Fermilab accelerator complex starts up after long shutdown

A beam of protons whizzed through the Main Injector for the first time in over a year on July 30, representing a major milestone in the year-long process of overhauling the Fermilab accelerator complex. The upgrade will eventually culminate in an accelerator with double the power it had previously.

"The shutdown has been challenging, and we all look forward to returning to beam operations and providing beam to the experiments," said Dave Capista, an engineering physicist in the Accelerator Division. "It is exciting for us to see the results of our hard work."

The upgraded accelerator complex will push the laboratory's Intensity Frontier program forward, ultimately delivering high-intensity beams efficiently to the many current experiments that use it and to the future Muon g-2 and Mu2e experiments.

Upgrading the complex requires an elaborate choreography of four main pieces: the Linac, the Booster, the Recycler and the Main Injector. Prior to the 2012 shutdown, the Main Injector and Recycler operated mostly independently. The primary change in the new system is the ability to move beam manipulation functions out of the Main Injector and into the Recycler, allowing the two to coordinate operations to deliver more beam in less time, resulting in more powerful beams.

Now that the Main Injector has seen beam, the laboratory will begin gradually ramping up accelerator operations.

With the Main Injector now operational, it can send low-intensity beam to the NuMI target and the Switchyard so experiments such as NOvA and SeaQuest can begin to commission their equipment. Within a few weeks, the Accelerator Division hopes to begin running beam through the Recycler so commissioning can begin there as well.

"Once you have all the equipment functioning and doing its job, then it's a case of sitting down and doing the tuning and understanding how the machine behaves," said Phil Adamson, a scientist in the Main Injector Department. "It'll be a fun period. There are a lot of systems, so there are a lot of things to do. It will take time."

Although the Recycler isn't operational yet, in the coming months the Accelerator Division will begin running beam through it and hope to have the Recycler and Main Injector working together by the end of the year. Ultimately, the Fermilab accelerator will deliver beams of up to 700 kilowatts, instead of the current maximum of 350.

"It's simply about trying to deliver as much as we can to all the customers that we have," said Duane Newhart, deputy department head of the Operations Department. "We have a lot. And we hope to have more."

As the beam is ramped up to greater intensities, the Accelerator Division will monitor how the machines handle it and make adjustments as it goes along.

"When you get to the highest intensities, that's where you find all the edges," Adamson said. "At the lower intensities everything works fairly easily, but when you start pushing intensity as high as you can go, all the interesting features start to show up."

Fermilab will celebrate the restart of the accelerator complex in the fall.

Accelerator Update

Accelerator update, Aug. 7, 2013

Main Injector:
FESS worked with contractors to replace surge arrestors at the Kautz Road Substation.

Main Injector experts turned on power supplies, established ramps and established 8-GeV beam in the Main Injector. They subsequently established 120-GeV beam, smoothed the beam orbits during ramp-up and tuned the abort line.

Main Injector experts extracted low-intensity beam to the NuMI beamline. NuMI experts started tuning it up for horn scans.

The future of high-energy physics

From Physics Central Buzz Blog, Aug. 5, 2013

The High Energy Physics (HEP) landscape has changed significantly over the past few years. Fermilab's Tevatron—once the king of particle accelerators—ceased operations two years ago as LHC scientists cranked up the energy at the world's highest-energy particle accelerator. Months later, scientists there announced conclusive evidence that they'd seen an elusive Higgs-like boson for the first time.

Much of HEP research now revolves around the LHC, and young particle physicists face different research priorities, career prospects and opportunities compared to what their older advisers faced years ago.

Consequently, at a recent annual meeting of HEP physicists, organizers polled their peers on where HEP research is headed and what will happen to physics jobs in this field. In particular, they focused on the views of young physicists facing a nebulous funding environment with shifting priorities.

From the Fermi Site Office

The benefits of teamwork

Michael Weis

Michael Weis, DOE Fermi Site Office manager, wrote this column.

Less than two weeks ago, the Muon g-2 storage ring was successfully delivered from Brookhaven National Laboratory near Long Island, NY, to Fermilab, completing a highly publicized and closely watched month-long, 3,200-mile cross-country trip. It's been a very long journey, both literally and figuratively, and took incredible teamwork to relocate the 50-foot-diameter ring. We are proud to have been part of the team that brought the ring to Fermilab.

The Fermi Site Office, along with Fermilab, Brookhaven Lab, the Brookhaven Site Office, the DOE Office of Science program representatives and its Integrated Support Center, worked together as a team to plan and complete the numerous and myriad activities necessary to disassemble and move the storage ring and associated subsystems over land and water. Contract reviews, environmental evaluations, project approvals, and health and safety reviews were just a few of the many steps along the path that FSO completed to support the project and enable the successful move.

The FSO team was instrumental in the review of the transportation subcontract and participated at Brookhaven as part of the relocation team in safety reviews, public relations planning and other logistics, including a review of the entire 3,200-mile route. Additionally, as part of an ad hoc committee, FSO gave recommendations on transportation, construction and operations when it came to clearing or excavation, demolition and decommissioning, air emissions, liquid effluent, hazardous or other regulated waste, radiation exposures or radioactive air emissions, new or modified permits, and public utilities and services.

The FSO team also watched along with many of you as the ring made its way to Fermilab, culminating in one of the most notable celebrations in lab history on July 26.

Delivery of the ring was just an early step in executing the Muon g-2 experiment, which will be more sensitive to virtual or hidden particles and forces than any previous experiment of its kind. The experiment will make use of the Fermilab accelerator complex's intense beam of muons to measure with high precision a quantity known as the muon magnetic moment. If confirmed, the discovery would open a window on subatomic interactions that go beyond the particles and forces described by the Standard Model.

This experiment is one of many that will continue to deliver exciting science at Fermilab. And, like the others, it reinforces the fundamental teamwork required for success of both Fermilab and all of us involved in these important DOE Office of Science activities.

Safety Update

ESH&Q weekly report, Aug. 6

This week's safety report, compiled by the Fermilab ESH&Q section, contains one incident.

A visitor suffered a laceration on his index finger when the wrench he was using slipped. His finger was cut either on the floor grating or on the corner of the unistrut he was adjusting. The laceration required three sutures. This case is recordable.

Science Committee members hear from Secretary of Energy on national labs

From FYI: The AIP Bulletin of Science Policy News, Aug. 6, 2013

Chairwoman Cynthia Lummis (R-WY) and Ranking Member Eric Swalwell (D-CA) of the House Subcommittee on Energy recently sent a letter to Secretary of Energy Ernest Moniz requesting information on Department of Energy (DOE) National Laboratories. Moniz responded on July 10, giving an overview of science and technology priorities which were the subject of a recent hearing.
