  1. Vasily Dzhordzhadze Monopole Group Meeting, BNL July 26, 2007 Run7 Monopole Test Experiment (Summary)

  2. Outline • Introduction • Run7 – Monopole Test Experiment • Results • Future experiments (Run8 and Run 9) • Summary

  3. September 2006 PAC Recommendations • 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. http://www.bnl.gov/npp/docs/pac0906/chaudhari_Monopole-RHICPAC.pdf

  26. Future RHIC Runs (8 and 9) Years 2007-2008 2008-2009 d-Au Au-Au Peak L 40 40 s(95%) = 3/(eLdt) = 5.5 x 10-32

  27. 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
