On the gauge transformation for the rotation of the singular string in the Dirac monopole theory
Xiao-Yin Pan, Yin Chen, Yu-Qi Li +2
In the Dirac theory of the quantum-mechanical interaction of a magnetic monopole and an electric charge, the vector potential is singular from the origin to infinity along certain…
High Efficiency, Multi-Terawatt X-ray free electron lasers
Claudio Emma, Kun Fang, Juhao Wu +1
We study high efficiency, multi-terawatt peak power, few angstrom wavelength, X-ray Free Electron Lasers (X-ray FELs). To obtain these characteristics we consider an optimized undu…
Tapering studies for Terawatt level X-ray FELs with a superconducting undulator
Claudio Emma, Juhao Wu, Paul Emma +2
We study the tapering optimization scheme for a short period, less than two cm, superconducting undulator, and show that it can generate 4 keV X-ray pulses with peak power in exces…
Transverse pulse shaping and optimization of a tapered hard X-ray free electron laser
Claudio Emma, Claudio Pellegrini, Juhao Wu
Multidimensional optimization schemes for TW hard X-Ray free electron lasers are applied to the cases of transversely uniform and parabolic electron beam distributions and compared…
Generation of Coherent X-Ray Radiation Through Modulation Compression
Ji Qiang, Juhao Wu
In this paper, we propose a scheme to generate tunable coherent X-ray radiation for future light source applications. This scheme uses an energy chirped electron beam, a laser modu…
Coupled-Bunch Beam Breakup due to Resistive-Wall Wake
Jiunn-Ming Wang, Juhao Wu
The coupled-bunch beam breakup problem excited by the resistive wall wake is formulated. An approximate analytic method of finding the asymptotic behavior of the transverse bunch d…
