We present the design, assembly and commissioning of a modular test bench to investigate the electrical and thermal performance of aviation-relevant power cables and terminations under a wide range of steady-state or dynamic loading conditions.
Particular focus is placed on demountable custom cryogenic flanges and high current feedthroughs, providing a high degree of flexibility for the...

High-temperature superconducting (HTS) power cables are moving toward large-scale and long-distance applications, placing increasing demands on the efficiency, reliability, and maintainability of cryogenic systems. Conventional cooling architectures generally rely on centralized cryogenic stations and long-distance circulation of subcooled liquid nitrogen. As cable length increases, this...

To expand the application range of high-temperature superconducting (HTS) conductors, the transport characteristics of REBCO coated conductors were evaluated under liquid hydrogen and liquid neon cooling conditions. Although REBCO conductors maintain their superconducting state at the liquid nitrogen temperature of 77 K, their intrinsic performance cannot always be fully exploited in...

HTS applications demand Gifford-McMahon (GM) cryocoolers with higher cooling capacity and efficiency at relatively higher temperatures. HyMaster has developed a high-efficiency single-stage GM cryocooler (HMR1020) achieving 104.4 W at 20 K, corresponding to a relative Carnot efficiency (rCOP) of 11.5%. Reliability testing is performing currently being performed to ensure long-term product...

Cryocoolers are increasingly favored over bath or forced-flow cooling systems for providing heat removal and thermal stability in High Temperature Superconducting (HTS) magnets. Efficient heat transfer between coil and cryocooler is crucial to the operation of such a system. Compared to conventional thermal buses, which are typically made of solid materials such as high-purity copper braids,...

The Joule-Thomson (JT) cryocooler precooled by Gifford-Mcmahon (GM) cryocooler features high cooling efficiency and large cooling capacity, with a compact configuration, no moving parts at the cold end, and the capability for long-distance cooling power transport, making it suitable for applications such as superconducting electric levitation, gas liquefaction, and pre-cooling of...

Jurrie Bruggeman (University of Twente)28/10/2026, 13:45HTS cable developmentPoster
For models of HTS cables for large-current transfer applications, an accurate prediction of current distribution over the strands is important, as this forms the basis for many AC loss- and stability simulations. Especially in non-fully transposed multiple-strand cables, such as those of the CORC geometry, carrying a non-DC transport current, strand current distributions may be highly...

Prof. Wei Wang (Sichuan university)28/10/2026, 13:45HTS cable developmentPoster
Future electric aircraft require lightweight and high-power-density electrical transmission systems. High-temperature superconducting (HTS) cables are therefore promising for cryogenic electric propulsion, but their practical application requires coordinated evaluation of the cable, terminations, electromagnetic behaviour, and insulation. This work develops a modular single-cable cryogenic...

Because state of the art cryocoolers suffer from (CARNOT) inversion syndrome because of the 2nd law of thermodynamics wherein (heat/energy/charges) can only flow from higher to lower/charge levels, the HSS (hypersonic stochastic switch) an eigenvalue (condition of optimality in nature underscoring the power of Boltzmann “distributions” (i.e. extreme ((quantum/relativistic)) stochastic...

Cryogenic mixed-refrigerant cycles (CMRC) are a promising technology for the efficient cooling of HTS applications including power cables and current leads. Their efficiencies and lowest achievable temperatures are largely determined by the mixture composition and the heat exchanger design, both of which can be optimized using evolutionary algorithms.

Achieving hundred-watt-class cooling near 20 K is critical for the development of high-temperature superconducting (HTS) magnets, yet remains challenging for regenerative cryocoolers. This work presents recent advances at Tongji University in three pulse tube cryocooler (PTC) configurations designed to improve phase control, recover expansion power, and enhance cooling capacity.

This paper presents the development and experimental characterisation of a piezoelectric cryogenic heat switch based on mechanical contact. The switch is designed for applications requiring dynamic thermal control in the temperature range of 60--180~K, where low parasitic heat loads, compactness, and long-term stability are essential. Unlike conventional mechanical or gas-gap heat switches...

Cryogenic systems must be cooled rapidly from ambient to operating temperature and must also reject heat stably during operation. Polymer coatings are known to shorten cool-down by destabilizing the vapor film, but their behavior under operational heat load has rarely been examined. This study evaluates partial polyimide (PI) coatings in liquid nitrogen. Cylindrical specimens of SUS316L,...

Liquid hydrogen (LH2) can serve simultaneously as a fuel and a low-temperature heat sink for high-temperature superconducting devices. However, repeated testing of an LH2-cooled system is difficult because of the safety and facility requirements associated with hydrogen. This study presents a thermal-hydraulic similarity procedure for designing a liquid-nitrogen-based surrogate experiment for...
