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

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.
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 ; contact person Dr Matthew Blakeley (neutron
Laue protein crystallography);
Los Alamos Neutron Source;
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
To all Laue experts up here
How does a Laue data is collected?
Thanks in advance to all

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.
Dear Hao Quan,
Yes I forgot about CHESS; apologies.
Charles Ballard helped with the recent installation at the Diamond
Test Beamline.
The modifications to read the Photonic Science detector Laue images on
the Diamond Test Beamline
have been made by Karen Ashton and Steve Kinder based at the
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,
