Puzzling together Fermilab's ASTA beam dump

At the back of the facility housing Fermilab's Advanced Superconducting Test Accelerator is an elaborately constructed cube of steel and concrete, meticulously pieced together in Tetris fashion using many pieces gleaned from laboratory grounds.

The recycled-steel and -concrete cube will serve as the high-energy beam dump for the future ASTA electron beam. The beam dump stops the particle beam after it has passed through the accelerator and the test beamlines. Last December, Fermilab completed the construction of the dump and installed the beam absorbers at its core. Its completion was the realization of a year of design and engineering work, led by Curtis Baffes from AD's mechanical support department.

"It was fun putting it together," Baffes said. "I tried to puzzle together the re-used steel as well as I could, making sure that the blocks, which varied widely in size and shape, would end up fitting tightly."

At the heart of the two-story-high dump are two beam absorbers, each about the size and shape of a lateral filing cabinet. Nestled deep inside the dump, the absorbers are surrounded by steel plates, which in turn are surrounded by concrete blocks. Together, they stop the beam, contain its energy and shield the outside world from radiation.

DOE scraps plans for neutrino experiment in mine

From Science, March 22, 2012

The U.S. Department of Energy (DOE) is putting the brakes on the development of a gigantic experiment seen as the flagship project for the next decade at the country's sole particle physics laboratory.

At a projected $1.5 billion, the Long-Baseline Neutrino Experiment (LBNE) at the Fermi National Accelerator Laboratory (Fermilab) in Batavia, Illinois, is not affordable, says William Brinkman, director of DOE's Office of Science. So this week he asked physicists to come up with a cheaper way to do the same science.

The current plan for LBNE is to build a gigantic particle detector in the abandoned Homestake gold mine in South Dakota. The detector would contain tens of thousands of tons of frigid liquid argon and would snare elusive subatomic particles called neutrinos fired through Earth from Fermilab 1300 kilometers away.

Dance like a neutrino: Quantum scheme to simulate neutrino oscillations

March 21, 2012

The behaviour of some of the most elusive particles in the known universe can be simulated using three atoms in a lab, researchers at the Centre for Quantum Technologies (CQT) at the National University of Singapore have found.

Principal Investigator Dimitris G. Angelakis and his group members Changsuk Noh and Blas Rodriguez-Lara have devised a scheme that uses the quantum states of three charged ions to simulate the 'oscillations' of neutrinos. The proposal is published in the March issue of New Journal of Physics.

Neutrinos are pesky things to study: they barely interact with matter and have a very tiny mass. Experiments to study them typically use vast detectors to capture neutrinos produced in the Sun or in particle accelerators.

Quality Assurance

Getting ready for April engineering assessments

Photo: Tom King

Beginning in April, the Office of Quality and Best Practices (OQBP) will perform quality assessments to verify implementation of the Engineering Manual throughout Fermilab. DOE personnel will participate in two of these assessments. To determine when OQBP will be assessing your organization, check the 2012 QA Assessment schedule.

The Fermilab Engineering Manual, which contains the process for properly executing and documenting engineering projects at Fermilab, was announced in July of 2010, followed by an Engineering Manual roll out meeting. Use of the Engineering Manual at Fermilab is a requirement, not an option.

Recently Fermilab physicist Peter Garbincius, in conjunction with the Engineering Policy Committee, conducted a survey of all divisions, sections, centers and projects to determine their awareness and use of the Engineering Manual. Garbincius is the owner of the Contractor Assurance System Engineering Management System and the Engineering Manual.

If you are involved in design or engineering within your organization, you should review the contents of the Engineering Manual, the appendices, the risk assessment worksheet and the slides from the roll out meeting, to ensure you are familiar with and following the engineering practices required by the director's eighth policy.

For more information on the Engineering Manual or on what to expect during the QA engineering assessment, contact your department head, division/section/center Quality Assurance representative or a Quality Assurance engineer from OQBP.
