Rotating coils, flux metric method, wire systems
/ Fiscarelli, Lucio (speaker) (CERN)
The measurement of the magnetic field is often the final verification of the design and fabrication process of a magnets for particle accelerators.
In most cases, when seeking high accuracy, the measurement technique and its realization can result in a considerable effort. The lecture describes
the most used field-measurement techniques based of flux-metric methods:
i)the rotating coil method gives a complete two-dimensional description of the magnetic field in terms of normal and skew multipoles;
ii) static coils are employed in case of fast-ramped or curved magnets;
iii) the single stretched wire is the reference instrument to measure field
integrals and to find the magnetic axis..

Electrical Insulation for Magnets
/ Piccin, Roland (speaker) (CERN)
Magnets for particle accelerators are electrical machines subjected to severe operating conditions such as extreme temperatures, radiations, high mechanical stresses, and in certain cases high voltages. A robust electrical insulation is vital to guarantee a high reliability and availability of the accelerator machines. [...]

Quench detection & magnet protection
/ Todesco, Ezio (speaker) (CERN)
When a superconducting magnet has a local irreversible transition above the critical surface (quench), protection systems must be activated to avoid overheating the conductor or creating too large voltages in the coil between the resistive part the the superconductive one. Here we will deal with protection of high field main accelerator magnets, characterised by a large current density and long lengths, not allowing energy extraction. [...]

Technical superconductors (HTS)
/ Ballarino, Amalia (speaker) (CERN)
After a short introduction aiming at reviewing the physical parameters of superconducting materials, families of the cuprates (REBCO, BSCCO 2212 and BSCCO 2223), MgB2 and Iron Based Superconductors are described. Emphasis is put on their structure, on their physical properties, including vortex pinning characteristics, and on the manufacturing processes that enable production of wire and/or tape. [...]
