McStas developments

E. Farhi, K. Lefmann and P. Willendrup, S. Jean, C, Taton, B. Rourre, V. Hugouvieux

We will present recent developments concerning the McStas Monte Carlo neutron ray-tracing simulation package, that have been carried out at the ILL, at Risoe, as well as contributed work. 1- A new Monochromator component to handle thick blade optics, bent and gradient crystals (from L. Alianelli, INFM/ILL) 2- A new fast and accurate Fermi chopper component (B. Rourre, ILL) 3- A new isotrope S(q,w) sample that handles elastic and inelastic process, coherent and incoherent, with multiple scattering in liquids, powders and amorphous samples (V. Hugouvieux, ILL) 4- Parallel computing using MPI (C. Taton, ILL) 5- VRML output of instrument geometry, as well as monitor data, to be included in HTML simulation report pages (E. Farhi, ILL) 6- A McStas web server that can follow many simulations at a time, asynchronously, with on-line data plots update (S. Jean, ILL) 7- Tripoli4 reactor simulation code (MCNP-like) event files import/export (G. Campioni, CEA) 8- New ILL guide simulation examples (E. Farhi, ILL) 9- McStas/Knoppix distribution: boot and use McStas from CD-ROM (P. Willendrup, Risoe) 10 New instrument editor/builder with highlight syntaxing (P. Willendrup, Risoe) 11 New SNS source model, updated ILL and ISIS sources (A. Garret, E. Farhi, D. Champion)
