SMB BEAM LINE UPGRADES

点击翻译按钮获取中文摘要

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. This project is for upgrading the SMB beam lines at SSRL to enable users to take benefit of the SPEAR3 accelerator upgrade, which will increase the current to 500 mA, at lower emittance while maintaining the long beam life times. BL7-1 (macromolecular crystallography) was opened to full general user program. The BL4 wiggler was moved to its new location, the infrastructure and hutch were installed for BL4-2 (SAXS), in-alcove optics installed, the LN-cooled monochromator assembled and is undergoing final controls testing before installation. Current expectation is light in the BL4-2 hutch in March 2008.
