Innovative Methodology Dedicated to the CERN LHC Cryogenic Valves Based on Modern Algorithm for Fault Detection and Predictive Diagnostics / Pezzetti, Marco (CERN) ; Amodio, Alessio (CERN) ; Arpaia, Pasquale (CERN) ; Donon, Yann (CERN) ; Gargiulo, Federico (CERN) ; Iodice, Luca (CERN)
The European Organization for Nuclear Research (CERN) cryogenic infrastructure is composed of many equipment, among them there are the cryogenic valves widely used in the Large Hadron Collider (LHC) cryogenic facility. At present time, diagnostic solutions that can be integrated into the process control systems, capable to identify leak failures in valves bellows, are not available. [...]

A Static-Sample Magnetometer for Characterizing Weak Magnetic Materials / Arpaia, Pasquale (Naples U.) ; Buzio, Marco (CERN) ; Parrella, Alessandro (CERN) ; Pentella, Mariano (CERN) ; Ramos, Pedro M (Lisbon, IST)
In this article, a static-sample magnetometer is presented to measure the relative permeability of weakly magnetic materials. The method consists of scanning the magnetic field inside a dipole magnet by using an NMR teslameter to measure the perturbation of a test specimen on the externally applied field. Then, an inverse problem is used to compute the specimen’s relative permeability. [...]

Drift-Free Integration in Inductive Magnetic Field Measurements Achieved by Kalman Filtering / Arpaia, Pasquale (Naples U.) ; Buzio, Marco (CERN) ; Di Capua, Vincenzo (Naples U. ; CERN) ; Grassini, Sabrina (Turin Polytechnic) ; Parvis, Marco (Polytech. Turin) ; Pentella, Mariano (CERN ; Turin Polytechnic)
Sensing coils are inductive sensors commonly used to measure magnetic fields, such as those generated by electromagnets used in many kinds of industrial and scientific applications. Inductive sensors rely on integrating the output voltage at the coil’s terminals in order to obtain flux linkage, which may suffer from the magnification of low-frequency noise resulting in a drifting integrated signal.

Hysteresis Modeling in Iron-Dominated Magnets Based on a Multi-Layered NARX Neural Network Approach / Amodeo, Maria (CERN ; Turin Polytechnic ; U. Naples (main)) ; Arpaia, Pasquale (CERN ; U. Naples (main)) ; Buzio, Marco (CERN) ; Di Capua, Vincenzo (CERN ; U. Naples (main)) ; Donnarumma, Francesco (CNR, Italy)
A full-fledged neural network modeling, based on a Multi-layered Nonlinear Autoregressive Exogenous Neural Network (NARX) architecture, is proposed for quasi-static and dynamic hysteresis loops, one of the most challenging topics for computational magnetism. This modeling approach overcomes drawbacks in attaining better than percent-level accuracy of classical and recent approaches for accelerator magnets, that combine hybridization of standard hysteretic models and neural network architectures.
