“…With the development of accelerator technology, various techniques have been developed to produce short-pulse electron bunches. Consequently, active research and development of terahertz light sources using accelerators have been conducted [3][4][5][6][7][8][9][10][11]. In particular, at Nihon University, various types of terahertz light sources have been developed over the past decade.…”

This study presents a novel technology to measure electron bunch length with a high time resolution by measuring coherent synchrotron radiation using a narrow-band detector at Laboratory for Electron Beam Research and Application (LEBRA)—an S-band linear accelerator facility for free-electron lasers. The form factor was observed to decrease exponentially with charge—in concordance with the relationship between the intensity of the coherent synchrotron radiation and the magnitude of electron bunch charge—in the region in which the effect of electron bunch charge on bunch length is negligible. The calculated root-mean-square bunch length was observed to agree well with the value determined from the spectral shape obtained. The aforementioned results are expected to be useful in real-time observation of small changes in electron bunches in advanced accelerators.

“…The microfluidics-based devices that are being developed for large-scale automated combinatorial studies of crystallization conditions use smaller and smaller volumes of protein, limiting the size of crystals that may be grown in them (Shim et al, 2007). A few X-ray beamlines exist, and more are being developed, with sufficiently powerful <10 mm diameter beams to produce observable diffraction from <10 mm crystals (Moukhametzianov et al, 2008;Sanishvili et al, 2008;Bilderback et al, 2006;Dierker, 2008). Hence, it appears that the single-shot-per-crystal regime is of more than theoretical interest.…”

Crystal size is an important factor in determining the number of diffraction patterns which may be obtained from a protein crystal before severe radiation damage sets in. As crystal dimensions decrease this number is reduced, eventually falling to one, at which point a complete data set must be assembled using data from multiple crystals. When only a single exposure is to be collected from each crystal, the polychromatic Laue technique may be preferable to monochromatic methods owing to its simultaneous recording of a large number of fully recorded reflections per image. To assess the feasibility of solving structures using single Laue images from multiple crystals, data were collected using a 'pink' beam at the CHESS D1 station from groups of lysozyme crystals with dimensions of the order of 20-30 microm mounted on MicroMesh grids. Single-shot Laue data were used for structure determination by molecular replacement and correct solutions were obtained even when as few as five crystals were used.

We show that a free-electron laser oscillator generating x rays with wavelengths of about 1 A is feasible using ultralow emittance electron beams of a multi-GeV energy-recovery linac, combined with a low-loss crystal cavity. The device will produce x-ray pulses with 10{9} photons at a repetition rate of 1-100 MHz. The pulses are temporarily and transversely coherent, with a rms bandwidth of about 2 meV, and rms pulse length of about 1 ps.
