Jam--Nuclear Physics Data Acquisition

Jam is an easy-to-use self-contained data acquisition and analysis system for VME-based (or CAMAC-based) nuclear physics experiments. It has an easy, standard GUI for taking and sorting multi-parameter event-based data into 1-d and 2-d histograms.

    Release Notes: A new API for creating Histograms. A new tree selector replaces old choosers. A "View" menu makes it possible to display several histograms at once. The rebin feature now has a chooser-style toolbar widget. A new class lets you sort LDF files produced by the Linux version of the HRIBF DAQ platform. jam.sort.SortRoutine now includes a utility object to allow the user to easily read in text files of gain factors and offsets, and easily apply them to sorted data.

      Release Notes: A new jam.commands package handles all menu items. All menu items are also accessible from the console. Enter 'help' at the console for a list of commands. Preferences menu settings are automatically stored persistently between sessions, and are changeable via the console. When starting up in scripting mode by creating a jam.Script instance, it automatically uses quiet mode (no title screen or license dialog). Commands entered on the console saved, and the up/down arrow now retrieves the last commands entered at the console. There is a better GUI for batch export, and User Guide updates were made.

        Release Notes: New toolbar buttons, an improved layout, "Area" and "Expand" drag boxes, new HDF and event file scanning options, no more JHF files, introduction of scripting (primitive and undocumented), improved dialogs in the Histogram menu, a Windows .msi installer, and a help browser launcher. Thread timing bugs have been fixed. There is no more explicit use of the system console.

          Release Notes: Online events weren't getting written to disk, and plot repainting was slow because of anti-aliasing. On Windows, toolbar buttons had no outlines. There is a re-bin button to view 1d histograms with different bin sizes. The button layout for the action toolbar has been re-arranged. There is a 1d gate display by area highlight. The "no gate fill" preference now applies to both 1d and 2d. Javadocs have moved to a separate Jar file, JamAPI.jar. This release uses kunststoff L&F when running on Linux, sytem L&F otherwise.

            Release Notes: This version patches some memory leaks, improves the behavior and icon appearance of the histogram/gate chooser, and makes cancelling offline sorting leave the histograms, sort routine, etc. containing the results of the sort so far.
