TL;DR: The first evidence of high harmonics from the echo-enabled harmonic generation technique in the realistic scenario where the laser energy modulation is comparable to the beam slice energy spread is reported.
Journal ArticleDOI

M. Dunning,C. Hast,Erik Hemsing,Keith Jobe,D. McCormick,J. Nelson,Tor Raubenheimer,K. Soong,Z. Szalata,D.R. Walz,Stephen Weathersby,Dao Xiang +11 more
TL;DR: Generation of density modulation at terahertz frequencies in a relativistic electron beam through laser modulation of the beam longitudinal phase space is reported and marks a significant advance toward tunable narrow band THz sources.
Journal ArticleDOI
All-optical time-resolved measurement of laser energy modulation in a relativistic electron beam
Dao Xiang,Eric R. Colby,M. Dunning,Sasha Gilevich,C. Hast,Keith Jobe,D. McCormick,J. Nelson,Tor Raubenheimer,K. Soong,Gennady Stupakov,Z. Szalata,D.R. Walz,Stephen Weathersby,M. Woodley +14 more
TL;DR: In this paper, the authors present the numerical results for the electron anomalous magnetic moment evaluated in different harmonic oscillator bases and compare to the perturbation theory result, and present an outline for future works in Sec. 4.
