Digging begins for Muon g-2 and Mu2e beamlines

Fermilab has begun construction on new beamlines for its muon programs, Muon g-2 and Mu2e. Image: Fermilab

Editor's note: The construction of the beamlines for Fermilab's muon experiments necessitates the closure of part of Kautz Road. See the Dec. 8 issue of Fermilab Today for more about the road closure.

This month construction has commenced on beamline tunnel extensions for Fermilab's two muon experiments, Mu2e and Muon g-2.

In the area of the current Delivery Ring (the former Antiproton Debuncher), southwest of the Booster, the existing beam tunnel will be extended approximately 200 feet, at which point it will branch in two separate directions. The Muon g-2 tunnel, about 75 feet long, will terminate in the MC-1 Building, which houses the experiment's muon storage ring. The Mu2e tunnel, around 550 feet long, will head toward a new building to be constructed for the experiment. Construction is expected to take one year. The start of the construction of the Mu2e building is planned for 2015.

Digging for the tunnels began this month. Part of Kautz Road will become permanently inaccessible, with a detour from South Booster Road and Indian Creek Road serving as the new road.

Fermilab Accelerator Division physicist Mary Convery, who oversees the Muon Campus program, coordinated the tunnel designs with Tom Lackowski, project manager; Rod Jedziniak, project design coordinator; and Tim Trout, project construction coordinator, all of FESS.

The primary challenge in constructing the beamlines will be in accommodating fixed features and structures, both man-made and natural.

"The locations of the g-2 and Mu2e buildings were fairly fixed because there are already utility corridors underground," Convery said. "There are also wetlands that we are trying not to disturb."

Convery said that these physical constraints were important considerations in designing the experiments' beamlines, since the space available to accomplish the necessary beam manipulations was limited.

"It is not only the geometry of the beamlines that we have to conform to," Lackowski said. "We also have to make sure the many services — the cable trays and the water services for cooling — are all coordinated."

Because the two muon experiments use the same beamlines at different energies, they cannot be run simultaneously.

For both experiments, protons will proceed through the Linac, course through the Booster and then travel through the Recycler. A set of beamlines connects the Recycler to the Muon Campus. For the Muon g-2 experiment, the proton beam hits a target, converting the beam to a mixture of pions, protons and muons. The particles circle the Muon Delivery Ring several times, where protons are then removed and the remaining pions decay into muons. When the Muon g-2 experiment is taking data, the muon beam will continue to the experiment in the MC-1 Building.

In contrast, for the Mu2e experiment, the protons bypass the target station and are transported to the Delivery Ring. The Mu2e protons also circle the Delivery Ring, then continue as an all-proton beam to the target in the Mu2e building area.

Convery says work is also being done on other technical upgrades, such as installing magnets, along the beamline route.

She expects the Muon g-2 experiment to begin in 2017, with Mu2e starting later, as scheduled.

"Fermilab people have worked together for many years on various beamline projects," Lackowski said. "We have had a very tight relationship with Mary and other colleagues, so we believe the Muon Campus tunnel project will go well."

European probe shoots down dark-matter claims

From Nature, Dec. 2, 2014

The first full analysis of the data gathered by the European Space Agency's Planck spacecraft has resolved some conundrums raised by earlier cosmology studies — but has made the riddle of dark matter more obscure. The Planck team did not yet address a controversy over the gravitational waves from the Big Bang announced in March, but plans to do so in an upcoming study.

Planck offers another glimpse of the early universe

From Physics World, Dec. 4, 2014

Results of four years of observations made by the Planck space telescope provide the most precise confirmation so far of the Standard Model of cosmology, and also place new constraints on the properties of potential dark-matter candidates. That is the conclusion of astronomers working on the €700m mission of the European Space Agency (ESA). Planck studies the intensity and the polarization of the cosmic microwave background (CMB), which is the thermal remnant of the Big Bang. These latest results will no doubt frustrate cosmologists, because Planck has so far failed to shed much light on some of the biggest mysteries of physics, including what constitutes the dark matter and dark energy that appears to dominate the universe.

Director's Corner

Toward a strong, international neutrino collaboration

Fermilab Director
Nigel Lockyer

Fermilab has always been an international laboratory. With the proposed Long-Baseline Neutrino Facility based here at Fermilab, we're about to enter a bold new era of global cooperation.

This Friday, Dec. 12, Fermilab will host the second of two open meetings about LBNF. These meetings are a big step toward forming a strong collaboration with partners across the globe, with the goal of building the best neutrino experiment of its kind in the world.

Last Friday, the first of these meetings took place at CERN. We introduced CERN's Director of Research Sergio Bertolucci as the interim chair of the International Institutional Board of the new collaboration, and we explained the organizational structure that we plan to put in place, with input and participation from international funding agencies. Rob Roser walked us through the current draft of the letter of intent for the experiment. Meeting participants discussed how to optimize the design of the experiment and started to discuss the scientific strategy. Many aspects of the experiment are still under discussion, and we are actively seeking input from all interested scientists. The goal is to finalize the letter of intent by Dec. 21 and submit it for review by the Fermilab Physics Advisory Committee, which will meet in January.

This Friday it's our turn to host the second meeting, which has an agenda identical to the first one. It will be held in One West from 10 a.m. to 3 p.m. All interested scientists, from graduate students to engineers to principal investigators, are encouraged to attend. Please register for the meeting so that we know approximately how many people to expect.

The meeting will be a chance to voice your questions and ideas. There will be a panel discussion with an extended Q&A. An agenda with call-in information can be found online.

The next major event in forming a new collaboration for long-baseline neutrino physics will be the PAC meeting on Jan. 15 and 16 at Fermilab. Sergio Bertolucci will present the letter of intent to the PAC on behalf of the nascent collaboration.

Deadlines approaching for Fermilab internship programs

Students come from all over the world to participate in Fermilab internship programs. The laboratory offers a variety of programs for high school students, secondary school teachers, undergraduates and graduate students.

Application deadlines for these programs are approaching quickly. Applications are currently open for our teacher, undergraduate and graduate programs can be found on the internship program page.

Interns have the opportunity to work on lab projects that support particle physics in numerous areas, such as applied physics, engineering and computing. They work with Fermilab scientists or engineers on current research methods and study particle physics research problems.

Please contact Tanja Waltrip at x3929 with questions.
