MAPS science
17 Oct 2008




MAPS was primarily designed to tackle magnetic and structural excitations in single crystals.


With its high resolution, broad energy  range (meV to several eV) coupled to its large detector solid angle coverage ( -20 to +60 degrees in the horizontal plane and ±20 degrees in the vertical plane) MAPS is able to access the Q,Energy regime of many current condensed matter problems in fantastic detail  

The pioneering position sensitive detectors with minimal gaps in the coverage, makes it ideal for single crystal measurement but also increasing useful in addressing high resolution studies of non-dispersive excitations in powders.

For examples of the kind of exemplary science that can be performed on this instrument have a look at the recently published articles by following the e-pubs link to the right, or see the following recent highlights
