Raman Laboratory

Located in the SNS Central Laboratory and Office Building, the Raman Laboratory combines laser spectroscopy, using 532 and 488 nm solid state lasers, with high-pressure diamond anvil cells, IR laser heating and cryogenic technologies to study molecular and lattice dynamics of materials over a wide range of pressure and temperature conditions. For example, the instruments available in the Raman lab enable researchers to expose materials to extreme temperatures of less than 10 K and as high as 3000 K and pressures as high as 1 Mbar (~ 15 million pounds per square inch). Those capabilities allow researchers to radically alter the valance electronic structure of atoms and thus change chemical processes, providing them with a fundamental insight into the molecular bonding behaviors of myriad materials. The Raman lab also functions as an ancillary facility to SNS’s high pressure diffractometer instrument SNAP.
