690. Thermal characteristics of JT-60SA thermal shield (FRI-OR7-801-02)

Kyohei Natsume (National Institutes for Quantum and Radiological Science and Technology)

Oral

JT-60SA is a superconducting tokamak constructed in a project being undertaken jointly by Japan and Europe. The thermal shield provides screening of the superconducting coils from the plasma vacuum vessel at elevated temperature and the tokamak cryostat at ambient temperatures. The thermal shield is made of stainless steel plates and is cooled by helium gas which flows in embedded pipes along...

171. Feasibility of different cryogenic systems for ReBCO coils based high-dynamic superconducting actuators (FRI-OR7-801-03)

Mr Jeroen ter Harmsel (University of Twente)

Oral

We present a systematic design approach to the cryogenic system of ReBCO coated conductor based high-temperature superconducting actuators used in highly dynamic applications. While ReBCO coils operating around 20 K can in principle increase the force-density of linear actuators by nearly a decade, the thermal design of such a system poses two important challenges. First, the foreseen AC loss...

930. Design and experimental investigations on the helium circulating cooling system operating at around 20 K for a 10-Mvar class HTS dynamic synchronous condenser (FRI-OR7-801-04)

Oral

A project to develop a 10-Mvar high temperature-superconducting (HTS) dynamic synchronous condenser is carried out by China Southern Power Grid Corporation. In order to cool the magnets to 20-30 K, a set of cryogenic system using circulating helium as the working fluid was developed, and it has been coupled and tested with the 10-Mvar class dynamic synchronous condenser. Six cryogenic coolers...
