High-energy particle colliders have revolutionized 20th century physics. Unfortunately, the collider themselves have become gargantuan and very expensive. And yet examination of the list of the most important outstanding problems in physics (1) reveals that not only will accelerator-based experiments continue to play an essential role in 21st century physics, but also that the CM energies required will be ever greater. The obvious question is, can new ideas lead to compact yet more energetic particle accelerators? I will explain how one thinks about finding a solution to this conundrum starting from first principles and demonstrate how far one such concept known as Plasma-based Accelerators has come after three decades of painstaking research.

Chan Joshi is a Distinguished Professor of Electrical Engineering at University of California Los Angeles, UCLA. He is also heads the Neptune Laboratory for Advanced Accelerator Research at UCLA.


Professor Chan Joshi is known worldwide for developing the field of plasma based particle accelerators over the past three decades. Joshi’s UCLA group was the first to conclusively demonstrate the acceleration of electrons using plasma waves. Since this demonstration, the work is now being carried out in more than 45 laboratories all over the world.


Professor Joshi is a member of the National Academy of Engineering, Fellow of the APS, IEEE and Institute of Physics (U.K.). The accelerator, plasma physics and laser communities have recognized the interdisciplinary nature of Professor Joshi’s work. He is the recipient of American Physical Society’s James Clerk Maxwell Prize (2006) and the Excellence in Plasma Physics Award (1996), USPAS prize for Achievement in Accelerator Physics and Technology (1997), 2008 Advanced Acceleration Concepts Prize and IEEE Particle Accelerator Science and Technology Award (2009). He served as APS Centennial Speaker (1999) and Distinguished Lecturer in Plasma Physics (2001). He was also awarded the Distinguished Engineering Educator Award in 2014.
