  This paper presents the involvement of Diamond Light Source (DLS) with the open source community, the Eclipse Science Working Group and how DLS is changing to share software development effort better between groups. The paper explains moving from product-based to bundle-based software development process which lowers reinvention, increases reuse and reduces software development and support costs. This paper details specific ways in which DLS are engaging with the open source community and changing the way that research institutions deliver open source code.

  The high data rates produced by the latest generation of detectors, more efficient sample handling hardware and ever more remote users of the beamlines at Diamond Light Source require improved data reduction and data analysis techniques to maximize their benefit to scientists. In this paper some of the experiment data reduction and analysis steps are described, including real time image analysis with DIALS, our Fast DP and xia2-based data reduction pipelines, and Fast EP phasing and Dimple difference map calculation pipelines that aim to rapidly provide feedback about the recently completed experiment. SynchWeb, an interface to an open source laboratory information management system called ISPyB (co-developed at Diamond and the ESRF), provides a modern, flexible framework for managing samples and visualizing the data from all of these experiments and analyses, including plots, images, and tables of the analysed and reduced data, as well as showing experimental metadata, sample information.

  Many synchrotron beamlines offer some form of continuous scanning for either energy scanning or sample mapping. However, this is normally done on an ad-hoc beamline by beamline basis. Diamond has recently embarked on an ambitious project to define how to implement continuous scanning as the standard way of doing virtually all mapping tasks on beamlines. The project is split into four main areas: 1) User interfaces to describe the mapping process in a scientifically relevant way, generating a scan description that can be used later; 2) The physical process of scanning and coordinating hardware motion and detector data capture across the beamline; 3) Capture of the detector data and all the associated meta-data to disk. Deciding and describing the layout of the file (or files) for the main use cases; 4) Display and analysis of live data and display of processed data. In order to achieve this common approach across beamlines, the standard software used throughout the facility (Delta Tau motor controllers, EPICS, GDA and DAWN), has been built on.
