Japanese earthquake jolts Tevatron, emotions

This screen image from the Tevatron main control room shows how the earthquake in Japan March 11 affects superconducting quadrupole magnets in the accelerator tunnel.

Editor’s note: Fermilab stands in solidarity with Japan. We have very strong collaborations with Japanese scientists and institutions, particularly at the laboratory KEK and at universities throughout the country. Our thoughts are with our Japanese colleagues, friends and their families in the aftermath of the tragedies that have taken place. Read more in this message from Director Pier Oddone.

When the 8.9-magnitude earthquake struck Japan last week, Fermilab felt the jolt emotionally and physically.

Accelerator operators in the main control room of the Tevatron saw the heart-rate-monitor-style tracking system for the more than 1,000 superconducting magnets go into cardiac arrest. This signaled the forward and backward pitch and side-to-side roll of the 4- ton, 20-foot-long magnets buried underground.

And that meant somewhere, something very bad had happened.

The monitor readings came from sensors called tiltmeters on underground magnets that steer particles around the four-mile Tevatron ring. They record vibrations too tiny for people at the laboratory to feel, including seismic waves from earthquakes thousands of miles away. The last time the magnets rocked like that was in 2010 when a 7-magnitude quake struck Haiti. The Tevatron also recorded a 2007 quake in Mexico, a 2006 quake in New Zealand, and earthquakes that triggered deadly tsunamis in Sumatra in 2005 and Indonesia in 2004. In all, the Tevatron has felt disaster more than 20 times.

A December 2010 symmetry magazine article explains how physicists first noticed the Tevatron’s super sensitivity, and how they work to make sure it doesn’t interrupt the laboratory’s multi-million-dollar research efforts.

For accelerator operators, learning that the computer sqiggles signaled a quake in Japan was an emotional blow. Fermilab has a long and fruitful history of working with Japanese physicists and institutions. Japanese scientists have been involved with Fermilab from about the beginning of the experimental program in the early 1970s and became key members of the Tevatron’s CDF collaboration in the early 1980s. Many Fermilab scientists, engineers and technicians have friends in Japan, from Japan or have worked at its high-energy physics laboratory, KEK, or JPARC, the high-energy accelerator complex.

In 2010, the most recent data available, Fermilab had 80 visiting researchers from Japanese institutions spread throughout the country, including the areas hardest hit by the earthquake and tsunami. Those scientists are valuable members of several experiments, particularly the CDF collaboration and the accelerator research program. In all likelihood, the Japanese contribute even more to Fermilab’s research program because the also work at the laboratory as users from non-Japanese institutions, but a statistic on the number of those users is unavailable.

Special Announcement

Caregiver Support Group meets at noon today

Fermilab’s Caregiver Support & Resource Group will meet from noon-1 p.m. today in the Small Dining Room of Wilson Hall. All Fermilab staff are invited. If you have questions about how to better cope with caring for your elderly, sick or disabled loved ones, or just need to talk, please join. Ginny Stack, MS, LCPC of Fermilab’s Employee Assistance Program will facilitate this group.



Roberta Forester, a Fermilab employee who retired in 1992, died on March 3. Forester spent 20 years at Fermilab working in several areas, including the Bubble Chamber and the Users’ Office. She is survived by her husband, Paul Forester Sr., a former Maintenance Department employee, and her son, Paul Forester II, who currently works in the AD Cryogenics Department. Visitation will take place from 12:30-2:30 p.m. on Sunday, March 20, at The Larson Nelson Funeral Home, 410 E. Countryside Parkway in Yorkville.

Physicists take stock of quake damage

From Physics World, March 14, 2011

Physicists in Japan are assessing the state of the country's research facilities in the aftermath of Friday's major earthquake and tsunami. The 8.9 magnitude (on the Richter scale) earthquake, with an epicentre around 130 km off the eastern coast of Japan, has wrought untold devastation on the country's eastern coastline. As the clean-up begins, scientists are now beginning to evaluate how much damage has been caused to the country's research infrastructure and facilities.

Fermilab’s 40-year campaign to measure the universe

Craig Hogan

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

In 1990, a handful of Fermilab scientists joined a small consortium of universities to start the world’s first large-scale, precision digital survey of the universe, the Sloan Digital Sky Survey. SDSS went on to wild success and became the most influential observatory of the past decade. Its results received more citations than the Hubble Space Telescope and played a key role in the transformation of cosmology into a precision science.

At Fermilab, SDSS led to an ambitious successor called the Dark Energy Survey. Its name comes from its science mission: To examine the effects of dark energy, the mysterious new physics that accelerates the universe. It will measure light over a swathe of the universe that extends deeper into time and space than what SDSS was able to study. For the new survey, Fermilab has built the ultra-sensitive, 570-megapixel Dark Energy Camera. This summer it will be installed on the Blanco telescope in Chile, where it will take data for the next five years.

But DES is not the end of our campaign to chart the behavior of the universe on the largest scales with pinpoint precision. Fermilab has recently joined the Large Synoptic Survey Telescope project, which will build a new dedicated telescope to undertake a still more ambitious survey. With a larger mirror, larger field of view, faster exposure time and more observing time, LSST will generate hundreds of times more data than DES.

LSST will create a comprehensive map of the evolution of the universe in space and time, taking images of billions of galaxies. It will explore changes in time by taking multiple exposures, creating a deep, wide digital movie of the entire sky. The main LSST survey is currently planned to run from 2020 to 2030. The plans and design are quite definite; indeed, the main mirrors are already being polished.

Fermilab is joining a powerful team of institutions to make LSST happen. It’s likely that we’ll partner with the National Center for Supercomputing Applications on the challenging data management, data access and database for LSST, in much the same way that we managed the data for SDSS. We will likely team up with SLAC and Brookhaven national laboratories on the development and construction of critical camera components, building on our experience with the Dark Energy Camera.

The sequence and timing of these surveys is perfect. It almost looks as if we started planning this whole campaign 20 years ago, and we now can look forward to another 20 years of exciting data and promising research.

Safety Update

ES&H weekly report, March 15

This week's safety report, compiled by the Fermilab ES&H section, lists two recordable incidents. A piece of debris became stuck in an employee's eye while he was using a sander. A subcontracter slipped on black ice and struck her head. She was treated at a hospital.
