RELION Cathodoluminescence (CL) Microscopy System

In March 2010, we acquired a RELION cathodoluminescence (CL) microscopy system (NSF MRI Award#0922942). Fees for outside users will be $30/day, and use is limited to room availability.

CL is a useful tool for mineral identification and trace element and crystal growth zoning, and for imaging structures that are invisible under traditional light microscopy or electron microscopy.

Look at the images below that demonstrate some of our current research projects.
