A fast digital integrator (FDI) with dynamic accuracy and a trigger frequency higher than those of a portable digital integrator (PDI), which is a state-of-the-art instrument for magnetic measurements based on rotating coils, was developed for analyzing superconducting magnets in particle accelerators. Results of static and dynamic metrological(More)
This paper proposes an automatic test bench, based on a rigorous and repeatable measurement procedure, for the analysis of a position sensor linear variable differential transformer (LVDT). The test bench allows complete characterization of an LVDT sensor working in an interfering magnetic field by evaluating the uncertainty and nonlinearity of the sensor.(More)
FLUKA Monte Carlo simulations have been performed to identify particle energy spectra and fluences relevant for evaluating the risk of single event effects in electronics installed in critical LHC underground areas. Since these simulations are associated with significant uncertainties, the results will compared with an online monitoring system installed to(More)
An Aspect-Oriented approach to software synchronization in automatic measurement systems is proposed. Tasks are synchronized by means of “aspects”, a specific software unit to better modularize properties and features transversal to many modules (“crosscutting concerns”). In this way, maintainability and reusability of a measurement software are improved:(More)
An Aspect Oriented approach to implement fault detection in automatic measurement systems is proposed. Faults are handled by means of “aspects”, a specific software unit to better modularize issues transversal to many modules (“crosscutting concerns”). In this way, maintainability and reusability of a measurement software are improved: indeed, once a(More)
A statistical behavioral modeling approach for assessing dynamic metrological performance during the concept design of accurate digitizers is proposed. A surface-response approach based on statistical experiment design is exploited in order to avoid unrealistic hypothesis of linearity, optimize simulation effort, explore systematically operating conditions,(More)
