Synchrotrons produce incredibly powerful x-rays that we can use to probe our samples while they are at high pressure and high temperature. We do most of our work at the Advanced Photon Source at Argonne National lab using the D-DIA apparatus located at beam line 6BMB. We use white x-rays (as opposed to monochromatic) to produce diffraction as well as make radiographic images of our samples.
This experimental technique has given us an entirely new way of understanding what is happening inside a crystalline material as it deforms.
An example of the kinds of experiments we are doing using the D-DIA can be found on the quartz page.
