2003 NSLS Users' Meeting

High Pressure Mineral Physics Using Synchrotron Radiation

Location: Bldg. 463 - Biology Seminar Room

Date: May 21, 2003

Organizer: M. Vaughan, (SUNY, Stony Brook)

Description: Most techniques for probing materials using synchrotron radiation can be applied to materials at high pressures and temperatures using either the Diamond Anvil Cell (DAC) or the Large Volume Press (LVP, also known as the Multianvil Press). These techniques include diffraction (both energy-dispersive using white radiation and angle-dispersive using white radiation); radiographic imaging; ultrasonic interferometry; stress and strain measurements; infrared spectroscopy; Raman spectroscopy; and inelastic scattering. Presentations will be made discussing most of these techniques and scientific applications of these techniques
