Cooldown analysis of the toroidal field coils for the Burning Plasma Experiment (BPX)

The toroidal field (TF) coils for BPX are Bitter plate coils designed to be rapidly pulsed at high power levels, and then recooled by liquid nitrogen within an hour. The analysis of this cooldown process in support of the conceptual design of the BPX TF coils is discussed. There are two major aspect...

Zusammenfassung:The toroidal field (TF) coils for BPX are Bitter plate coils designed to be rapidly pulsed at high power levels, and then recooled by liquid nitrogen within an hour. The analysis of this cooldown process in support of the conceptual design of the BPX TF coils is discussed. There are two major aspects of the cooldown analysis: (1) the thermal conduction within the Bitter plate; and (2) two-phased nitrogen flow and heat transfer. Analysis results are presented.< >
