The SE_example2 Instrument

Mockup of transmission Spin-Echo, written for PNCMI 2010 school in Delft. This version uses Pol_FieldBox for description of the fields.

Identification

Description

This instrument shows the use of essential McStas polarisation components, including Pol_mirror, Pol_FieldBox and MeanPolLambda_monitor.

Pol_mirror is used to polarize and analyze the incoming and scattered beams.
Pol_simpleBfield is used to define guidefields and flippers.
MeanPolLambda_montior is used to monitor beam polarisation.

Example: mcrun SE_example2.instr dBz=-0.0001,0.0001 -N41 -n1e5 

Input parameters

Parameters in boldface are required; the others are optional.
