Abstract
A key feature of the cryogenic system for the proposed TeV Superconducting Linear Accelerator (TESLA) is a He II two-phase flow line that provides cooling for the superconducting RF cavities. Understanding the behavior of this line is vital to the proper functioning of the accelerator. A numerical model has been developed that allows predictions of the pressure, temperature and mass flow rates of the components in the twophase line and in the connected gas return line. The model also predicts the helium level in the two-phase line. This is a rigorous model using the conservation laws of mass, momentum and energy for each phase and allowing for interactions between the phases and the walls as well as between each other. The model also takes into account the specific geometry of the TESLA cooling system. This paper describes the model and presents its predictions for two alternative cooling schemes.
