SEES - ALS/Beamline 12.2.2 Partnership
Embedded Files
SEES continues to enable high pressure mineral physics users (previously, the COMPRES user community) to produce the best possible science at the Advanced Light Source (ALS) through provision of user facilities optimized for their needs, a comprehensive research infrastructure, high-quality personalized user support, and dedicated beam time. SEES maintains support beamline 12.2.2 for two beamline scientists, with additional support for expendable supplies, and upgrades of some equipment.
