Superconducting Devices to Test Macroscopic Quantum Coherence on the Flux States of a Rf SQUID

To perform tests of Macroscopic Quantum Coherence (MQC) on a SQUID system we have realised a set of chips containing all the different devices necessary for the measurements at a temperature of l0mK. In this paper we will report on the characteristics of all the devices in the chip as well as the measurement performed on each device. We will also describe briefly the measurements we plan to perform on the experimental apparatus.
