| Abstract |
A discharge or RF-breakdown event in a CLIC acceleration structure causes the localized release of gas molecules inside a thin conduction limited system with distributed pumping. We discuss the transient behavior of such a system in the molecular flow regime that allows an analytical solution with the help of Greens functions. They describe the temporal evolution of the gas density and the gas flow ejected from the ends of thin pipes of finite length. Distributed pumping, for example through the HOM damping slits is taken into account.
