A numerical model for the calculation of pressure evolution in vacuum system has been analysed. This model simulates water desorption through the implementation of three different adsorption isotherms (Freundlich, Temkin and Sips) and hydrogen outgassing using a diffusive model. A set of experimental measurements at different temperatures have been performed on four treated stainless steel chambers. A simulation of one SPS sector has been developed to study the effect of NEG pumps installation

Abstract

A numerical model for the calculation of pressure evolution in vacuum system has been analysed. This model simulates water desorption through the implementation of three different adsorption isotherms (Freundlich, Temkin and Sips) and hydrogen outgassing using a diffusive model. A set of experimental measurements at different temperatures have been performed on four treated stainless steel chambers. A simulation of one SPS sector has been developed to study the effect of NEG pumps installation
