TLDR
A bunch-length measuring method has been developed to measure the subpicosecond electron pulses generated at the Stanford University Short Intense Electron Source (SUNSHINE) facility, which demonstrates subpicOSEcond resolving power that cannot be achieved by existing time-resolved methods.Abstract:
A bunch-length measuring method has been developed to measure the subpicosecond electron pulses generated at the Stanford University Short Intense Electron Source (SUNSHINE) facility. This method utilizes a far-infrared Michelson interferometer to measure coherent transition radiation emitted at wavelengths longer than or equal to the bunch length via optical autocorrelation. To analyze the measurement, a simple and systematic way has also been developed, which considers interference effects on the interferogram caused by the beam splitter; hence the electron bunch length can be easily obtained from the measurement. This simple, low-cost, frequency-resolved autocorrelation method demonstrates subpicosecond resolving power that cannot be achieved by existing time-resolved methods.read more

Bunch length measurement of picosecond electron beams from a photoinjector using coherent transition radiation
TL;DR: In this paper, the bunch length of an electron beam derived from the UCLA Saturnus photoinjector has been measured using a 45° CTR foil and a polarizing Michelson interferometer allowed measurement of the auto-correlation of the coherent transition radiation signal.

The relationship between dynamics and structure in the far infrared absorption spectrum of liquid water
Kristina Woods,H. Wiedemann +1 more
TL;DR: In this paper, the absorption spectrum of liquid water is measured at a temperature ranging from 269 to 323 K. In the infrared spectrum, modes that are related to the local structure are observed.
