Relativistic Magnetic Reconnection in the Laboratory
A. Raymond, C. F. Dong, A. McKelvey +21
Magnetic reconnection is a fundamental plasma process involving an exchange of magnetic energy to plasma kinetic energy through changes in the magnetic field topology. In many astr…
A table-top laser-based source of femtosecond, collimated, ultra-relativistic positron beams
G. Sarri, W. Schumaker, A. Di Piazza +13
The generation of ultra-relativistic positron beams with short duration ( fs), small divergence ( mrad), and high density ($n_{e^+} \simeq 10^{14…
Non-invasive characterization of transverse beam emittance of electrons from a laser-plasma wakefield accelerator in the bubble regime using betatron x-ray radiation
S. Kneip, C. McGuffey, J. L. Martins +17
We propose and use a technique to measure the transverse emittance of a laser-wakefield accelerated beam of relativistic electrons. The technique is based on the simultaneous measu…
X-ray phase contrast imaging of biological specimens with tabletop synchrotron radiation
S. Kneip, C. McGuffey, F. Dollar +13
Since their discovery in 1896, x-rays have had a profound impact on science, medicine and technology. Here we show that the x-rays from a novel tabletop source of bright coherent s…
Emission and its back-reaction accompanying electron motion in relativistically strong and QED-strong pulsed laser fields
Igor V. Sokolov, John A. Nees, Victor P. Yanovsky +2
The emission from an electron in the field of a relativistically strong laser pulse is analyzed. At pulse intensities of J > 2 10^22 W/cm2 the emission from counter-propagating ele…
A Bright Spatially-Coherent Compact X-ray Synchrotron Source
S. Kneip, C. McGuffey, J. L. Martins +19
Each successive generation of x-ray machines has opened up new frontiers in science, such as the first radiographs and the determination of the structure of DNA. State-of-the-art x…
