Recovery time of a plasma-wakefield accelerator - Nature.com

Relaxation of a perturbed plasma back to its initial state over nanosecond timescales establishes that megahertz repetition rates are supported, and high luminosities and brilliances are in principle attainable with plasma-wakefield accelerator facilities.

Plasma generation and characterization A high-voltage discharge was used to create the plasma, ignited by a thyratron switch operating at a breakdown voltage of 25kV, supplying approximately 500A fo… [+19882 chars]
