PSI_DMC
InstrumentMcStas model of the DMC powder diffractometer at PSI, CH. Please note that this instrumentfile does not include the radial collimator of DMC. To generate the full 800-bin angle coverage at DMC, you should combine two simulations using this instrumentfile, with SHIFT=0 and 0.1. This will displace the detector by half a bin-width, which is a standard procedure at the DMC diffractometer Example: mcrun PSI_DMC.instr lambda=2.5666 FileName="Na2Ca3Al2F14.laz" -n1e8
Name | Unit | Description | Default |
---|---|---|---|
lambda | AA | Choice of wavelength, affects both monochromator and source component | 2.5666 |
R | 1 | Reflectivity of non-curved guides | 0.87 |
R_curve | 1 | Reflectivity of curved guides | 0.87 |
FileName | str | Choice of reflection list filename, e.g. from McStas data dir | "Na2Ca3Al2F14.laz" |
D_PHI | deg | Focusing 'd_phi' for PowderN, see mcdoc page | 6 |
SHIFT | deg | Rotation of detector, set to 0.1 to displace by half a bin | 0 |
PACK | 1 | Powder packing factor | 0.7 |
Dw | 1 | Powder Debye-Waller factor | 0.8 |
BARNS | 1 | Flag to define if powder reflection file |F2| is in Barns or fm | 1 |
