| GENERAL DESCRIPTION: |
BL4-3 is dedicated to x-ray absorption spectroscopy measurements with special capabilities for soft-energy (2.4-6 keV) studies in addition to hard x-rays. Equipment includes multi-array Ge detectors, LHe cryostat and soft x-ray instrumentation. Applicationas include mainly MEIS, biology and materials science, with some use in chemistry andphysics. This station enables soft x-ray measurement (from S K-edge and up). | ||||||||||||
| Sample Preparation Labs: | The SSRL Structural Molecular Biology (SMB) Sample Preparation Laboratories are available to users by prearrangement. To use a laboratory, users must complete laboratory training, and provide a list of all chemicals to be brought, used or stored in the Sample Preparation Laboratory. For details, contact Cynthia Patty (650-926-3925). | ||||||||||||
