Simulation project powder: A powder diffractometer

From E-neutrons wiki
Jump to navigation Jump to search

DMC is a cold-neutron powder diffractometer situated at PSI. This instrument is optimized for high intensity, it has a medium \(q\)-resolution and a small-to-medium \(q\)-range. This makes DMC well suited for the study of magnetic structures. Here, we will, however, discuss only nuclear structures.

This assignment takes you through the construction of a full DMC simulation. Then, you will perform a virtual powder diffraction experiment. At last, you will use the state-of-the-art analysis package FULLPROF to analyze the data and determine the crystal structure of an unknown substance.

If time allows, you are encouraged to suggest and investigate improvements to the spectrometer.
