Muon g-2 experiment earns CD-1 approval

2013 was a big year for the Muon g-2 experiment.

Over the summer, the 52-foot-wide electromagnet that forms the core of the experiment was transported from New York to Illinois in a flurry of publicity. Construction began on the building that will house that device and should be completed in the next couple of months.

And in December, the Department of Energy granted Critical Decision 1 approval to the experiment, marking a major milestone and charting the path forward.

Chris Polly, project manager for Muon g-2, said this approval process was the first time that DOE officials have reviewed the entire scope of the experiment, from the design to the cost to the timeline. In order to get to this stage, the collaboration developed a 500-page report, designing and costing every element of the project and then laying those elements out in a schedule consisting of 1,500 activities spanning four years.

"It was an incredible amount of work that required everyone on the collaboration to really focus, thoroughly think through the whole experiment and document it all for the reviewers," Polly said.

The reviewers were pleased with the work and only had a few recommendations. Most notably, the committee suggested that the experiment team work with the DOE to develop an accelerated schedule.

The review took place in September, and the intervening months were spent working out the timeline and funding profile. The work that had already been done to transport the electromagnet and begin construction of the MC-1 Building helped convince the reviewers that the team could keep to such a schedule.

"CD-1 approval is a very important milestone for the experiment, and we appreciate all the strong support that we received from DOE and the laboratory management in getting us to this point," said Lee Roberts, co-spokesperson for the experiment.

The Muon g-2 collaboration received more good news this month as well: The omnibus budget bill signed into law on Jan. 17 includes funding to continue the design and begin construction of the experiment. (That funding is not explicitly spelled out in the bill but is covered.)

2014 will be another big year with the reassembly of the storage ring in its new home, the development of detectors for the experiment and the start of construction for the muon source. And this summer the Muon g-2 team will undergo the next step in the approval process, an extensive CD-2 review.

Dark Energy Survey: one star sets, others rise

The first season of the Dark Energy Survey is now drawing to a close. For another few weeks, collaborators will continue to watch the sky from the summery southern hemisphere. After that, others in the astronomy community will take the reins of the Dark Energy Camera until September. Read more and view the video. Video: Dark Energy Survey

Feds support underground neutrino experiment

From Black Hills Pioneer, Jan. 23, 2014

LEAD — The international high-energy physics community has a lot to be happy about in 2014 so far. Not only did the government's recent passage of the $1.1 billion OMNIBUS Spending Bill include $15 million for the Sanford Lab, which amounts to full funding for the lab this fiscal year, it also included $26 million for the Long Baseline Neutrino Experiment (LBNE), a U.S. Department of Energy-sponsored (DOE) project whose importance to the global physics community cannot be overstated.

Eight most powerful technology implementations

From SiliconIndia, Jan. 21, 2014

Bangalore: The implementation of technology is mirrored very brightly in every aspect of life. The onset of twenty first century witnessed technology revolution with the invention of diesel engine, supercomputer and robots. Researches in the field of energy production and space exploration and other high end technology spheres demanded the need for massive machines with high potential, competence and computational capability. The demand has lead to some of the most powerful technological implementations in the universe. Read on to know 8 of them as compiled by Listverse.

#8 Camera
The world's most powerful camera is titled as Dark Energy Camera and it is used by scientists who study speedy expansion of the universe. Built at Fermilab in Illinois the massive camera is 70 times more powerful than a phone camera. It is handy and can click photographs of masses 8 billion light-years away from earth. The camera constitutes of 5 lenses each of 570-megapixel costing $1.6 million each.

Ready for a cool future

David Harding

David Harding, acting head of the Technical Division, wrote this column.

This month the Technical Division celebrated the successful conclusion of a critical, multiyear upgrade to its helium liquefaction system in Industrial Building 1.

Liquid helium is essential to the testing and operation of all our superconducting devices, including both magnets and RF cavities. For decades, our liquefaction system was limited to providing about 225 liters of liquid helium per hour. Thanks to our successful upgrades, the system's capacity now is 350 liters per hour, an increase of more than 50 percent and consistent with the design capacity of the system.

Back in 2008, Ruben Carcagno and his team in the Test and Instrumentation Department laid out a plan to increase our liquefaction capacity to meet the rapidly increasing demand for liquid helium in IB1. How fast we can make liquid helium limits how many magnet and cavity tests we can run each week.

Many different parts of the liquefaction system needed to be upgraded or modified, and the work needed to be done with little disruption to our busy test program. Ruben and his team developed a plan to stage the work in blocks that could be accomplished during our annual, month-long maintenance period for the refrigeration system. Roger Rabehl from the T&I Department was the lead engineer for this project, and over the course of five years, the team patiently prepared for each opportunity and aggressively took advantage of each one to accomplish the task.

In December, during the holiday period, engineers and technicians ran the two final tests that showed we now can produce 350 liters per hour in a sustained run.

Liquid helium cools the magnets and cavities that we test to below minus 450 degrees Fahrenheit, only a few degrees above absolute zero. This allows us to operate devices in superconducting mode. When we cool a device, liquid helium warms up and starts to boil, turning into gas. Our system captures the gas, cools it with a special refrigerator to condense it again and reuses the liquid for more cooling.

One of the main tests we run involves superconducting magnets. We test them by increasing the current running through it until the magnet stops being superconducting and quenches. That point is the magnet's performance limit. Much of our design work focuses on increasing this limit so that we can build magnets with stronger magnetic fields. Years ago we realized that the testing of stronger and bigger magnets such as the quadrupole magnets for the LHC high-luminosity upgrade would require more liquid helium.

In recent years we have also started testing superconducting RF cavities for high-power particle accelerators. Since much of our R&D is aimed at improving the fabrication and processing of the cavities, we need to cool and test many cavities. Future projects will require the construction of many cavities and hence increase the demand for cooling capacity.

I congratulate the T&I Department and all the people across the Technical Division and the entire laboratory who were involved in this project. This is an important step to support Fermilab's future projects.

Congressman Randy Hultgren and staffers visit Fermilab

Congressman Randy Hultgren and staff members in his district and Washington, D.C., visited Fermilab on Thursday, Jan. 23. The group met with Director Nigel Lockyer, and then the staff members toured the IARC and Technical Division areas, saw the Muon g-2 electromagnet and went underground to see the MINOS, MINERvA and NOvA neutrino experiments.

Safety Update

ESH&Q weekly report, Jan. 28

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

A scientist emeritus tripped and fell over a cable, striking his forehead against the concrete floor, causing a laceration. He was transported to a hospital, where he received five stitches.
