Report of the Topical Group on Physics Beyond the Standard Model at Energy Frontier for Snowmass 2021
Tulika Bose, Antonio Boveia, Caterina Doglioni +318
This is the Snowmass2021 Energy Frontier (EF) Beyond the Standard Model (BSM) report. It combines the EF topical group reports of EF08 (Model-specific explorations), EF09 (More gen…
Report of Snowmass 21 Accelerator Frontier Topical Group 6 on Advanced Accelerators
C. Geddes, M. Hogan, P. Musumeci +1
The Snowmass 2021 Accelerator Frontier topical group \# 6 on Advanced Accelerator Concepts, covers new R\&D concepts for particle acceleration, generation, and focusing. Based on c…
Approaching Petavolts per meter plasmonics using structured semiconductors
Aakash A. Sahai, M. Golkowski, T. Katsouleas +6
A new class of strongly excited plasmonic modes that open access to unprecedented Petavolts per meter electromagnetic fields promise wide-ranging, transformative impact. These mode…
PetaVolts per meter Plasmonics: Snowmass21 White Paper
Aakash A. Sahai, Mark Golkowski, Stephen Gedney +10
Plasmonic modes offer the potential to achieve PetaVolts per meter fields, that would transform the current paradigm in collider development in addition to non-collider searches in…
Non-linear Ion-wake Excitation by Ultra-relativistic Electron Wakefields
Aakash A. Sahai, Thomas C. Katsouleas
The excitation of a non-linear ion-wake by a train of ultra-relativistic electron bubble wake [1]-[8] is modeled. The ion-wake is shown to be a driven non-linear ion-acoustic wave…
Longitudinal instabilities affecting the moving critical layer laser-plasma ion accelerators
Aakash Ajit Sahai, Thomas C. Katsouleas
In this work we analyze the longitudinal instabilities of propagating acceleration structures that are driven by a relativistically intense laser at the moving plasma critical laye…
Self-injection by trapping of plasma electrons oscillating in rising density gradient at the vacuum-plasma interface
Aakash A. Sahai, Thomas C. Katsouleas, Patric Muggli
We model the trapping of plasma within the density structures excited by a propagating energy source () in a rising plasma density gradient. Rising density grad…
Refraction of beams due to plasma lensing at a plasma-vacuum interface -- applied to beam deflection in a Copper cell with electrical RF-breakdown plasma
Aakash A. Sahai, T. C. Katsouleas
We formulate a possible description of the deflection of a relativistic beam in an inhomogeneous copper plasma, encountered by the beam when propagating through a acceleratin…
Proton acceleration by a relativistic laser frequency-chirp driven plasma snowplow
Aakash A. Sahai, T. C. Katsouleas, R. A. Bingham +4
We analyze the use of a relativistic laser pulse with a controlled frequency chirp incident on a rising plasma density gradient to drive an acceleration structure for proton and li…
Long Term Evolution of Plasma Wakefields
Aakash A. Sahai, T. C. Katsouleas, F. S. Tsung +1
We study the long-term evolution (LTE) of plasma wakefields over multiple plasma-electron periods and few plasma-ion periods, much less than a recombination time. The evolution and…
Relativistically Induced Transparency Acceleration (RITA) of Protons and Light-ions with Ultrashort Laser Interaction with Heavy-ion Plasma Density Gradient
Aakash A. Sahai, F. S. Tsung, A. R. Tableman +2
The relativistically induced transparency acceleration (RITA) scheme of proton and ion acceleration using laser-plasma interactions is introduced, modeled, and compared to the exis…
Beam loading in the nonlinear regime of plasma-based acceleration
M. Tzoufras, W. Lu, F. S. Tsung +6
A theory that describes how to load negative charge into a nonlinear, three-dimensional plasma wakefield is presented. In this regime, a laser or an electron beam blows out the pla…
