From symmetry magazine

LBNE: the inside buzz on a new science project

Illustration: Sandbox Studio

Editor's note: This story appears in the latest issue of symmetry magazine. Read the magazine online.

Planning and designing the $900 million Long Baseline Neutrino Experiment takes more than a village. It takes a hive’s worth of scientists, engineers, technicians, accountants, and other specialists of every stripe.

A single bee colony, that model of industry and organization, may contain upwards of 40,000 bees. Yet so flawlessly choreographed are their interactions and so well does each bee know its business that the whole hive effectively functions as a single organism. While the hundreds of collaborators in a large scientific project may not see themselves as one big organism, in fact they have much in common with the bees. To achieve sweet success, they must all carry out their particular roles in the project, and they must work together in a highly organized and coordinated fashion.

A look behind the scenes of Fermilab’s Long Baseline Neutrino Experiment reveals a colony of scientists, engineers, and project specialists, from across the United States and around the world, abuzz with the work of creating what they hope will become the world’s most advanced neutrino experiment. Each member of the 300-person team for this $900 million undertaking has a specific set of tasks. An intricate system of organization and communication meshes their efforts together to achieve each stage of the project’s development—from initial approval to construction, operation, and scientific discovery.

LBNE will measure fundamental properties of neutrinos to probe questions at the heart of 21st-century particle physics. The “Long Baseline” in Long Baseline Neutrino Experiment refers to the distance a beam of neutrinos traverses from its origin to a detector. Fermilab accelerators will generate the world’s most intense neutrino beam and aim it through the earth to underground detectors at the Homestake Mine in Lead, South Dakota, 800 miles away. Another detector on the Fermilab site, known as the near detector, will characterize the beam as it starts its journey.

In Brief

Fermilab to launch new scientist emeritus policy

Scientists who retire from Fermilab can soon apply to be considered for scientist emeritus, a status of honor granted in recognition of the scientist’s contributions to the laboratory over his or her career.

The new status is a result of the most recent Fermi Research Alliance, LLC Board of Directors meeting. It is reserved for scientists who are retiring from the laboratory. The FRA board will approve all scientist emeritus appointments.

Retired scientists with emeritus status will receive an invitation to continue scientific connections with the laboratory. Scientists with emeritus status will belong to a division or center and may receive Fermilab resources as appropriate.

To initiate the appointment process, scientists must discuss emeritus status with their division or section head, who may then recommend the status to the Directorate. The Directorate may then recommend the appointment to the board, summarizing the candidate’s career accomplishments and major contributions to the laboratory.

Fermilab is working to formalize this process. More details will be publicized as they become available.

Watching the cosmic web unfold

Craig Hogan, head of the Center for Particle Astrophysics, wrote this week’s column.

Craig Hogan

The grandest spectacle in the universe is the structure defined by galaxies on the largest scales. Called the cosmic web, it is an enormous, perhaps even infinite structure, with a transcendent beauty. Dense clusters, each one swarming with thousands of orbiting galaxies, connect with each other over gossamer filaments and delicate sheets of galaxies, stretching across tens to hundreds of millions of light years. Between the sheets loom large, nearly empty voids. Similar clusters, filaments, sheets and voids extend as far as we can see in all directions, and probably far beyond that.

This majestic structure has been created from a nearly uniform expanding gas of matter by the simple force of gravity, the same process that earlier created galaxies. Using powerful computers, scientists can simulate its evolution over billions of years, as the cosmic web emerges from uniform matter: voids expand and galaxies stream, swarm and merge into larger galaxies and clusters. The simulations reproduce the properties of this complex structure very well, using remarkably few assumptions. The detailed evolution over time does depend on some unknown cosmic physics, in particular, the behavior of the dark energy that is accelerating the cosmic expansion.

For a physicist, it is deeply moving, as well as scientifically instructive, to compare the views of the computer simulation with the real cosmic web. Our first glimpses of the cosmic web— the closest clusters, filaments, sheets and voids— started to come into view about 30 years ago, when galaxy redshift surveys started to give us a three-dimensional map of the cosmos. The Sloan Digital Sky Survey, Fermilab’s first foray into large spectroscopic surveys, used a system of optical fibers to collect spectra and make a breathtaking 3D map with about a million galaxies, and hundreds of sheets, filaments and clusters. The real cosmic web, as seen by SDSS, that you can virtually fly through online (or view as part of a tour of the known universe), looks remarkably like the computer-generated universe based on the physics of gravity, dark matter and dark energy.

How to keep lonely exoplanets snug - just add dark matter!

From Space Daily, June 27, 2011

Dark matter is perhaps not the first thing that comes to mind when considering how life can be supported on another planet, but to Dan Hooper and Jason Steffen of the Fermilab Center for Particle Astrophysics, dark matter could be a contributing factor in allowing life to evolve and survive on distant worlds outside of our solar system.

The scientists propose that dark matter particles could sink into a planet's core, and through the annihilation of matter, release enough energy to keep the surface of the planet warm enough for liquid water, even outside the traditional habitable zone.

Dark matter was first postulated in 1933 by Fritz Zwicky, and then again in the 1970s by Vera Rubin to account for evidence of 'missing mass' in the orbital velocities of galaxies in clusters and stars at the edges of galaxies. Dark matter is inferred to exist from its gravitational effects on visible matter and background radiation, but it emits no visible light and does not interact with any other matter except by gravity.

Safety Update

ES&H weekly report, June 28

This week's safety report, compiled by the Fermilab ES&H section, includes no recordable incidents and two injuries requiring first-aid treatment: An employee tripped on carpeted stairs, twisted an ankle and ended up with a broken fibula and displaced bones of the ankle, and an employee bumped the right rear bumper of a parked car with the front bumper of employee’s car.
