Focusing of an Atomic Beam
R. Bruce Doak
A bent-crystal mirror has been used to focus an atomic helium beam. The mirror is made from gold deposited onto a mica substrate to form a thin film (~5000 Å thick) of large single…
Three-dimensional view of ultrafast dynamics in photoexcited bacteriorhodopsin
Gabriela Nass Kovacs, Jacques-Philippe Colletier, Marie Grünbein +25
Bacteriorhodopsin (bR) is a light-driven proton pump. We use time-resolved crystallography at an X-ray free-electron laser to follow the structural changes in multiphoton-excited b…
A pump-probe XFEL particle injector for hydrated samples
U. Weierstall, R. B. Doak, J. C. H. Spence
We have developed a liquid jet injector system that can be used for hydrated sample delivery at X-ray Free Electron Laser (XFEL) sources and 3rd generation synchrotron sources. The…
Tomographic femtosecond X-ray diffractive imaging
K. E. Schmidt, J. C. H. Spence, U. Weierstall +6
A method is proposed for obtaining three simultaneous projections of a target from a single radiation pulse, which also allows the relative orientation of successive targets to be…
Gas Dynamic Virtual Nozzle for Generation of Microscopic Droplet Streams
D. P. DePonte, U. Weierstall, D. Starodub +3
As shown by Ganan-Calvo and co-workers, a free liquid jet can be compressed in iameter through gas-dynamic forces exerted by a co-flowing gas, obviating the need for a solid nozzle…
X-Ray Powder Diffraction from Sub-Micron Crystals of Photosystem-1 Membrane Protein
D. A. Shapiro, D. DePonte, R. B. Doak +9
We demonstrate that powder diffraction data can be collected from sub-micron crystals of a mbrane protein with nearly two orders of magnitude more atoms than the molecules commonly…
