  摘  要:

  GEM is a delta-f gyrokinetic Particle-in-Cell code for the simulation of low-frequency phenomena in tokamak plasmas. GEM is originally developed for micro-turbulence due to ITGs, Trapped Electron Modes, Kinetic Ballooning Modes and micro-tearing modes, etc.. It is the first PIC turbulence code that has full kinetic electrons and electromagnetic effects. In recent years its application has been extended to energetic particle physics and low-n tearing modes. In this talk I will briefly describe GEM's unique algorithm for handling electrons and EM effects. I will then present some details on the code structure, input procedure and diagnostics, in the hope of removing the initial barrier a new user might face. Sample applications will be given. I will try to put GEM in the large context of important scientific computing initiatives in magnetic confinement fusion, and describe on-going or planned code development projects. Finally, I will give some advices for colleagues (theorists or experimentalists) who might be interested in using GEM in their research.
