Description

This instrument demonstrates how to use the component
Pol_Bfield with a constant field to make a Mezei Spin flipper.

This instrument matches the example: Test_Pol_MSF (under tests)
made with the old component: Pol_constBfield

Examples

(Test cases in bold)

• Test: ROT_ANGLE=180 Detector: pollambdaMonitor2z_I=0.0768972
• Test: ROT_ANGLE=180 ONOFF=1 Detector: pollambdaMonitor2z_I=0.0768972
• Test: ROT_ANGLE=180 ONOFF=2 Detector: pollambdaMonitor2z_I=0.0768972
• Test: ROT_ANGLE=180 ONOFF=3 Detector: pollambdaMonitor2z_I=0.0768972

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
ROT_ANGLE	deg	Angle that the spin of a 5AA neutron rotates in the 0.2 m magnet	180
ONOFF		Should we use a window description (with a _stop comp) to turn the field on and off.	0
