’s plasma accelerator group have led to major national experimental facilities working toward building terra-volt-scale plasma-based particle colliders needed at the frontier of particle physics while reducing their cost.
An IEEE Fellow, Joshi is a Distinguished Chancellor’s Professor of Electrical Engineering at the University of California, Los Angeles (UCLA), Los Angeles, CA, USA.
