Periodically the alignment of LHC collimators needs to be verified. Access for personnel is limited due to the level of radiation close to the collimators. The required measurements precision must be comparable to the other equipment in the LHC tunnel, meaning 0.15 mm in a sliding window of 200 m. Hence conventional measurements would take 4 days for a team of 3 people. This presentation covers the design, development and commissioning of a remotely controlled system able performs the same measurements in 1 h with one operator. The system includes the integration of a variety of industrial devices ranging from position sensors, inclination sensors to video cameras, all linked to a PXI system running LabVIEW. The control of the motors is done through a PLC based system. The overall performance and user experience are reported.

A high-speed data acquisition system was successfully developed and put into production in a harsh radiation environment in a couple of months to test new materials impacted by proton beams for future use in beam intercepting devices. A 4 MHz ADC with high impedance and low capacitance was used to digitize the data at a 2 MHz bandwidth. The system requirements were to design a full speed data streaming on a trigger during up to 30 ms and then reconfigure the hardware in less than 500 ms to perform a 100 Hz acquisition for 30 seconds. Experimental data were acquired, using LabVIEW real-time, relying on extensive embedded instrumentation (strain gauges and temperature sensors) and on acquisition boards hosted on a PXI crate. The data acquisition system has a dynamic range and sampling rate that are sufficient to acquire the very fast and intense shock waves generated by the impact. This presentation covers the requirements, the design, development and commissioning of the system. The overall performance, user experience and preliminary results will be reported.

The large variety of systems for the measurements of insulation, conductivity, RRR, quench performance, etc. installed at CERN’s superconducting magnet test facility generates a diversity of data formats. This mixture causes problems when the measurements need to be correlated. Each measurement application has a dedicated data analysis tool used to validate its results, but there are no generic bridge between the applications that facilitates cross analysis of mixed data and data types. Since the LHC start-up, the superconducting magnet test facility hosts new R&D measurements on a multitude of superconducting components. These results are analysed by international collaborators, which triggered a greater need to access the raw data from many typical engineering and analysis tools, such as MATLAB®, Mathcad®, DIAdem™, Excel™… This paper describes the technical solutions developed for the data formats unification and reviews the present status.
