Physicists call it the Standard Model. It’s a theory which describes the best current understanding of the building blocks of matter and their presumed interactions. But it’s discoveries well beyond the scope of the Standard Model’s framework which scientists hope will answer some the fundamental questions about matter.
To do it, the science community is examining a Great Triumvirate of sorts: insights and observations from three frontiers grouped under the umbrellas of Cosmic, Energy, and Intensity studies.
Now those scientists are looking for keystones in the Intensity Frontier via the study of exceptionally rare processes like what’s known as “muon-to-electron conversion.” It’s an ideal problem for them to examine why particles in the same category decay from heavy to lighter, more stable mass states, and physicists have pondered the issue since the 1940s.
Very simply put, electrons are all about action; action like lighting a home or powering a computer. Muons, on the other hand, are “heavier” forms of electrons, but it’s not clear what their relationship to electrons may be, and understanding the relationship is key to understanding electrons.
A group of researchers working what they call the Mu2e tracker — a device composed of tiny, low-powered circuit boards which sit at the end of “straws” — has only a limited space to include cooling lines. The cooling lines are key to the operation as they wick away heat that would otherwise sit in a needed vacuum.
One major hurdle they had to overcome is that machining the curved metal parts with elongated holes to hold the straws was, until now, difficult and expensive. But by utilizing 3D printing to make a high-tech, transparent plastic version, those issues have been largely addressed.
The researchers plan to use a prototype of 3D printed plastic to run a current through the straw and a magnet to “pluck” the straw in the same way a guitar might be strummed. It’s by measuring the resulting vibration that they can set a benchmark to keep the straw straight during the entire lifetime of the experiment.
The idea of the Mu2e project is track the actual conversion of a muon to only an electron without the emission of additional particles. Physicists have predicted that it’s possible, but they’ve never actually seen it occur.
This experiment needs to be some 10,000 times more sensitive than other experiments in the past to track the fast-moving electrons to detect the signature 105 MeV output which would prove muon decay.
In practice, it means the designers working on the Mu2e project need to create a detector which includes very little material — so little, in fact, that it borders on being “nothing” in relative terms.
“You want to detect the electron with nothing – and this is as close to nothing as we can get,” says Vadim Rusu of the Department of Energy’s Fermilab.
The tracker itself is made from thin straws of metalized Mylar, and at only 15 microns thick, they represent the thinnest straws ever used in a particle physics experiment.
The straws are filled with argon and carbon dioxide gas and include a thin wire which runs down the center of the straw. Circuit boards at both ends of the straws are set to gather any electrical signal produced as electrons hit the gas inside the straw, and Rusu says they’ll measure the arrival times at each end of the wire to plot the electron’s overall trajectory.
