AUTOMATED SAMPLE MOUNTING SYSTEM

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。作为我们光束线持续升级的一部分，ALS机器人安装在8BM。在分析了市场上所有可用的机器人后，基于其简单性、成本、公认的性能以及位于美国同步加速器的用户社区致力于该机器人的开发，选择了ALS机器人。该机器人在液氮温度下成功通过99%的安装验收标准后于2005年11月安装。此演示是与劳伦斯伯克利国家实验室(LBNL)工程部的开发人员共同进行的。在过去的四个月里，机器人在液氮温度下进行了广泛的测试，通过不断地安装/拆卸样品销。到目前为止，它已经安装和拆卸销近2000次，错误率约为1%。杜瓦瓶可以容纳的样品，每四个冰球有16个样品。测试是通过从所有四个冰球中挑选大头针来完成的。在测试过程中，杜瓦的结冰最少。2006年3月，利用溶菌酶晶体成功地进行了实际测试。目前，机器人是由LBNL提供的软件控制的。它控制水晶的安装和拆卸。使用Click and Center协议进行晶体对中，并通过Blu-Ice软件进行数据采集。这两个项目的整合计划在不久的将来进行。这两个项目的整合计划在不久的将来进行。

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. As a part of the continuing upgrade of our beamlines, the ALS robot was installed at 8BM. After analyzing all the available robots in the market, the ALS robot was chosen based on its simplicity, cost, proven performance and a community of users, located at synchrotrons in the U.S., committed to the development of this robot. The robot was installed in November 2005 after successfully passing an acceptance criteria of 99% successful mounts at liquid nitrogen temperatures. This demonstration was conducted in conjunction with the developers at the Engineering division of Lawrence Berkeley National Laboratory (LBNL). During the last four months, the robot was tested extensively at liquid nitrogen temperature by mounting/dismounting the sample pins continuously. So far it has mounted and dismounted pins close to 2000 times with an error rate of about 1%. The dewar can accommodate 64 samples with 16 samples in four pucks. The testing was done by picking the pins from all the four pucks. There was minimum icing of the dewar during the testing. In March 2006, actual testing using lysozyme crystals was carried out successfully. At the present time the robot is controlled by LBNL supplied software. This controls crystal mounting and dismounting. The crystal centering using ¿Click and Center¿ protocol and data collection are carried out through ¿Blu-Ice¿ software. Integration of the two programs is planned for the near future. Integration of the two programs is planned for the near future.
