Abstract :
The floating wire (FW) technique was applied to determine particle trajectories in three dipoles which form the magnetic spectrometer ANKE installed in the accelerator ring COSY Juelich. Methodical improvements of the well-known FW technique result in extended applicability and high accuracy. The FW measurements compare well with field map based trajectory calculation using the GEANT code.
