| INSTRUMENTATION: | A new Huber 6+2 -circle diffractometer is permanently installed on BL7-2 for high-resolution x-ray scattering research. The spectrometer degrees of freedom are (theta,chi,phi, mu) for the sample, and (2-theta, theta-analyzer, 2-theta-analyzer, gamma) for the detector. In addition, the input wavelength can be scanned, and the spectrometer coordinates can be remotely adjusted. Software is available for scanning between an arbitrary pair of reciprocal lattice vectors. | ||||||||||||

| GENERAL DESCRIPTION: | BL7-2 is dedicated to x-ray scattering and diffraction experiments in materials and environmental science. Because of high demand, research is confined to problems that can only be addressed with this unique facility. Typical programs involve intrinsically weak scattering systems, such as two-dimensional arrays and high-resolution 3-D problems. | ||||||||||||
| 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). | ||||||||||||
