| 1SPOr1A – Special Session: Screening Currents in HTS Magnets I | |
| Monday, Sept. 5 | 10:00 a.m. – 12:00 p.m. |
| Thanks to the effort of many material scientists and conductor manufacturers, long coated conductors became available commercially in the first decade of the 21st century, and many coils were wound with them during the last decade. Most of their target applications are NMR, MRI, or particle accelerators, and magnets for such applications must generate very precise (spatially controlled and temporally stable / controlled) magnetic fields. In 2008, it was pointed out that the large magnetization caused by screening currents, also called as shielding currents or persistent currents, can seriously deteriorate the field qualities of magnets. Since then, this screening (shielding) – current – induced field (SCIF) is one of the hot topics in the R&D of the coils wound with coated conductors.
In this special session, at first, the invited speaker will review the extensive studies made by various groups in the last eight years. Then, the latest progress on the characterizations of SCIF and the countermeasures against it will be presented in the series of contributed talks. |

| 1SPOr2A – Special Session: What will Drive Market Maturity for HTS Applications in the Electric Power Sector? | |
| Monday, Sept. 5 | 2:30 p.m. – 4:30 p.m. |
| Is cheaper and higher performance wire the key solution for energizing more HTS based electric power devices in the grid? Or is today’s wire price and performance sufficient? What are the challenges for HTS equipment to be a key solution for grid modernization efforts? These and other questions will be explored by expert panelists from around the globe in an interactive and dynamic session. Short presentations providing HTS project updates will be followed up by an expanded Q&A with the panelists. The audience will have the opportunity to ask questions and participate in real-time survey questions using a web-enabled software tool.
A 2015-2030 Roadmap document for HTS in the electric power sector was developed to outline the current state of the industry and what steps could be taken to reach market maturity. The roadmap will serve as the overview presentation for this session and set the stage for the discussion. At the end of the session, participants will have a better understanding of the challenges and needs for HTS applications in the electric power sector and how strong partnerships have developed successful projects. |

| Thursday, Sept. 8 | 3:00 p.m. – 4:30 p.m. and 4:45 p.m. – 6:15 p.m. |
|
The development of cables based on High Temperature Superconducting (HTS) materials has grown significantly in recent years. Many concepts and demonstrators have been proposed for different applications, where requirements are beyond Low Temperature Superconductors properties. The possibility to operate HTS at fields above 18 T or at high temperature is fundamental for a broad spectrum of applications, as for example in high field magnets or in power transmission cables. Different cable parameters need to be optimized for the specific application, as: engineering current density, current redistribution, AC losses, or mechanical resistance. This special session will open with an overview given by Pierluigi Bruzzone of the different cable concepts being investigated, with their pros and cons. Within the session, cable concepts based on either REBCO or BSCCO materials will be discussed. Some of the talks will focus more on cable properties, some more on specific applications of those cables. New or improved concepts with respect to the most known ones (like CORC or Roebel cables, or those based on stacks of tapes) will be introduced. We kindly invite all those interested in cable development or in applications based on HTS materials, as well as all potential users, to attend this highly interesting special session on HTS High Current Cables. |

| 5SPOr1A – Special Session: Nano-scale Artificial Pinning for High Field Application/Low Temperature Applications | |
| Friday, Sep. 9 | 8:00 a.m. – 10:00 a.m. |
| The study of pinning enhancements in superconductors has a long history. With the advent of well-connected coated conductors, much of the effort was on pinning in these complicated systems, typically at liquid nitrogen temperatures. Recently, however, interesting new work is focused at lower temperatures and higher fields. Here in this special session we focus on the nature of pinning for low temperatures and high fields, including efforts in a number of high-field relevant SC materials. | |

| TES Workshop | |
| Transition-edge sensors, or TESs, are superconducting, thermal detectors. The energy of incoming photons or particles, or the energy of a nuclear reaction within an embedded material, is converted to heat in an absorber. A TES operates in the resistive transition between its superconducting and normal-metal states, where the electrical resistance is a strong function of temperature. Thus the heat of absorption raises the device temperature and resistance. A SQUID ammeter measures changes in the device current. TESs are increasingly used in many measurement fields, including cosmic-microwave-background cosmology, X-ray and gamma-ray spectroscopy, quantum information, dark-matter searches, and measurement of the neutrino mass.
The first TES Workshop was held in 2002, with the goal that TES researchers from across the globe could share, discuss, and understand confusing experimental results from their early TESs of different geometries and materials systems. The Workshop has been held every two years since, and has been joined to the Applied Superconductivity Conference since 2008. TES devices provide interesting laboratories in which to study the nature of superconductivity itself; the Workshop has an oral and a poster session dedicated to device physics. Another pair of Workshop sessions (one oral, one poster) are about device readout: ever larger and more capable arrays of TES devices are being developed for various measurement applications, and new multiplexed readout schemes are required as an enabling technology. In a nod to the maturation of the TES field toward measurement instrumentation in an exploding number of fields, there are three oral sessions and one poster session about measurement applications. Fabrication of TES devices is covered in a Workshop poster session. Finally, an oral and a poster session are dedicated to other superconducting thermal detectors (such as magnetic calorimeters and hot-electron bolometers) that share some elements of design, physics, and readout with TESs, and are thus of interest to the TES community. Special features of the TES Workshop (outside of standard ASC conference activities) are:
