Mu2e

On July 14, the Mu2e Project achieved a significant milestone with the approval of Critical Decision 3, which authorizes start of full construction.

The forthcoming Mu2e experiment at Fermilab will kidnap muons and trap them in aluminum atoms. But what exactly happens when you shoot a muon at an aluminum foil? While Mu2e is under construction, its scientists are already getting some valuable answers from a smaller accomplice: AlCap.

This weekend, members of the Mu2e collaboration dug their shovels into the ground of Fermilab’s Muon Campus for the experiment that will search for the direct conversion of a muon into an electron in the hunt for new physics. For decades, the Standard Model has stood as the best explanation of the subatomic world, describing the properties of the basic building blocks of matter and the forces that govern them. However, challenges remain, including that of unifying gravity with the… More »

Researchers are one step closer to finding new physics with the completion of a harp-shaped prototype detector element for the Mu2e experiment. Mu2e will look for the conversion of a muon to only an electron (with no other particles emitted) — something predicted but never before seen. This experiment will help scientists better understand how these heavy cousins of the electron decay. A successful sighting would bring us nearer to a unifying theory of the four forces of nature.

Mau Lopes has never waited as anxiously for a package as he did for the one that arrived late last month. From the Italian laboratory INFN-Genoa came the completed prototype of one coil module for the s-shaped Mu2e transport solenoid. The module is an aluminum ring about a meter wide and a meter deep, wound with hundreds of turns of superconducting cable. Twenty-seven modules joined together will generate the magnetic field that forms the experiment’s winding muon path. As a… More »
