Realizing and tuning the largest machine ever built by the human kind, the Large Hadron Collider (LHC) at CERN, fostered a powerful challenge in advanced sensing technologies. As a matter of fact, LHC is the coldest massive site of the universe, with a vacuum level lower than free space (one tenth than the moon surface) and a temperature minor than the universe average. This target has been achieved by measuring several physical quantities in unexplored ranges, but above all by unprecedented precision.

In this talk, some of most interesting results of this technological research effort, as well as its further most recent development, are highlighted. In particular, after a short survey on sensing technologies contribution to the Higgs boson hunting, the state of the art of CERN research techniques based on wires and cryogenic dc current transformers for measuring magnetic fields and superconducting critical currents, respectively, are described.


Pasquale Arpaia took MD and PhD in Electrical Engineering at University of Napoli Federico II (Italy). He is professor of Instrumentation and Measurements at University of Sannio and Team Leader at European Organization for Nuclear Research (CERN). He was also scientific associate at Engine Institute of CNR.

He is Associate Editor of the Elsevier Journal Computer Standards & Interfaces, and in the past also of IEEE Transactions on Electronics Packaging and Manufacturing. In last years, he was scientific responsible of more than 30 awarded research projects in cooperation with industry, with related patents and licences, and funded 4 academic spin off companies. He acted as scientific evaluator in several international research call panels. He has served as organizing and scientific committee member in several IEEE and IMEKO Conferences.

His main research interests include digital instrumentation and software frameworks for measurements in particle accelerators, evolutionary diagnostics, distributed measurement systems, ADC modelling and testing. In these fields, he published 2 books, several book chapters, and more than 170 scientific papers in journals and national and international conference proceedings. His PhD students were awarded in 2006 and 2010 at IEEE I2MTC and in 2012 at IMEKO World Conferences.
