Abstract

Monitoring the magnetic axis misalignment in particle accelerator solenoids

The lecture will describe the work carried out in the framework of the ELI-NP (Extreme Light Infrastructure – Nuclear Physics), to design a measurement method for monitoring the misalignment of the magnetic axis in solenoids used as focusing devices in particle accelerators.
In particular, in the first part, the motivation of the work will be given, by giving some hints about the usage of the solenoids in particle accelerators. Some details about the measurement of the magnetic axis of solenoids will be given and the need of monitoring the axis during the magnet working will be motivated.
Then, a method for the monitoring of the magnetic axis misalignment will be described, able to operate during the magnet working. In particular, a first version of the method, to be applied in the case of single-coil solenoids, will be described; a second version of the method will be also formulated to be used in multi-coil solenoids.

He received the National Academic Qualification as an Associate Professor and as Full Professor, in 2013 and 2018, respectively. Since 2015, he collaborates with the European Organization for Nuclear Research (CERN), Geneva, Switzerland, first as visiting scientist, and then as cooperation associate, working on magnet characterization, with the Magnetic Measurement Section (TE-MSC-MM), on diagnostics of cryogenic processes, with the Controls and Electrical Support Section (TE-CRG-CE), and on the characterization of RF cavities with the Hadron Synchrotrons Coherent effects Section (BE-ABP-HSC). Since June 2016 he is associated to the National Institute of Nuclear Physics (INFN) and collaborates to the ELI-NP (Extreme Light Infrastructure - Nuclear Physics) project.
He is Editor of the ELSEVIER Measurement journal.
He is member of the IEEE since 2010, and is member of the IEEE Instrumentation and Measurement Society (IMS), the IEEE Aerospace and Electronic System Society, and of the IEEE Standards Association. He is Senior Member of the IEEE since 2012. He is Chapter Chair Liaison of the IEEE IMS.
He is member of the Armed Forces Communication and Electronics Association (AFCEA) and is Young President of the AFCEA Naples Charter.
He has published more than 110 papers on international journals and conference proceedings, mainly dealing with measurements for telecommunications, data converter testing and biomedical instrumentation.
