We develop a Penning trap image current detection systems including a cyclotron detection system. The image current detection systems which I developed and tested are made up of superconducting toroidal coils and cryogenic amplifiers. As a result, I was able to achieve a higher Q-value with toroidal coils than we had previously achieved using solenoids.
