Muon g-2 milestones

It’s a busy summer — and not only for the neutrino community. The Muon g-2 experiment passed another milestone last week when its superconducting magnet finally moved into the experimental hall on the Muon Campus. The move went flawlessly, and the magnet is now being prepared for operation. The hall will continue to be a hive of activity over the next few weeks, with engineers and technicians carefully placing the magnet in its final data-taking configuration on top of a steel support ring. The next steps include completing the cryogenic system, connecting the magnet to the liquid-helium source and preparing the power supplies. The schedule calls for cool-down early in 2015.

The Muon g-2 project was also reviewed last week by the DOE Office of Project Assessment. This formal review process culminates in establishing a baseline cost and schedule (CD-2) for the project as well as a start for construction (CD-3). The three-day review here at the laboratory went well, and the project is expected to meet all the requirements early next year once the magnet is cold, a precondition for receiving CD-2/3. Congratulations to the project team, spokespeople and collaboration.

Even with all these milestones, there is much work to do before the experiment starts taking data in 2017. The enthusiasm of the young collaboration members is as intense as ever. Their excitement comes from the goal of being able to make the world’s best precision measurement of the anomalous magnet moment of the muon. Once the measurement is compared to theory, we will know if new physics beyond the Standard Model is present.
