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…
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…
Single Particle Detection System for Strong-Field QED Experiments
F. C. Salgado, N. Cavanagh, M. Tamburini +23
Measuring signatures of strong-field quantum electrodynamics (SF-QED) processes in an intense laser field is an experimental challenge: it requires detectors to be highly sensitive…
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…
GPU Accelerated Simulation of Channeling Radiation of Relativistic Particles
Christian Flohr Nielsen
In this paper we describe and demonstrate a C++ code written to determine the trajectory of particles traversing oriented single crystals and a CUDA code written to evaluate the ra…
Quantum radiation reaction in aligned crystals beyond the local constant field approximation
T. N. Wistisen, A. Di Piazza, C. F. Nielsen +2
We report on experimental spectra of photons radiated by 50 GeV positrons crossing silicon single crystals of thicknesses 1.1 mm, 2.0 mm, 4.2 mm, and 6.2 mm at sufficiently small a…
