Transition to AreaDetector  The APS is transitioning from ImageServer (and other software) to AreaDetector for support of all 2-D detectors  Many drivers have been done  We (and others) are working on developing more drivers  Still need software –Need better support for viewing live data –Need better support for viewing file data –Integrate image view with things like ROI plugin –Looking for ways to streamline the acquisition/analysis process Scripting Flow control Integrating GDA and AreaDetector, John Hammonds, EPICS Collaboration Meeting, October 11-15,

Live Data View  Monitor for a new Image (i.e., watch UniqueID of NDStdArray plug-in)  When a new image arrives, grab type & size of the image and a copy of the image  Send a copy of the image to a display  ImageJ(demo), IDL Integrating GDA and AreaDetector, John Hammonds, EPICS Collaboration Meeting, October 11-15,

Area Detector Classes Integrating GDA and AreaDetector, John Hammonds, EPICS Collaboration Meeting, October 11-15, Map the structure of AreaDetector to Java so that you can access component PVs in GDA Implement GDAs Findable (getName() & setName(String Name)) and Configurable (configure()) Configure calls routine setupChannelTypes(); override this in each class to extend a map of channel name & type

NDImage Integrating GDA and AreaDetector, John Hammonds, EPICS Collaboration Meeting, October 11-15, Add channels to monitor (in addition to those in plug-in base) Trigger to watch Image Ties to GDA Plot image Get/set which viewer plot will go to Get image as a GDA dataset

Conclusions  This is a work in progress  We still have a lot to learn and decide  We are still trying to decide how much we want happening in server and how much should be in the client  Over the next few months we are planning to deploy a GDA/CSS prototype for the Pinhole SAXS instrument at 15-ID at the APS. We will be starting with the AreaDetector and some CSS/BOY OPIs. Add scans later with Jython scripts & GUI setup  More detail Friday (GDA Workshop)  Thanks to –Mark Rivers for AreaDetector –Diamond for GDA Esp. Paul Gibbons, Matthew Webber, Richard Woolliscroft –Ken Evans and Brian Tieman for allowing me to use them as sounding board Integrating GDA and AreaDetector, John Hammonds, EPICS Collaboration Meeting, October 11-15,
