The Generic Data Acquisition (GDA)* framework is an open source, Java and Eclipse RCP based data acquisition software for synchrotron and neutron facilities. A new implementation of the GDA on the B18 beamline at the Diamond synchrotron will be discussed. This beamline performs XAS energy scanning experiments and includes a continuous-scan mode of the monochromator synchronised with various detectors for Quick EXAFS (QEXAFS) experiments. A new perspective for the GDA's Eclipse RCP GUI has been developed in which graphical editors are used to write xml files which hold experimental parameters. The same xml files are marshalled by the GDA server to create Java beans used by the Jython scripts run within the GDA server. The underlying motion control is provided by EPICS. The new Eclipse RCP GUI and the integration and synchronisation between the two software systems and the detectors shall be covered.

WEPMN013 Recent Developments in Synchronised Motion Control at Diamond Light Source 901

  At Diamond Light Source the EPICS control system is used with a variety of motion controllers. The use of EPICS ensures a common interface over a range of motorised applications. We have developed a system to enable the use of the same interface for synchronised motion over multiple axes using the Delta Tau PMAC controller. Details of this work will be presented, along with examples and possible future developments.
