Description

Managing the cryogenic flows inside a state-of-the-art accelerator cryomodule has become a demanding endeavor: In order to build highly efficient modules, all heat transfers are usually intercepted at various temperatures. For a multi-cavity module, operated at 2 K, this requires intercepts at 5 K and at 80 K at different locations with sometimes strongly varying heat loads which for simplicity reasons are operated in parallel. This contribution will analytically investigate the characteristics of these parallel flows, derive stability criterions and provide design suggestions.
