  • Future experiments (Run8 and Run 9)

  • Summary

  • Motivation

    The observation of a magnetic monopole would be a profound discovery in physics. However, it is very important to compare the goals of the proposed experiment with what has already been achieved in earlier experiments, for example at FNAL, in a more complete fashion than in the present proposal.

  • Experiment

    Since there is little experience with the operation of a SQUID detector in the environment of a RHIC experiment, some experimental tests would be extremely valuable and should be carried out by the proponents. The results could well lead to modifications of the experimental design or to reevaluations of the sensitivity of the search.

Summary
Summary

  • Test Run was successful

  • SQUIDs and Gradiometers behavior is independent from RHIC beam

  • Devices picking up noises from RHIC

  • Perfect Shielding needs to be designed

  • What will be noise when we open the pipe and how to protect devices?

  • Looking forward for DoE approval
