Thermal analysis of the CPFR (Confinement Physics Research Facility)/ZTH apparatus
TL;DRAbstract
The design has been completed for a new-generation Reversed-Field Pinch machine to be assembled at the Los Alamos National Laboratory during FY 1992. The Confinement Physics Research Facility (CPRF) houses the front-end ZTH torus. A series of simulations has been performed to predict temperature levels for various elements within the front end of the CPRF/ZTH apparatus for bakeout conditions and for periodic experiments. A lumped-parameter approach was used to calculate temperatures of various elements as functions of time. Results indicate that temperatures can be held at acceptable levels for 10-min cycles for the 2-MA design condition. The cycle time must be extended to approximately 13 min for 4-MA experiments. Instrumentation temperatures during bakeout were also found to be within acceptable limits. 2 refs., 7 figs., 1 tab.
