For the MX endstation we’ve characterized the dependence of the direct beam on detector distance and 2-theta. We collected 4 sweeps of the detector from 120mm to 1600mm combined with 2-theta offsets from 0º up to 12º. These are the gnuplot 3D plots of the data. This set of 3D plots uses gnuplots pm3d settings…

FoXS, a new webapp which uses the Debye formula for calculating theoretical scattering profiles, has been made available on the ModBase website. Give it a try to see how it compares to CRYSOL. FoXS is a method for computing a theoretical scattering profile of a structure and fitting of experimental profile. FoXS can be used…

For older browsers, or non-flash enabled mobile browsers, we offer the old skool status page which has convenient small png files showing the last 24 hours of beamline data, but if you want to have a hands-on experience you might want to try out our new Google-style annotated time lines. If you’re familiar with the Google finance…

The SIBYLS beamline has recently been awarded 50,000 hours on the NERSC (National Energy Research Scientific Computing Center) to perform solution structure modeling using experimental SAXS data. Besides the usual ab-initio reconstructions programs a new approach in rigid body modeling BILBOMD has been parallelized on the NERSC supercomputer. It is commonly acknowledged that flexibility between domains of…

Due to DOE budget cuts and planned upgrades to the ALS storage ring we will have no light until October 11th. Hopefully we will be scheduling beamtime for Oct/Nov/Dec within the next couple of weeks. If you are interested in obtaining General Users shifts please fill out an online application.

As of Monday April 7th – The Director of the National Institutes of Health shall require that all investigators funded by the NIH submit or have submitted for them to the National Library of Medicine’s PubMed Central an electronic version of their final, peer-reviewed manuscripts upon acceptance for publication, to be made publicly available no…

The Protein Data Bank is requiring, effective February 1, 2008 (i.e. tomorrow), that structure factor amplitudes/intensities for crystal structures [must be deposited](http://www.rcsb.org/pdb/static.do?p=general_information/news_publications/news/news_2007.html#20071204) along with model coordinates. So if you need some structure factors to go along with your PDBs we can help you out. Apply for beamtime via the red “[GENERAL USER PROPOSAL](http://www-als.lbl.gov/als/quickguide/independinvest.html)” link in…
