CMS detector completes cosmic practice runs

CMS staff take a shift in the Remote Operations Center.

Experimentalists at the CMS detector are using the downtime before the Large Hadron Collider is back up and running to get in some exercise.

Researchers used the detector to record data from more than 355 million cosmic events during four weeks in October and November. This was the longest test run with the magnetic field on.

"Since everything was in place, we could really show the whole detector working together," said Ian Fisk, deputy manager for CMS software and computing. "It's a very complicated system, and what you're looking for is to understand its behavior."

Cosmic rays that constantly pass through the earth activate triggers in the detector's sensors just as particles scattered by a collision would do. By tracing their paths and noting the amount of energy the detector records without the presence of beam, researchers can calibrate the detector and better learn how to read it.

"You look for the same things you would if you had beam," said Dave Mason, a Fermilab postdoc.

But, if you see peaks without the beam operating, you know you need to work on eliminating background interference, Mason said.

Researchers used the test run to find and fix foibles in the detector, said Kaori Maeshima, U.S. CMS operations coordinator working at Fermilab.

"There was nothing really bad, no show-stoppers," she said. "But we learned lots of useful things." They discovered, for example, that ambient light in the collision hall affected one component of the detector. This was fixed.

The run also exercised the LHC Computing Grid, which will process and distribute the vast amount of data that the LHC will collect once at full power. All of CMS's Tier-1 centers, including Fermilab, received the data, along with some Tier 2s and at least one Tier 3.

The CMS collaboration plans to conduct more cosmic runs in the next several months.

Winter serene

AD's Marty Murphy took this photo at the Main Injector (MI50) pond on the evening of Friday, Dec. 26. The thick snow on the ground, plus the day's warm temperatures caused a dense fog.

For a big view of inner Earth, catch a few.Geoneutrinos

From Science News
Jan. 17, 2009

Were the Earth a crystal ball, you might gaze 2,900 kilometers down to its outer core with a telescope. The Earth, though, is frustratingly opaque - to light. Most knowledge of the planet's internal structure comes from studying seismic waves, which give a kind of ultrasound image. Inferences about Earth's internal chemistry rely on the elements found in near-surface rocks, meteorites and the sun.

Recently, geoscientists have developed a new tool for probing the Earth's innards. Borrowing a page from astrophysics, they are using the curious subatomic particles known as neutrinos. Astrophysicists have used neutrino telescopes for decades to study neutrinos originating in the sun and elsewhere in the cosmos. Now earth scientists are taking a neutrino telescope and looking down, to illuminate the Earth's interior by detecting "geoneutrinos" - neutrinos produced within the planet itself.

Director's Corner


Pier Oddone

The new year brings about new resolve. It is customary to make resolutions that promise to bring about improvements in how we live our lives. These resolutions are easy to make and often quite difficult to keep. It is a good thing that the score keeping is pretty sloppy.

In this atmosphere of increased resolve brought by the new year, it is useful to think of all that we want to accomplish at Fermilab in 2009. For us, it is a more serious affair since a lot of planning goes into setting our goals for 2009; they are public and the DOE will surely keep score.

The Tevatron is breaking new records constantly. Maintaining this trajectory through 2009 will support our case for running the Tevatron at least through 2010. The doubling time for collected data is only two years, even after 20 years of running because the machine has improved constantly. The neutrino program with MiniBooNE and MINOS will continue to produce world-class results and set the stage for future neutrino projects at the lab. The LHC will turn on and hopefully will show some spectacular early results. The particle astrophysics program in dark matter, dark energy and ultra-high-energy cosmic rays is again poised for important results.

While the physics program through 2009 will be vital, probably the most important task in front of us is to develop the future projects that will sustain the laboratory and the community through the next decade, after the Tevatron shuts down. NOvA, MINERvA, MicroBooNE, DES and JDEM, larger COUPP and CDMS detectors, the DUSEL Beamline and detector, the mu2e experiment, Project X, the LHC and its upgrades, the ILC R&D and the muon collider R&D constitute a huge agenda for the laboratory. It would tax us even if we were not running a full physics program. These programs will be lean during the next couple of years so they will be in a position to benefit from the staff that will roll off the Tevatron. All of them will involve national and international collaborations since they collectively exceed the capacity of our laboratory.

High on our list is to maintain and even improve our performance in safety. Last year we lowered our injury rates to an unprecedented low level, a rate that is hard to measure with any statistical precision. We must maintain this focus on safety. This achievement is its own reward because it keeps all of us safe.

We also have a large agenda of improvements in the operational side of the house. We will implement the integrated quality assurance system for the lab, make a transition to uniform practices across divisions in engineering and start to move to more coherent IT integrations in support of laboratory functions. This will happen in addition to the myriad small improvements that take place in our everyday operations.

To accomplish all this is a tall order and will require many skills that we must deploy efficiently. And we need a budget! Stay tuned.
