    "abstract": "Measurements and numerical simulations on the charge transfer in Gas Electron\nMultiplier (GEM) foils are presented and their implications for the usage of\nGEM foils in Time Projection Chambers are discussed. A small test chamber has\nbeen constructed and operated with up to three GEM foils. The charge transfer\nparameters derived from the electrical currents monitored during the\nirradiation with an Fe-55 source are compared with numerical simulations. The\nperformance in magnetic fields up to 2 T is also investigated.",
