TRANSCRIPT
GSECARS Update13-BM-C Side Station
•Scientific programs is DAC diffraction and surface science
•Proposed partial funding as COMPRES Infrastructure Project. COMPRES could not fund, recommended submission to NSF-MRI
•Funded by MRI for $550K ($100K less than requested).
•Monochromator prototype being constructed•Will order vertical mirror soon•Large Newport diffractometer will be
delivered in July, DOE funded.
GSECARS Update
13-ID-D Laser Heated Diamond Anvil System
• Complete rebuild of system
• Monolithic table for increased stability
• Laser upgrade with newb crystals to 80W per laser
• New MAR-345 online image plate reader ordered
GSECARS LVP Technical Developments
• D-DIA with monochromatic diffraction
• High-pressure tomography apparatus
• High-pressure angle-dispersive powder diffraction using an energy-dispersive setup and a white source
