This photo shows the spin polarised hot neutron beam facility, D3. This instrument mostly measures the Fourier components of the magnetic structures or magnetisation distributions at the atomic scale in single crystals.

This screen shot shows Igor controlling a spin polarised hot neutron beam facility (motors, encoders, power supplies, neutron counters, etc). The Mac is connected to a VME crate with two optical fibres and a BIT3 card, and to several GPIB devices.

This next screen shot shows Igor monitoring and controlling cryogenic devices as well as the variable temperature insert hosting the sample. The neutron source is regularly operational 24/24 7/7 for 50 days and Igor collects millions of points during that period.
