From the users perspective JBlulce provides all standard features of data acquisition software for macromolecular crystallography plus such unique capabilities as one click beamline energy change that may involve switching undulator harmonics, mirrors lanes and beam realignment, automated diffraction rtastering for finding small crystals and sweet spots on poorly diffracting crystals with automated scoring of raster cells by the number of reflections data collection along a vector automated on-the-fly fluorescent tastering, a faster and lower-irradiation compliment to the diffraction raster fully automated fluorescence measurements for MAD that include signal optimization, fast on the fly energy scanning and automated adapting of scan range to chemical shifts fly-scan minibeam realignment automated loop and crystal centering, controls for sample automounter, automated screening, data collection auditing, remote access and a lot more. The database is also accessible by the plugins. JBlulce configuration is stored in my SQL database which provides flexibility in tuning the system. All of the above makes JBlulce one of the biggest and most sophisticated EPICS client projects to date. Besides using EPICS for controlling hardware, JBlulce extensively uses EPICS databases for efficient communications between multiple instances of JBlulce clients and JBlulce plugins that can run in parallel on different computers. JBlulce also includes several EPICS State Notation servers aimed at making hardware communication more robust.

JBlulce makes full use of the industrial power and wide drivers selection of EPICS in controlling hardware all hardware communication is routed via multiple EPICS servers residing on local area network.

to compare, Blulce user interface is implemented with aging Tcl/tk language providing very restricted capabilities. Finally, the graphic interface is implemented in Java making full use of rich Java libraries and Jave IDE for debugging. further on, JBlulce makes use of unified motion controls allowing for easy scanning and optimizing of any beamline component. Another distinction is the deployment of multiple plugins that can be written in any programming language thus involving more staff into the development. Then JBlulce clients are more » designed to operate in parallel with the other beamline controls which streamlines the tasks performed by staff such as beamline preparation, maintenance, auditing and user assistance. This layers reduction provides a faster communication with hardware and an easier access to advanced hardware capabilities like on-the-fly scanning. It features only two software layers, the JBlulce clients and the EPICS servers, as compared to three layers present in Blulce and most of similar systems. Besides this interface conformity, JBlulce is a unique system in terms of architecture, spec, capability and software implementation. JBlulce (Java Beam Line Universal Integrated Configuration Environment is a data acquisition software for macromolecular crystallography conforming user interface of the SSRL Blulce that has become a de-factor standard in the field. It also includes descriptions and listings of all software written, as well as extensive user = , The document describes the computer system, and includes circuit diagrams of all custom built components. Finally, the computer program SUPERENERGY was modified to permit rapid extraction of parameters from dimensionless salt concentration maps.

Offline software was also written to permit data examination and reduction to dimensionless salt concentration maps. Extensive real time software was written to govern all phases of the data collection procedure, including probe definition, probe calibration, salt mixing test data acquisition and storage, and data editing. It performs steady state and transient monitoring and recording of up to 512 individual electrical resistance probes.

The system represents an expansion of data collection capabilities over previous equipment. A minicomputer based real time data acquisition system was designed and built to facilitate data collection during salt mixing tests in mock ups of LMFBR rod bundles.
