SMB BEAM LINE UPGRADES

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 该项目旨在升级SSRL的SMB束线，使用户能够受益于SPEAR 3加速器升级，这将在较低的发射度下将电流增加到500 mA，同时保持较长的束寿命。 7号光束线已投入使用，光束进入BL 7 -1站（大分子晶体学）和BL 7 -3站（X射线吸收光谱学），测量了第一批数据集。 Beam生产线9的升级已经完成，所有三个工作站（大分子晶体学和X射线吸收光谱学）的一般用户计划已经恢复。 BL 4 -2升级（小角度X射线散射）进行了子系统的高级规划和组装。

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. Beam Line 7 was commissioned and beam brought into stations BL7-1 (macromolecular crystallography) and BL7-3 (x-ray absorption spectroscopy), with first data sets measured. The Beam Line 9 upgrade was completed and the general user schedule resumed on all three stations (macromolecular crystallography and x-ray absorption sepctroscopy). Advanced planning and assembly of subsystems took place for the BL4-2 upgrade (small angle x-ray scattering).
