What is the Difference Between Each Mode Reflectometry Can Run in?

[JackEAllen]

I'm struggling to find out what the different modes of operation are for reflectometry instruments such as NR mode and Polarised mode.
Can anyone explain them to me or point me in the right direction to find out?

You can find information of the component setups for each mode HERE. There is also I basic 2D diagram of the setup for reflectometers which should help act as a reference point for context.

Table of our understanding for each mode what is in the beam and what is tracking the beam. States are:

• O: Out of the beam
• I: In the beam but not tracking it
• T: In the beam and tracking it

Mode	S1	Polariser	S2	sample stack	ideal sample point	S3	analyser	S4	Detector
NR (Neutron reflecting)	T	O	T	I	T	T	O	T	T
polarised	T	T	T	I	T	T	O	T	T

In sim language

Mode | S1 Height above beam | Polariser angle and height above
