For the daring, the McStas development code is available for installation through our SVN repository. Please consult this page for further instructions.

December 8th, 2009: McStas 1.12a on Ubuntu 9.10

People running Ubuntu versions prior to 9.10 and McStas installed from the mcstas-1.12a.deb debian package are adviced NOT TO UPGRADE Ubuntu, as PGPLOT/Fortran related package dependencies can not easily be resolved.

If you upgrade anyway or install from scratch on Ubuntu 9.10, the easiest way of getting McStas 1.12a working is:

  1. Install certain Ubuntu packages by
  2. Run sudo dpkg-reconfigure dash, say "no" to installing dash as /bin/sh
  3. Get the mcstas-1.12a-src.tar.gz package via this link
  4. Unpack, build and install by

Alternatively, wait 1-2 months and McStas 2.0 should be ready.

September 24th, 2009: McStas 1.12a on Mac OS X 10.6 Snow Leopard

Unfortunately, a couple of work-arounds are needed to install McStas on the new version of Mac OS. When following the instructions in README.TXT on the dmg image:

August 29th, 2009: PSI official McStas partner

We are happy to announce that PSI is now an official McStas partner site, and that Uwe Filges has joined the developer team. The McStas team has been working closely together with Uwe for several years, e.g. in the MCNSI network.

August 21st, 2009: Code repository changes.

As we want to share code with our "sister project" in X-ray scattering, McXtrace, a new common infrastructure is beeing built up. In the future, the McStas and McXtrace code repository, bug tracking etc. will be hosted under the McCode domain. Consequently, some links and website features can be expected broken - and fixed - in the near future.

May 18th, 2009: McStas related slides / posters from ICNS

We have gathered talk and poster material from ICNS 2009 in a special conference page. Work by the McStas team and close connections have been added.

We would also like thank those of the ICNS attendees that were in our workshop or came by our posters for interesting discussions.

April 8th, 2009: Minor bug in McStas 1.12a (not to be updated)

It seems that one of the example instruments (prisma2.instr) can not be compiled with McStas 1.12 and the newest version of gcc, 4.3.2. Using the older, stable gcc 3.4 works just fine.

April 2nd/3rd, 2009: McStas 1.12a released

The long awaited update release, McStas 1.12a is finally available, grab it from the download page.

The changes since last stable release (1.12) are available here.

McStas 1.12a is essentially a bugfix release, and the last release in the 1.x series. McStas 2.0 will be released late 2009 / early 2010 and will introduce new features that will likely break ceartain backward compatibility, hence we move from the 1.x series.
