High Pressure/Laser/Raman

a key facility to further high-pressure neutron research at ORNL; it is a one of a kind laboratory that enables, diamond anvil cell preparation, in situ high pressure measurements with Raman spectroscopy and in situ laser heating; these resources are used in collaboration with neutron users for complementary measurements to go along in situ neutron pressure measurements; the laboratory will also be used to educate students; for example, prior to COVID-19, a project had been approved that would have seen a GEM fellow spend their summer internship predominantly conducting experiments in this laboratory. Equipment housed in this lab: Multiple Lasers of All Power Levels (ranging from Blue to IR Radiation), Several High-Power Microscopes and Diamond Anvil Cells, EDM Driller, Laser-Driller, Diamond Saw
