MobileCoDaC – A transportable control, data acquisition and communication infrastructure for Wendelstein 7-X

•MobileCoDaC is a transportable CoDaC infrastructure for Wendelstein 7-X.•It allows in situ testing and commissioning of components to be used at W7-X by providing W7-X CoDaC infrastructure.•It has been used successfully for test and commissioning of the HEXOS diagnostic at Forschungszentrum Jülich. MobileCoDaC is a test bed allowing in situ testing and commissioning the control and data acquisition of components to be operated at Wendelstein 7-X. It is a minimized replica of the functionality of the complete W7-X CoDaC infrastructure and can be operated independently. MobileCoDaC contains a set of W7-X CoDaC servers, network infrastructure, and accessories for remote access. All hardware is mounted in a single transportable rack system. Moreover, it provides the software infrastructure and user applications for experiment preparation, experiment operation, trouble shooting and experiment data access. MobileCoDaC has been operated successfully for test and commissioning of the control and data acquisition of the HEXOS (high efficiency extreme ultraviolet overview spectrometer) diagnostic at Forschungszentrum Jülich.
