The Test_Magnon_bcc_TAS Instrument

Generic TAS instrument for test of samples with dispersions.

Identification

Description

Generic TAS instrument for test of samples with dispersions. Modeled over the RITA-2 instrument at PSI (one analyzer only). The instrument is able to position in q-space at q=(h 0 0) and fixed Ei and Ef. This can be used to longitudinal constant-E scans or constant-q scans. In addition, transverse constant-E scans can be made by scanning the sample orientation A3.

Input parameters

Parameters in boldface are required; the others are optional.
NameUnitDescriptionDefault
hwmeVNeutron energy transfer0.5
EfmeVFinal neutron energy5
A3offsetdegsample rotation around a vertical axis0
A3auto1Flag for selecting automatic setting of A3 to have q-vector along [h 0 0] (0=manual; 1=auto)1
