2019 CEC and ICMC Joint Symposium: Transportation
Alternative propulsion technologies including electric-drive are increasingly being developed and utilized for almost every major transportation industry. For the aerospace industry, nearly exponential growth is occurring recently for electric propulsion, with reportedly with more than 300 startup companies worldwide, and supported by Airbus, Boeing, Embraer, Rolls Royce, Uber, Google, Intel, and others. A 6-9 passenger aircraft being developed by Eviation will fly 650 miles, which exceeds the range of more than 50% of 4.5 Billion flights worldwide. Electric propulsion offers immediate advantages for aviation including 6-10x lower energy-use and operational costs, and will enable development of new industries such as inter-city transport between regional/local hubs by vertical-take-off-lift (VTOL). For industries such as aerospace that are especially sensitive to size-weight-and-power-loss (SWaP), the development of cryogenic electric-power drivetrains is expected to provide significant advantages and system-level benefits.
The 2019 CEC-ICMC conference is providing this joint CEC and ICMC symposium to consider all aspects of cryogenic transportation technologies, including electric drivetrain components/machines, cryogenic cooling and ancillary technologies, and system-level-integration issues and impacts. The symposium will cover 2.5 days with over 25 invited presentations, with subtopics of motors/generators, power electronics, and cables and AC loss. A special overview session will take place on Wednesday, July 24, from 4:15 p.m. to 6:20 p.m., also covering hydrogen technologies.
2019 CEC-ICMC Joint Overview Session: Superconducting Devices for Quantum Information Processing
During the last ten years, superconducting circuits have passed from being interesting physical devices to becoming contenders for near-future useful and scalable quantum information processing. The inherent quantum supremacy provides unprecedented possibilities that are well beyond the capability of classical supercomputers. Among the recent development of superconducting devices, systems and applications, Josephson junction based superconducting devices have emerged as a leading physical platform for future quantum information technology, particularly in quantum computation. Fabricated with conventional superconductors on crystalline substrates, these devices operate near their quantum ground states at temperature of less than 50 mK, and requires exquisite material quality, thermalization, shielding, and microwave control pulses. QIS systems based on superconducting technology have many advantages, and the quantum circuits, quantum cavities, and quantum memories associated with them have well established needs for cryogenics, cryogenic materials, and, in some cases, cryogenic cavities. In this special joint overview session, speakers from leading research labs will present the latest advances in quantum information science and technologies being explored and developed with superconducting devices.
The 2019 CEC-ICMC conference is providing, for the first time, this joint CEC-ICMC special overview session to the conference participants on Wednesday, July 24 from 4:15 p.m. to 6:15 p.m. We look forward to your participation in this session and hope the session will be beneficial to you in terms of gaining a better and deeper understanding of the subject and make connection to your current and future effort and endeavor in your specialty areas.
An informal workshop consisting of brief presentations and discussions of ongoing and planned worldwide digital library and database efforts related to cryogenic materials has been organized by ICMC. The practicality and synergistic possibilities related to the establishment of an international cryogenic materials library and database are being considered by ICMC. The special workshop is being held to learn of other digital data storage and retrieval activities that include materials at low temperatures. The new European initiative (FuSuMatech) related to applied superconductivity is discussed. Other topics presented include the NIST correlated low-temperature thermophysical properties database, past ICMC conference proceedings digitally stored by SpringerMaterials, the IEEE History Center, CSA’s Cryogenic Treatment Data Center, digital material data-management strategies developed at NIST, database activities in Japan and for high-field superconducting magnet design and development (National High Magnetic Field Laboratory). Current ICMC low-temperature library and database efforts will also be presented.
The workshop will be held on Wednesday, July 24, from 2:00 p.m. to 5:00 p.m. Nine speakers will provide brief presentations with discussion during and after each. Conference participants are welcome to attend and present questions/comments during the general discussion periods.
Latest Development in Flux Pinning Highlight
Pinning of quantized magnetic vortices in superconductors enables high critical current densities by orders of magnitudes at applied magnetic fields up to few to tens of Tesla, which are demanded for practical applications, such as large magnets, rotary machines (motors and generators), devices/systems for power grids (cables, fault current limiters, transformers), to name a few. The recent progress in nanoscience and nanotechnology has prompted tremendous success in enhancing pinning force density and efficiency through various novel approaches in terms of generation of artificial pinning centers with precisely controlled dimension, morphology, orientation and concentration. This focus session of the Latest Development in Flux Pinning Highlight intends to provide a platform for updates of the recent progress made and the critical issues still remained, as well as for stimulating fruitful discussions, generating new ideas, and strengthening and/or establishing existing and/or new collaborations in this important field.
SRF Materials – Fundamental Developments in Characterization and Analysis
Superconducting RF (SRF) cavities are key components of modern particle accelerators such as free electron lasers (E-XFEL and LCLS-II), electron-ion colliders (e-RHIC and BNL), and electron-positron colliders (ILC). Currently, the material of choice for high-performance SRF applications is pure Nb, with surface doping. The current maturity of SRF Nb has been possible due to the fundamental understanding of surface and bulk properties of this system. The sessions build on some of the recent results, and ongoing research efforts involving a fundamental understanding of Nb, and other potential materials for SRF applications. More recently, the potential of using SRF technology for dark matter detection and quantum computing is under investigation. Discussions during the sessions will cover these topics as well.
REBCO Coated Conductors
REBCO coated conductors are now manufactured by over a dozen companies world-wide. Since the first demonstration of pilot manufacturing of REBCO coated conductors for delivery of 10,000 meters for the Albany Cable Project in 2006, substantial progress has been made to produce longer tapes with better performance and uniformity. New methods have been developed for higher throughput, improved critical currents in high magnetic fields, superior mechanical properties, in-line quality control and rapid reel-to-reel testing. Leaders from several companies and research institutions developing and manufacturing REBCO coated conductors will present the latest advances in their technologies in this special session at the CEC-ICMC.
