NOvA team assembling near-detector blocks at CDF

Fermilab scientists, engineers and technicians working on the NOvA near detector recently began assembling the neutrino detector blocks at the CDF building.

It's a milestone accomplishment, said near-detector Project Manager Ting Miao. The near detector being constructed at Fermilab will be able to pick up on muon neutrinos sent from the NuMI beam, which originates at the laboratory and passes through NOvA's second, far detector in Ash River, Minn. The near detector will also be able to define background noise that will be eliminated while analyzing far-detector data.

"It's an exciting time now for scientists and engineers working on the detector," Miao said.

Each block comprises 24 long, rectangular plastic layers known as modules. The blocks are nearly identical to the ones that make up the 14,000-ton far detector, but are one-twentieth the size and weigh much less. Each module contains rows of hollow tubes that will be filled with liquid scintillator solution and fiber optic cables to detect charged particles resulting from neutrinos interacting in the solution.

Scientists and engineers have spent the past month obtaining safety approvals to operate a giant, 20-foot-long glue machine that spreads adhesive on the module surfaces.

The machine, developed and built by NOvA collaborators at Argonne National Laboratory, handles the fragile modules with care while also applying the fast-drying glue. Spreading glue on a module's surface, transporting it and stacking it on top of other modules takes less than 20 minutes—any longer and the glue will dry out, said Detector Assembly Quality Assurance Manager Xuebing Bu.

A set of steel plates will then apply pressure to the stacked modules to ensure a tight fit.

But handling the modules is not as easy as it sounds, Bu said.

"The plastics are flexible and difficult to move around, and the glue we are using has a short curing time," Bu said. "We need to have the correct equipment to operate efficiently while also meeting safety standards."

Applying pressure to the stacked modules is also a delicate task. The team follows well-defined procedures to avoid the plastic experiencing extra stress from being lifted and moved around, Bu said.

Soon the team will begin transporting the blocks from the CDF building to the MINOS service building and eventually into the NOvA cavern 300 feet underground.

It may take an entire day to drive the blocks to the site without cracking any of the detector layers, Miao said.

"The plastic we're using is well-suited for the experiment, but very fragile," Miao said. "Transporting the blocks will be a big hurdle to cross."

But if all goes smoothly, the NOvA detectors could yield precise neutrino measurements by early next year, Miao said.

"NOvA's level of complexity and sophistication are now comparable to detectors in fixed-target and collider experiments. This detector is built for precision measurements of neutrinos," Miao said. "We are looking forward to the steps that lie ahead."

Solar flares fire off antimatter particles

From Space.com, July 9, 2013

Astronomers have detected exotic antimatter particles flying from the sun during solar flares—a discovery that could help scientists understand this mysterious sibling to matter.

Solar flares were predicted to release some antimatter particles among the deluge of charged particles spat out during these eruptions. But this is the first time researchers have observed antimatter coming from the sun.

Director's Corner

Strategic lab agenda

Jack Anderson

At Fermilab we must effectively and efficiently align scientific research efforts to meet our customers' and collaborators' most critical needs while building capabilities to meet future lab requirements. These demands are complicated by inevitable resource constraints that raise challenges—the most critical being the alignment of plans and budgets to support our future.

To address this challenging environment, we have developed a comprehensive, labwide strategic agenda to help organize internal strategy discussions and priority-setting. The agenda provides a framework for an integrated, five-year plan that supports the three frontiers of particle physics along with the facilities and operational capabilities needed to ensure success.

The new Strategic Fermilab Agenda was developed over a six-month period beginning this fiscal year as part of the annual planning and budget process. It has evolved through critique and scrutiny during management workshops and in review with our primary customers, and it aligns with Fermilab's most critical current and likely future challenges.

Why is the lab agenda important and why should you become familiar with it? First, it provides a relatively straightforward view of the complex landscape that we work in—what we're doing and why we're doing it. Second, it illustrates how we can achieve the lab's high-level, long-term goals. Third, it provides a structure for constructive management debate and decisions as we focus on planning for the future. The plan comes with a caveat: It is not intended to address everything that the lab does but instead focuses on major initiatives that are critical to our future successes.

The agenda provides a clear line of sight from long-term, strategic objectives to the organization's current-year initiative plans. The agenda's initiative plans are in various stages of development and serve as concise actions that focus on critical outcomes and milestones. Although initiative plans are not complete, we have started using the plans as an organizing construct while they are being finalized. The agenda is a tool that will clearly improve and mature with time and discussion.

I encourage you to take a few minutes to familiarize yourself with the lab agenda.

Neutrinos: nature's identity thieves?

The oscillation of neutrinos from one variety to another has long been suspected, but it was confirmed only about 15 years ago. US CMS Education and Outreach Coordinator Don Lincoln explains how we know it occurs and touches on the rich experimental program at several international laboratories designed to understand this complex mystery.

Phase 1 installation of the MicroBooNE experiment at the Liquid-Argon Test Facility is well under way. The intermediate deck has been removed to allow installation in the pit of the cryostat supports and the cryogenic system. The supports consist of shielding blocks and foam saddles. In the picture's lower right corner are the liquid-argon circulating pumps. In the center of the picture is one of the two purifier skids for removing contaminants. Some of the foam-insulated cryogenic pipes are seen lying on the floor of the pit. Electrical work to wire the pumps has also begun.
