  Proton-driven plasma wakefield acceleration allows the transfer of energy
from a proton bunch to a trailing bunch of particles, the `witness' particles,
via plasma electrons. The AWAKE experiment at CERN is pursuing a demonstration
of this scheme using bunches of protons from the CERN SPS. Assuming continued
success of the AWAKE program, high energy electron or muon beams will become
available, opening up an extensive array of future particle physics projects
from beam dump searches for new weakly interacting particles such as Dark
Photons, to fixed target physics programs, to energy frontier electron-proton,
electron-ion, electron-positron and muon colliders.
  The time is right for the particle physics community to offer strong support
to the pursuit of this new technology as it will open up new avenues for high
energy particle physics.
