Simulated
scattering from a hollow-cylinder vanadium
sample.
|
| The plot shows the intensity of scattered neutrons (red is
highest intensity). The sample is at the center of the sphere with the
neutron beam coming from the left. Clearly seen is the shadowing effect
of the sample causing a lower intensity opposite the beam. Also seen is
the effect of the non-symmetric geometry of the sample, causing lower intensity
directly above and to the side of the sample. |
A website has been set up for the forthcoming workshop on instrumentation for the ESS. The workshop is a continuation of the work started at the Rencurel ESS workshop and will take place at the island of Ven.
McStas user Tom Chen has recently made the McStas team aware of a bug preventing him to do optimization from mcgui on Windows, which always selected --ncount=1e6. Further testing showed that both scans and --optim runs using both mcgui and mcrun were affected.
Only Windows installations of McStas 1.12 are affected.
To remedy the problem, please replace your c:\McStas\bin\mcrun.pl with this version.
An updated version of McStas 1.12 with this and other fixes will be made available within a few weeks.
The Rencurel ESS workshop was a great succes, and a similar workshop has now been arranged for 2008.
This years workshop will take place at the island of Ven in the Øresund strait between Sweden and Denmark, October 27th-31st. No official workshop webpage is available yet, a link will be posted here when this changes.
The workshop is arranged and sponsored by the ESS Lund secretariat and the Niels Bohr Institute in Copenhagen.
Risø DTU is in charge of the computing infrastructure and has partnered with IBM Denmark who have kindly made computer hardware available to the workshop.

During a meeting this summer, the developer team agreed that time has come to release a new major release of McStas, leaving the 1.x series. As explained in the manual, a change in the major release number should only occur in case of loss of backward compatibility. The main areas where this will happen is:
Since we have now defined that the next version will break (some) backward compatibilty, this list might extend slightly.
McStas 1.12 will remain supported for one year after release of McStas 2.0, allowing users a calm transition period.
Possibly a bugfix release of McStas 1.12 will appear during fall/winter of 2008.
McStas 2.0 is planned for spring 2009
