SMB BEAM LINE UPGRADES

本子项目是利用由NIH/NCRR资助的中心赠款提供的资源的众多研究子项目之一。子项目和研究者（PI）可能已经从另一个NIH来源获得了主要资金，因此可以在其他CRISP条目中表示。列出的机构是中心的，不一定是研究者的机构。该项目旨在升级SSRL的SMB波束线，使用户能够利用SPEAR3加速器升级，将电流增加到500 mA，降低发射度，同时保持较长的波束寿命。所有部件都准备好安装在7号梁线上。在2005年8月初运行结束时，对整个旧梁线进行了快速拆卸，并开始安装新设备。在2006财年开始之前，所有凹室设备都已安装完毕，重点转移到建造舱室和准备基础设施上。预计BL7安装的这一阶段将需要1月份，随后不久将投入使用用于晶体学的新光束线7-1和用于x射线吸收光谱的新光束线7-3。

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, lower the emittance while maintaining the long beam life times. All parts were readied for installation on beam line 7. At the end of the run in early August 2005, a rapid disassembly of the entire old beam line took place and the installation of the new equipment commenced. All in-alcove equipment was installed before the start of the FY2006 run, and the focus shifted to building of hutches and readying infrastructure. It is expected that this phase of the BL7 installation will require the month of January followed shortly thereafter by the commissioning of the new beam lines 7-1 for crystallography and 7-3 for x-ray absorption spectroscopy.
