On On the development and construction of the Double-Flux Concentrator Trap

Bachelor thesis | Natuurkunde (BSc)

To study gravity on the quantum scale, highly isolated systems are necessary. These systems can be created by levitating small particles. This thesis documents a project in which we attempt to design a magnetic levitation trap using two flux concentrator coils in an anti-Meissner orientation to levitate 50 µm microspheres. A sample holder is designed which ensures the proper alignment of the coils and thermalization of all the superconducting components using a copper base and top plate. We did not manage to successfully levitate the microsphere, because the microsphere itself most likely does not reach the right temperature for it to become superconducting. However, we do succeed at consistently sending high currents (600 mA) into a flow cryostat without breaking the superconducting state of the coils. This proves that the trap has the potential to become successful.
