Description
A new paradigm based on oscillations of quantum gas of conduction band electrons known as plasmons has opened unprecedented PetaVolts per meter fields [1,2,3,4]. PV/m fields can be attained using a class of non-perturbative plasmons uncovered in our work. This class of plasmons is excited by particle beams launched inside a conductive tube which makes it possible to control the excitation of large-amplitude oscillations up to the extreme limits while also mitigating various instabilities. We pursue extreme plasmons [2,5] for future high energy physics (HEP) accelerators and gamma-ray lasers through a dedicated experimental program at the SLAC national lab. The unparalleled field frontier enabled by extreme plasmons, also carries a great appeal for non-collider examinations of HEP. Our first experiments will characterize extreme plasmons in semiconductors doped to match with the FACET-II electron beam, paving the way towards broader goals outlined above.
