Reflectometer D17

D17 is the first ILL dedicated reflectometer and it has been designed to be as flexible as possible in resolution and modes of operation. The instrument is suitable for the analysis of surface structures in solids and solid/liquid interfaces. Horizontal surface experiments, such as free liquids, will suffer from a severe restriction in Q-range and flux and are thus not recommended for this instrument.

COSMOS

COSMOS is a program that will take raw TOF data for multiple angles, it will calibrate to the incident wavelength distribution and the detector efficiency, and will output reflectivity vs. Q. 

Start the program by typing COSMOS in the LAMP manipulations window.

Note that, due to width specifications, a column is usually hidden to the right of the window.  Use the slider bar at the bottom of the COSMOS window to find it.
