  Collisionless shocks are common features in space and astrophysical systems
where supersonic plasma flows interact, such as in the solar wind, the
heliopause, and supernova remnants. Recent experimental capabilities and
diagnostics allow detailed laboratory investigations of high-Mach-number
shocks, which therefore can become a valuable way to understand shock dynamics
in various astrophysical environments. Using 2D particle-in-cell simulations
with a Coulomb binary collision operator, we demonstrate the mechanism for
generation of energetic electrons and experimental requirements for detecting
this process in the laboratory high-Mach-number collisionless shocks. We show
through a parameter study that electron acceleration by magnetized
collisionless shocks is feasible in laboratory experiments with laser-driven
expanding plasmas.
