Based on roughly 1500 complete Laue data sets containing more than 45000 Laue patterns, I can say the following: How to collect Laue data? 1.) put crystal on (capillary or cryo is fine) 2.) switch on X-rays (or Neutrons) for time-resolved studies select one or more pulses else forget

Dear John, of course you are right, apologies for my little exaggeration. Warmest regards Marius Dear Marius, To these two centres to which you refer we can add:- Diamond Light Source; contact person Prof David Allan (small molecule Laue X-ray crystallography); Institut Laue Langevin ;

Hi, A Laue diffraction pattern is a diffraction pattern recorded using polychromatic (white) radiation. Hence the beam line optics is for focusing the radiation onto the sample (the crystal) but not to select a single wavelength (a monochromator). Just to make it simple to understand.

there is a small but brave community that actually attempted to collect Laue data on proteins with modern synchrotron sources. They are all centered around Keith Moffat in Chicago and Michael Wulff in Grenoble. Maybe you contact these people: D. Bourgeois at the ESRF, V. Srajer or Z. Ren at the

Dear Rex, I can speak for the 'Daresbury Laue Software Suite', which is available with full documentation and tutorials from :- http://www.srs.ac.uk/px/jwc_laue/laue_top.html A wide range of validation tests involving both biological and chemical crystallography have been made of the software and

Dear Rex, the most popular one seems the Daresbury Laboratory Laue Software Suite, available via http://www.srs.ac.uk/px/jwc_laue/laue_top.html I have not, though, managed to compile the whole suite. There is also a commercial product from renzresearch.com, as M. Blakeley has pointed out to me.

A version of the Daresbury Laue programs that can process ADSC CCD data (Q-210, Q-315, etc.), and also has some improvements to the indexing routine for the case of sparse diffraction patterns, is available from CHESS, ftp://waterline.chess.cornell.edu/pub Some documentation (as text files)
