The CS Group has developed programs to treat and model many instruments. Principal packages are shown first.

General utilities

IDA - ILL internet Data Access
LAMP - Basic data visualisation
McStas - Instrument simulation package

Ubuntu ILL-CS LiveDVD - a ready to use DVD, with preinstalled applications

Three-axis

Matlab ILL - Some Matlab programs MFit/MView (for TAS and others)
vTAS suite - Simulation of TAS spectrometers (vTAS: classical and FlatCone, vIMPS: IMPS-IN8, vUFO: IN12-UFO)
vTASSE - Simulation of a TAS spectrometer with a Spin Echo option
PkFit/Filing - Software for analysing TAS neutron data

Time of flight

TOFHR - The TOF suite (inx, plotof, tkplt, ingrid)

Small angle scattering

SANS Data Treatment (SANSsuite)

Polarised Neuton Diffraction

iFitIt - Treating polarised neutron data

BARNS

The ILL applications web portal

VME driver for Mac OS X - developed for in-house use because no such driver is provided by VME card manufacturers.
