Energy recovery in filament-regime plasma wakefield acceleration of positron beams
Max Varverakis, Robert Holtzapple, Severin Diederichs +2
Plasma wakefield acceleration using an electron filament offers stable, high-gradient, high-quality acceleration of positron beams analogous to the acceleration of electrons in the…
Differential Measurement of Trident Production in Strong Electromagnetic Fields
Christian F. Nielsen, Robert Holtzapple, Mads M. Lund +4
In this paper, we present experimental results and numerical simulations of trident production, , in a strong electromagnetic field. The experiment was co…
A Liquid Xenon Positron Target Concept
Max Varverakis, Robert Holtzapple, Hiroki Fujii +1
Positron targets are a critical component of future Linear Colliders. Traditional targets are composed of high-Z metals that become brittle over time due to constant bombardment by…
Precision Measurement of Trident Production in Strong Electromagnetic Fields
Christian F. Nielsen, Robert Holtzapple, Mads M. Lund +3
We demonstrate experimentally that the trident process in a strong external field, with a spatial extension comparable to the effective radiation length,…
High-resolution modeling of nonlinear Compton scattering in focused laser pulses
Christian F. Nielsen, Robert Holtzapple, Ben King
A semi-classical approach is used to calculate radiation emission in the collision of an electron with an intense focused laser pulse. The results are compared to predictions from…
Radiation Reaction near the Classical Limit in Aligned Crystals
Christian F. Nielsen, Jens B. Justesen, Allan H. Sørensen +2
An accelerated charged particle emits electromagnetic radiation. If the driving force is sufficiently strong, the radiated energy becomes comparable to the kinetic energy of the pa…
