The new VITESS versions 3.5 and 4.0 have recently been finished. VITESS 4 is designed to be used for virtual experiments, e.g. at MLZ. The instruments are stored as yaml files, which enables changing the instrument parameters from NICOS (as in a real experiment). For maintenance and performance reasons, the new GUI is written in Qt and the monitor output will be visualized using the FZJ program GR. Version 4.0 will not have the complete set of modules, but only those found in many instruments, altogether 36 out of 58. Additionally, the use of parameters from files is reduced. It is under test now for virtual experiments at the neutron reflectometer MARIA at MLZ in Garching. As it will take time to get VITESS 4 complete and faultless, version 3 will still be needed for some time. VITESS 3.5 contains several new features that are needed for instrument simulations for the HBS, e.g. a source module for HBS and a rotating monochromator. It also contains already many improvements realized for the virtual experiments like additional features for the reflectometer sample and monitor update during the run. The HBS source is also available in McStas. Next year, version 3.6 will be written with the main new feature to save instruments, stored under version 3, in the new format using yaml files. Then, all missing modules will be added to version 4 and released as version 4.1. We will present the main new features of version 3.5 and 4.0 and also show how to simulate the HBS source, both in VITESS and in McStas. |
