Description

This instrument is a simple model of the thermal H8 triple-axis
spectrometer from former Brookhaven reactor. It has an (polarizing)
monochromator and a (polarizaing) analyzer. The sample is a vanadium
cylinder.
Three cases can be done:
-1) Spin flip (flipper is inserted): Up->Down
0) No polarization: Up/Down->Up/Down
1) No spin flip: Up->Up
The Vanadium sample should give I(0)=2*(I(-1)+I(1)) and I(-1)=2*I(1).

Input parameters

Parameters in boldface are required; the others are optional.
