Abstract

This thesis presents the development of a novel type of planar Penning Trap known as the Geonium Chip. The thesis describes a wide array of experimental work done in the laboratory in different topics in order to build the trap. The main focus is a detailed research of the high frequency properties of the trap and the design of new methods of detection of the trapped particles. The Geonium Chip aims at developing a practical planar, scalable Penning Trap making it suitable for new uses and technologies, such as mass spectrometry and single microwave photon detection. This thesis is mainly focussed on the high frequency properties of the trap, essential to the design of experiment and specially of the chip itself. A new trapped particle detection system is investigated, which replaces the narrow band superconducting resonator normally used in Penning trap experiments by a common SMD resistor. This represents a considerable reduction of the size of the set-up. Moreover, it is an important progress with respect to previous resonator systems, since it is able to work in a broad range of frequencies - a severe limitation of current Penning traps in applications such as mass spectrometry
