Funding: The project's funding reference is FKZ05E11CG1 The Helmholtz-Zentrum Geesthacht is operating beamlines optimized for materials research using synchrotron radiation at the Deutsches Elektronen-Synchrotron DESY in Hamburg and beamlines using neutrons at the FRM II in Munich. With the beginning of the operation of the 3rd generation synchrotron-radiation source PETRA III, Hamburg, and the design and planning of the new neutron source ESS, Lund, there is a strong demand to increase the data throughput, to make optimal use of the beamtime, together with a full controlled experiment. Especially in tomography the data pipeline from the experiment to the 3D reconstruction has to be redesigned. Furthermore, the extensive progress in hardware in recent years makes it now possible to develop nearly real time tomography experiment control system. Such system can perform all the routines that are necessary for the experiment and provide real time feedback to the user. This feedback can be used for instant monitoring and/or for real time reconstruction. The most important task for such system is the collection of the data. The data can be divided into three main groups: 1) static data; 2) data collected during the experiment; 3) persistent data. Finally all data is stored in the NeXus format. This data can be interpreted on the fly, for instance to generate a feedback or to perform a reconstruction. This system is now in an approbation stage at IBL (P05) and HEMS (P07) beamlines, PETRA III, DESY, Hamburg, Germany. |
