Fusion Magnets
Date: Saturday, October 24, 2020
Time: 9:00 a.m. – 10:30 a.m. (EDT)
Cost: $50 Students / $75 Regular and Retiree
Description: The aim of this short course is to provide an overview upon the main magnet systems deployed in magnetic confinement fusion devices of the tokamak type. By starting from the basic scaling laws linking plasma performances to magnetic field intensity, the main design philosophies and architectures of present and future tokamak magnet systems will be reviewed. Following this general overview, the attention will be focused on the functions and criteria adopted in the ITER project to design the toroidal and poloidal field magnet systems. Mechanical as well as superconducting design features will be described in detail to highlight the intimate inter-link between these two aspects and how they differentiate between the toroidal and the poloidal field system. To conclude, few design examples will be illustrated step by step to improve the attendee’s understanding of the basic concepts discussed.

High Temperature Superconducting Materials and Magnet Technologies
Date: Sunday, October 25, 2020
Time: 8:00 a.m. – 11:00 a.m. (EDT)
Cost: $50 Students / $75 Regular and Retiree
Description: After three decades of arduous development, three high-Tc cuprate materials have been developed into long-length composite conductors with high critical current density at magnetic fields or temperatures beyond the reach of Nb-Ti and Nb3Sn materials. Applications are emerging, including magnets for >1 GHz NMR spectroscopy, high-field fusions, and the next generation of high energy particle colliders. In this course we will learn the design, fabrication, electromagnetic properties, and practical engineering properties of state-of-the-art high-temperature superconducting tape, wire, and cable conductors. We will also review and discuss the design and key aspects of HTS magnet technologies, including magnetization and shielding current effects, quench detection and protection, and management of stress and strains.

Cost: $50 Students / $75 Regular and Retiree
Description: This short course will first provide an overview of the thermal and mechanical properties of cryogenic helium in both the classical liquid phase (He I) and the superfluid phase (He II). Their applications in cooling various scientific and engineering equipment, especially superconducting magnets and devices, will be outlined. Then, the unique thermal counterflow heat transfer mode in He II will be discussed in detail, and a two-fluid model will be presented to explain the various unconventional thermal and hydrodynamic behaviors of He II. Example problems relevant to the design of He II based cooling systems will be discussed.

Description:
Technology roadmapping helped the semiconductor community to successfully coordinate research and development efforts for over two decades. In 2018, Cryogenic Electronics and Quantum Information Processing (CEQIP) became an international focus team (IFT) within the International Roadmap for Devices and Systems (IRDS). The updated roadmapping process is driven both bottom-up by devices and top-down by systems application requirements. Models, metrics, and benchmarks predict device and system performance and guide technology roadmapping to meet application requirements. The 2020 report [1] included the first roadmaps for superconductor electronics.
The goal of the workshop is to identify and discuss areas needing improvement in the 2021 report. Examples include metrics for logic family comparisons, future device roadmaps, group forecasting processes, and how to incorporate economic drivers. The workshop is open to all who are interested.
