fermi chopper component

[Stuart Rycroft]

Hello

I am trying to simulate a Fermi chopper with a straight channel.  The
component in mcstas (written by Andrew Garrett) simulates a curved Fermi
chopper.  I am having difficulty following the code in order to change to
a straight channeled chopper.

Can anyone help?
