Special Announcement

Muon g-2 ring magnet expected to arrive on July 26

The arrival of the Muon g-2 electromagnet at Fermilab is expected on Friday, July 26. Fermilab employees, users and neighbors are invited to watch as Emmert International, the company responsible for the magnet's relocation from Brookhaven National Laboratory near Long Island, NY, slowly transports the giant, 50-foot-diameter magnet across Fermilab grounds.

A public event to mark the move begins at 5:30 p.m. on July 26 in Wilson Hall. The magnet is expected to pass near Wilson Hall at 6:30 p.m. Viewing areas will be set up in front of Wilson Hall. A group photo with the ring and all people present will be taken around 7 p.m.

More information on this final leg of the magnet's long journey will be available next week.

Future LHC super-magnets pass muster

In the past four years, scientists at the Large Hadron Collider have accomplished unprecedented feats of physics, all with their particle accelerator working at half its design capacity.

The future is looking even brighter, literally.

Last week the US LHC Accelerator Research Program, or LARP, successfully tested a new type of magnet required to boost the power of the LHC—or the luminosity of its particle beams—by a factor of 10.

LARP is a collaboration among the U.S. Department of Energy's Brookhaven, Fermi, Lawrence Berkeley and SLAC national laboratories, working in partnership with CERN.

The improved magnets are one of the most critical components in a series of LHC upgrades that will be implemented over the next 10 years. In the accelerator, magnets squeeze and focus beams of charged particles, directing them to a point of high-energy collision inside a detector. The new magnets, along with other upgrades, will allow the LHC to collect a larger amount of data at higher energies, making it possible to search for more massive, potentially hidden particles than ever before.

Lucio Rossi, leader of the high-luminosity project at CERN, says the improved LHC could illuminate unexplored corners of physics.

If you enter a dark room with only a candle, the room will be dim, and the candle will soon burn out, he says. But if you have a high-powered flashlight, not only can you see more of the room, but you also have enough time to get a good look around.

"Thanks to this magnet, we will have more collisions, more statistics and more rare events," Rossi says. "If there is physics beyond the Standard Model, these magnets will shed light on it."

Muon catcher in NOvA cavern

The first piece of the NOvA near detector is now installed in the underground detector hall. The picture shows the very downstream end of the muon neutrino detection unit, called a muon catcher. The unit consists of 10 layers of 4-inch-thick heavy steel plates sandwiched by two layers of PVC plastic calorimetry modules. PPD engineers and technicians are constructing and installing the detector unit. It will take two more weeks to finish installation of the whole muon catcher unit. Photo: Cindy Arnold

Why it costs $3 million to ship this magnet up the Mississippi

From Slate, July 15, 2013

If you happened to be standing on the side of Long Island's William Floyd Parkway in the wee hours of June 24, you would have seen a UFO drive by.

Psych! Actually, it was a 50-foot-wide magnet for a particle accelerator, and it's way harder to move than a UFO. Stuffed with superconducting coils, the ring can't twist or bend by more than 2 millimeters. That's not really an issue when it's quietly collecting subatomic particles at a physics laboratory, but it's a big deal now that the magnet is moving from Brookhaven National Laboratory in Upton, N.Y., to Fermilab outside Chicago. The ring's jaunt on the William Floyd was just part one of an epic 3,200 mile voyage, most of which will take place by barge.

From the Accelerator Physics Center

Farewell, Mike Church

Vladimir Shiltsev

Vladimir Shiltsev, director of the Accelerator Physics Center, wrote this column.

The best legacy a scientist can hope to leave behind is based on fond memories, scientific papers and successful projects. The legacy of Mike Church, who served as the deputy head of the Accelerator Physics Center and retired a few weeks ago as the head of the ASTA Operations Department in the Accelerator Division, includes all of that.

I had the distinct pleasure to know Mike and work side-by-side with him for about a decade and a half. Mike was one of the builders of the Antiproton Source at Fermilab and for quite a while led the Antiproton Source Department. In the late 1990s he switched to the Tevatron Department, which he led through the demanding times of the last fixed-target run and the preparations for the startup of the Tevatron Collider Run II.

The Tevatron needed a great number of upgrades to be able to work at 10 percent higher energy, six times the number of bunches and many times higher total beam intensities and luminosities. The startup of Run II in the early 2000s was slow and difficult, and Mike was asked to take the position of the deputy head of the Beams Division (now the Accelerator Division) and was put in charge of Run II. It required great efforts of all the departments in the division and the laboratory as a whole to achieve stellar performance from the collider. The team effort paid off and the luminosity kept increasing.

In 2006, the laboratory began the process of preparing its shift toward a new era of post-Tevatron research. As a part of this strategy, the laboratory established the Accelerator Physics Center. I was appointed to lead the APC, and I was lucky to get Mike on board as my deputy head. He played a key role in setting up the new organization and making it fully functional. Mike's attention focused on the development of the experimental advanced accelerator R&D program, first at the AZero photoinjector and then at our new, world-leading Advanced Superconducting Test Accelerator. As head of the ASTA Operations Department, which is part of the Accelerator Division, Mike and his team achieved a major milestone just a few days before his retirement: They produced the first electron beam with the ASTA RF gun on June 20.

Mike's career at Fermilab is unique in that he made profound contributions to the accelerators of three different types of particles—antiprotons, protons and electrons. And what about his scientific paper trail? In my opinion, one of the most impressive seminal papers on the physics and technology of antiproton production and accumulation was written by Mike Church and John Marriner, published in the Annual Reviews of Nuclear and Particle Science.

Mike Church

I'd like to thank Mike for his great contributions to the development and successes of Fermilab's accelerator complex and the great memories I have of working with him. I wish him all the best in his retirement.

Safety Update

ESH&Q weekly report, July 16

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

An employee was stung by a wasp while maintaining equipment. He received first-aid treatment.

While loading a box onto a truck, a subcontractor pinched his finger between the load and the truck bed, avulsing the end of his finger. This is a recordable injury.

An employee received a superficial laceration when the wrench he was using slipped off the bolt and struck the edge of a wall-mounted support. He received first-aid treatment.

An employee reported pain in his left hip and down his leg from the previous day's work.
