SOFTWARE DEVELOPMENT FOR SMALL ANGLE X-RAY SCATTERING DATA COLLECTION, BASED ON

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。我们升级了分布式控制系统(DCS)和相应的图形用户界面BLU-Ice，这些系统去年首次用于小角度散射实验。我们为光束线控制和数据采集增加了新的和改进的功能，包括：1)狭缝优化的自动化，2)样品位置搜索的自动化，3)相机长度改变的自动化，4)样品定位的自动化，5)不同位置参数下的多样品测量。还对部分分布式控制系统进行了修改，以便将数据采集参数写入图像数据的标题部分，以供以后在数据分析中使用。所有这些新的功能和特性使工作人员的束线优化和用户的数据采集更加直观、高效和用户友好，使工作人员可以根据特定的用户需求快速配置和优化束线。现在可以自动运行多达10个编程的测量系列，为用户节省了并行数据分析的宝贵时间。改进的用户友好性使用户，特别是那些一年只在设施中呆几次的用户，可以专注于运行实验，而不是学习实验控制软件。

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. We have upgraded the distributed control system (DCS) and corresponding graphical user interface, Blu-Ice, which were first used for small angle scattering experiments last year. We added new and improved capabilities for beam line control and data acquisition, including: 1) automation of slit optimization, 2) automation of sample position search, 3) automation of camera length change, 4) automation of sample positioning, 5) multiple sample measurements at different positional parameters. There are also modifications made to part of the DCS so that data acquisition parameters are written in the header portion of image data for later use in data analyses. All the new capabilities and features make the beam line optimization for the staff members and data acquisition for the users more intuitive, efficient, and user friendly so that the staff members can configure and optimize the beam line for specific user requirements quickly. It is now possible to run up to 10 programmed series of measurements automatically, saving users precious time for parallel data analysis. The improved user friendliness allows users, especially those who are at the facility only a few times a year, to concentrate on running the experiments instead of learning the experiment control software.
