Beschreibung:
For nanoparticle research, a Halbach array device has been developed that allows the dynamic reproducible definition of the magnet field strength and orientation at a sample. The maximum achievable field strength is 0.5 Tesla. The main application of the Halbach array will be in the sample environment of the GISAXS instrument GALAXI.The magnet field orientation and strength are defined by rotating permanent magnets with stepper motors. Control of the stepper motors is implemented with a S7-1500 PLC in the ET200SP form factor. All field computations are executed in Nicos which controls the device. One challenge in development is the dynamic positioning of magnets due to changing forces. For vacuum applications, a water-cooling system has been implemented that allows the control of the motor temperatures. Design and implementation of the Halbach array device as well as future plans will be presented.
