# The `Test_Pol_TripleAxis` Instrument

Based on Emmanuel Farhi's thermal H8 triple-axis spectrometer from Brookhaven reactor

## 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).

    Example: mcrun Test_Pol_TripleAxis.instr OPTION=1
