High Mach number astrophysical plasmas creates collisionless shocks via plasma instabilities that are responsible for cosmic ray acceleration. A series of laboratory experiments were conducted on Omega and the National Ignition Facility to observe: the Weibel instability; collisionless shock formation; and electron acceleration. In addition to the case of unmagnetized condition, shock formation under magnetized environment is also being studied.
