Description
Summary:Poloidal limiters are required on the Tokamak Physics Experiment (TPX) for startup and to provide protection to the RF antennas. This paper discusses the conceptual design of these limiters and the analyses associated with the design. The configuration of the limiters is described and includes the carbon-carbon (C-C) tile design and their attachment concept. The thermal response of the limiters to startup and steady state plasma conditions is discussed. The required water coolant flow rates and resulting pressure drops are presented. The structural response of the limiter to both halo and eddy current disruption conditions is also included.
