Control system standards for the Diamond synchrotron light source were initially developed in 2003. They were largely based on Linux, EPICS and VME and were applied fairly consistently across the three accelerators and first twenty photon beamlines. With funding for further photon beamlines in 2011 the opportunity was taken to redefine the standards to be largely based on Linux, EPICS, PC’s and Ethernet. The developments associated with this will be presented, together with solutions being developed for requirements that fall outside the standards.

High Speed Detectors: Problems and Solutions

Diamond has an increasing number of high speed detectors primarily used on Macromolecular Crystallography, Small Angle X-Ray Scattering and Tomography beamlines. Recently, the performance requirements have exceeded the performance available from a single threaded writing process on our Lustre parallel file system, so we have had to investigate other file systems and ways of parallelising the data flow to mitigate this. We report on the some comparative tests between Lustre and GPFS, and some work we have been leading to enhance the HDF5 library to add features that simplify the parallel writing problem.
