McStas 2.0 is finally ready and has been uploaded to our download page!
The full and long list of changes since last official release is available here.
McStas 2.0 is available for the following platforms
Hope you will enjoy this little X-mas present! :-)
Please contact us if you experience trouble with McStas 2.0 (we might not answer this side of New Year's ;-) )
Seasons greetings from all of the McStas team,
A bug in the internal path definitions of the RC1 packages prevented the tools from working properly on Unix systems. For this reason, I have pushed the update 2.0RC2 to http://mcstas-20rc2.mcstas.org
Sorry for any inconvenience
A public beta release of McStas 2.0 called 2.0RC1 has finally been released!
McStas 2.0RC1 is a public beta leading up to the long awaited official McStas 2.0. It is a beta release, but we expect that differences to 2.0 will be minimal.
The full and long list of changes since last official release is available here: http://mcstas-20rc1.mcstas.org/CHANGES_McStas
* If you do not find yourself credited in the long list of contributions - please remind me *
* There is still time if you have contributions you would like us to include in the official 2.0 *
McStas 2.0RC1 is available through this link: http://mcstas-20rc1.mcstas.org for the following platforms
!! Please read the README file provided with each platform type before installing !!
For Unix systems we provide a migration script that will allow you to let an existing 1.x release (i.e. 1.12c) co-exist with the new release.
On behalf of the McStas team, Peter Willendrup
A new DMG for Mac OS X 10.8 Mountain Lion has been put together and can be found in the download section.
As Apple have discontinued distribution of X11, you need to install XQuartz before installing McStas.
You also need to install Command Line Tools inside Xcode (Xcode -> Preferences-> Downloads -> Components) and also allow installation of third party software (System Preferences -> Security & Privacy -> General -> Allow applications downloaded from: Anywhere) - can be reset after installation of SciPDL etc. from the DMG.
Note that to enable multi-core / parallel simulations, you need to compile openmpi yourself before installing McStas, since it is not provided by Apple on Lion and Mountain Lion. Alternatively you can perhaps get it via MacPorts.
The DMG should also work on Lion - but all software on the DMG must be reinstalled if McStas was previously installed.
Linda Udby has contributed her detailed description of the RITA-II instrument for use with McStas 1.12c. RITA-II is a so-called re-invented triple axis with a multiplexed analyzer system. The contribution can be downloaded from our share section (instrument info).
As part of her PhD thesis, Linda used this very detailed model of RITA-II to perform virtual experiments, thereby deriving analysis parameters for her studies of Superoxygenated LSCO.
The hkl routine embedded in the instrument code is similar to what is found in templateTAS by Emmanuel Farhi. Further, the instrument features a multitude of input parameters to control all aspects of the virtual experiment. The instrument contains both an incoherent scatterer, a powder sample, a single crystal and a phonon-simple that can be selected using input parameters.
The McStas team are really greatful for this nice contribution that will also be be part of McStas 2.0.
The interim ESS DMSC (Data Management and Software Center for the European Spallation Source) located at the Niels Bohr Institute, University of Copenhagen is seeking a candidate for scientific software development within areas of data analysis and simulation. More specifically, the work is oriented toward integration of the McStas and Mantid software packages.
The advert is available through this link.

As reported to email@example.com, the McStas 1.12c dmg for OS X Lion was unfortunately corrupt. A new version of the image has been uploaded. The filename is slightly different to be able to distinguish the image from older downloads you may have.
A couple of annoyances have been reported, here they are plus relevant workarounds:
A reorganisation at DTU and RISØ DTU has resulted in a new home for the DTU effort on McStas, namely DTU Physics.
Hence, Erik Knudsen and Peter Willendrup have a new affiliation, see the Contact page.
At our new home we will be part of a dedicated neutron- and X-ray scattering group, which we think will become a very good home!
