The purpose of this research is to realize a micro actuator which can be driven under a cryogenic and high intensity magnetic field. In this study, the target is the material, structure and modeling for the actuator. For the realization of the actuator which has not a temperature dependency for the driving, a bolt-clamped Lngevin type transducer has been designed and evaluated. Using a finite element method, the temperature dependency has been evaluated about the transducer. Non-linear parameters about material properties were used for the simulation. As a result, the transducer which has not a temperature dependency for pre-load setting has been obtained by the simulation. The fabricated transducer under the design has been evaluated and used for the driving of the actuator. The transducer has successfully driven the actuator without the temperature dependency for the setting.
