Chemical and physical systems undergoing change display spectral signatures from the
radio frequency to the X-ray region of the electromagnetic spectrum. This has led to the …

Plasma-based accelerators that impart energy gain as high as several GeV to electrons or
positrons within a few centimeters have engendered a new class of diagnostic techniques …

The use of pump-probe experiments to study complex transient events has been an area of
significant interest in materials science, biology, and chemistry. While the emphasis has …

Linear-accelerator-based sources will revolutionize ultrafast x-ray science due to their
unprecedented brightness and short pulse duration. However, time-resolved studies at the …

The temporal profile of relativistic laser-plasma-accelerated electron bunches has been
characterized. Coherent transition radiation at THz frequencies, emitted at the plasma …

The electro-optic (EO) effect is a powerful diagnostic tool for determining the time profile of
ultrashort relativistic electron bunches. When a relativistic bunch passes within a few mm of …
