A software framework for flexible magnetic measurements at CERN

Abstract

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, and verify identification and validation uncertainty. An actual case study on the dynamic metrological characterization of a Fast Digital Integrator for highperformance magnetic measurements at European Organization for Nuclear Research (CERN) is presented.

Advanced User Interface Generation in the Software Framework for Magnetic Measurements at Cern

“…In particular, the test of the about 8,000 LHC superconducting magnets working at 8.3 T and 1.2 K, stimulated new stricter requirements for magnetic measurement software. The Flexible Framework for Magnetic Measurements (FFMM) was designed at CERN in cooperation with the University of Sannio [19] to satisfy a wide range of measurement requirements and to integrate more performing flexible hardware [26]. FFMM is a software platform under development aimed at generating in a systematic way all the measurement software applications for testing the particle accelerator magnets.…”

“…In this case, test engineers are responsible for preparing test scripts [19], where the interaction between measurement application and final user are described at high level [3], without any indication of GUI aspects.…”

“…As an example, if the test engineer needs for asking as input an integer value at runtime, he will use the capture method of a GIC object in the measurement script [19]: − Def GIC "InputParam". By inserting in the script only these instructions, a form is displayed, and the value entered by the user is stored in the variable pointed.…”

A Petri Net-Based Software Synchronizer for Automatic Measurement Systems

“…The proposed Synchronizer was experimented at CERN, inside a research project carried out in cooperation with the University of Sannio, aimed at realizing a software framework for supporting a test engineer in developing automatic measurement applications in magnetic testing [23].…”

“…In particular, in Section II, the basic ideas and the design of the Synchronizer are highlighted with a straightforward example. In Section III, an experimental case study on the software framework for magnetic measurements [23], [24] at the European Organization for Nuclear Research (CERN) is reported.…”
