Assistant Director Jeffrey Appel retires this week

Jeffrey Appel

After serving Fermilab for nearly 37 years as a physicist and administrator, Jeffrey Appel is retiring as Assistant Director for the Program Planning Office.

His last day in the directorate is July 13, but it won't be his last day at the laboratory.

"I'll be back to help finalize the CDF papers," he said. "It's just for the pleasure of working with the physics results."

The pleasure has spanned research in accelerators, detectors and computing. As a scientist, Appel was a collaborator on the E-288 experiment, which made the discovery of the bottom quark in 1977. He later investigated heavy quark physics at the Tagged Photon Laboratory, as well as at the BTeV and CDF experiments. At the TPL, he served as spokesperson of E-769 and co-spokesperson of E-791.

"One of the pleasures of being at Fermilab is being able to participate in so many different things," Appel said.

The variety of his experiences, both scientific and non-technical, made him an excellent fit for the Program Planning Office, where he has coordinated the research of the many experiments and accelerator studies according to the laboratory's priorities.

"He has deep and broad knowledge of the science, the experiments, the users and the accelerators, which he uses to help us mount the optimal program here at the lab," said Associate Director for Particle Physics Greg Bock.

In addition to researching particle physics, Appel has expanded opportunities for students, teachers and the public to better understand science.

Soon after he started at the laboratory, Appel initiated the Bicentennial Lecture Series, a Friday night series of science and humanities talks. They attracted speakers such as Jane Goodall and Carl Sagan. For 10 years, Appel served as head of the Auditorium Committee. He also co-directed the first Hadron Collider Physics Summer School, initiated the first summer teacher-hiring program at Fermilab and was a member of the Board of Trustees for Fermilab Friends of Science Education.

Appel has also held several leadership roles at Fermilab, including head of the former Computing Department and of the former Physics Section. He served as project manager for the Central Computing Upgrade Project, a $25 million endeavor that led to the construction and operation of the Feynman Computing Center.

"I've worried about the bureaucracy, the science, the field and the laboratory and tried to do things that are useful wherever I could," he said.

"Jeff will be sorely missed," said Fermilab Director Pier Oddone. "He is imperturbable under the many conflicting demands of experimenters and has optimized our program over many years."

Appel retires from Fermilab as an American Physical Society Fellow with more than 250 papers to his name. He plans to remain involved in science after retiring, maintaining a connection with the laboratory.

"Working here is working with some wonderful people," Appel said. "That isn't just a platitude."

Our experimental physics program focuses on understanding the origin of electroweak symmetry breaking, searches for new physics and precision tests of the Standard Model. We are also involved in precision measurements at low energies, which provide information complementary to that obtained at the highest-energy colliders. Our theory group works on understanding the origin of electroweak symmetry breaking, numerical simulations of quantum chromodynamics, cosmology, and the application of mathematics to quantum field theory.

We have a very broad and diverse experimental/theoretical particle physics program. We have an excellent Electronics Design Facility, a state-of-the-art Scientific Instruments Facility and an extensive network of computational facilities that support our research activities. We have helped design and build many particle physics detectors all over the world. Our Geneva Physics program allows many of our undergraduate students to take classes at the University of Geneva and participate in cutting-edge research at CERN. We are thus able to attract some of the best undergraduate and graduate students to BU.

From the Technical Division

A new generation of magnets for accelerators, MRIs

Giorgio Apollinari, head of the Technical Division, wrote this column.

Giorgio Apollinari

In March 2011, I wrote about the collaboration we began with CERN for the development of high-field niobium-tin (Nb3Sn) dipole magnets. Today, after less than 15 months, I am happy to report on the success the 11-Tesla project has achieved in this short period, and the potential of this technology beyond particle physics.

To my knowledge, the project set a record for turning an idea for a collared Nb3Sn superconducting magnet into a working, accelerator-quality magnet with an acceptable aperture and strong magnetic field in less than 20 months. Exceeding the 10-Tesla barrier with the relatively new niobium-tin technology instead of the more common but less powerful niobium-titanium technology clearly shows that, in my opinion, the Nb3Sn technology is ready for applications in accelerators and beyond.

The 11-Tesla project originated from a proposal made by CERN’s Lucio Rossi in September 2010. To increase the number of collisions produced by the Large Hadron Collider, he suggested replacing a few 8-Tesla dipole magnets in the LHC tunnel with shorter, stronger, 11-Tesla magnets in order to create enough space to install additional collimators. The only way to achieve this goal is to use the relatively new Nb3Sn technology.

Rossi’s proposal aligned well with the goals of Fermilab’s High-Field Magnet R&D program, which aims to develop collared magnets with fields in excess of 10 Tesla for use in future machines such as the Muon Collider. The two laboratories quickly established a collaborative effort.

The technical team started its work in late 2010. Fermilab and CERN manufactured coils and other parts for the first 2-meter-long, collared Nb3Sn dipole magnet, which was completed this spring. The testing of this model in our facilities started a few weeks ago. Although it is the first magnet that we've made for this specific program, it almost could be installed in the LHC as is. Further tests will determine the detailed magnetic field quality and transient field performances of this magnet.

In the last couple of weeks, we achieved an electrical current of up to 11.2 kiloamps, only 5 percent below the goal of 11.8 kA for the 14-TeV LHC. According to our latest measurements, the current creates magnetic fields of approximately 10.4 Tesla. The test, performed at a temperature of 1.9 Kelvin in the Fermilab Vertical Magnet Test Facility, continues as we aim to understand the ultimate field that this magnet can achieve.

The great news is that the Nb3Sn technology will have applications beyond particle physics as well. I expect that in a few decades, thanks to our efforts today, hospitals will rely on Nb3Sn-equipped MRI systems, which will provide more detailed images due to the higher magnetic fields achieved by these magnets, leading to improved medical diagnoses. The Illinois Accelerator Research Center, under construction across the street from the Technical Division, will act as the proper bridge to bring this exciting particle accelerator technology to society.

Safety Update

ES&H weekly report, July 10

This week's safety report, compiled by the Fermilab ES&H section, contains five incidents.

Two subcontract employees had ticks embedded in their skin. They removed the ticks and reported to the Medical Department as a precaution.

An employee suffered a minor laceration when he struck his arm against a fixed object. He received first-aid treatment.

Another employee was stung by a wasp. The employee received first aid treatment.

Another employee was struck on the lower left lip when the lifting strap he was pulling on came loose. He received first-aid treatment.

A contractor employee in AD had been working in the Main Injector enclosure for a period of 8 weeks without wearing a personnel dosimetry badge. He had been wearing a pocket dosimeter and was tabulating his dose. AD is currently investigating to determine the errors and organizational weaknesses that led to this unwanted outcome.

Dark matter filament found, scientists say

From the Los Angeles Times, July 4, 2012

The mysterious stuff called dark matter is thought to act as the spider silk for the cosmic web of the universe. But although it makes up most of the matter in the universe, scientists have been able to find only clumps of it in the web's galaxy-filled "nodes," not along the gossamer threads that are thought to help give the universe its structure.

Now, after much searching and with a little luck, an international team of astrophysicists has discovered a dark matter filament connecting two clusters of galaxies about 2.7 billion light-years away.
