초록

KSTAR coils use super-conducting magnet systems. These coils operate around 4.5K and therefore require a thermal shield to reduce the heat load from outer cryostat. 80K thermal shields must be cooled by a forced flow of He gas at 20 bars without the pressure drop of 0.45 bar. Designed thermal shield shows that the pressure drop is lower than that of 0.5 bar.
