The neutron Electric Dipole Moment Experiment at the Spallation Neutron Source requires an overall magnetic shielding factor of order 105 to attenuate external background magnetic fields. At present, the shielding design includes an external (room-temperature) multi-layer μ-metal magnetic shield, a cryogenic (4 Kelvin) Pb superconducting shield, and a cryogenic (4 Kelvin) ferromagnetic shield composed of Metglas ribbon. This research determined how to construct a Metglas shield using minimal material that produced axial and transverse shielding factors of ~267 and ~1500. In addition, the μ-metal and Metglas shields were modeled using finite element analysis. The FEA model includes external coils and their effect on the residual magnetic fields. This study will help with the design of the shielding.

The diploma thesis deals with shielding elements in the theoretical, project and experimental level. The theoretical part describes the variants of building shading and compares individual shading elements. It explains several concepts from the field of environmental technology, which are related to the topic. The design part deals with the air conditioning of the showroom space with a specific indoor environment. The space has a flush facade, so it has a high heat load. This is a showroom for veterans, where it is necessary to maintain optimal constant hu-midity throughout the year. An air conditioning unit was designed for these needs. The experimental part describes the measurement of the values of the shielding factor of external blinds for individual slopes of slats. The measurement results are applied to the reference room and the dependence between the inclination of the slats and the energy demand for space cooling is evaluated by the software.
