A model for global Alfvén eigenmodes (GAE) in a screw pinch plasma geometry is presented. The wave equations are derived from an ideal magnetohydrodynamic (MHD) model with corrections for finite frequency. Analytical and numerical solutions of these equations, applied to parameter sets approximating the TORTUS Tokamak and the Wendelstein WVII-AS Advanced Stellarator, are presented and discussed.
