CMS Result of the Month

Drinking data from a fire hose

In a classic episode of I Love Lucy, Ethel and Lucy have to deal with candy being delivered ever more quickly. CMS is encountering the same situation with beam delivered by the LHC, with rather better results.

With 2 1/2 months of running CMS under our belts, the experiment's mid-range goals have evolved. Initially we were happy to record any interactions at a collision energy of 7 trillion electron volts. However, it’s important to recall that the beam energy is only one of the important parameters in a particle collider. A second critical parameter is the brightness of the beams, and, in the first few weeks of running, the brightness of the beams was tiny. Under these circumstances, the number of collisions per second was quite modest, and we could record every collision that occurred.

However, the beam brightness has steadily increased over the past two and a half months. It currently takes a minute to see as many collisions as we used to see in a day. Very soon, the same number of collisions will take seconds. Those of us of a certain age might remember the old I Love Lucy episode in which she and Ethel wrap candy. It starts out easily, but the rate quickly increases until they can no longer handle it and chaos ensues. This is essentially the situation in which the CMS detector collaborators find themselves.

Of course, this was anticipated. Today’s thousands of collisions per second are a far cry from the designed 800,000,000 collisions per second. To cope with the deluge, CMS designed an extensive trigger system. As the torrent of collisions occurs in the center of the detector, carefully designed electronics inspect them all and select those that are most likely to include a discovery. The LHC is now delivering enough beam that we must utilize the trigger system to record only a portion of the collisions.

This is a unique time in the lifetime of an experiment. About every week, the amount of beam delivered by the LHC doubles. With our trigger electronics doing their job, we look forward to seeing our data set grow in leaps and bounds.

-- Don Lincoln

The amount of beam delivered has increased enormously. In the month and a half (45 days) since beginning operations, the amount of beam delivered is more than 10,000 times what we saw on the first day.

Sloan spots one hundred thousand black hole behemoths

From Discovery News, June 9, 2010

The Sloan Digital Sky Survey (SDSS) has mapped the sky and created a database of millions of objects for astronomers to study. This, all with a 2.5-meter telescope in New Mexico. The latest data release catalogs 105,783 quasars, or the active centers of distant galaxies with supermassive black holes.

At the time that SDSS began, only 6,000 quasars were known. Now, this huge database gives the positions, colors, and distances of over 100,000 quasars. The most distant of these is over 12.5 billion light years away, meaning that its light reaches us from when the universe was just over a billion years old.

WIDE ANGLE: Black Holes, Big and Small

This kind of project has been a major shift away from small teams studying individual objects with their telescope time. These data are taken and analyzed and made available to the entire astronomical community, such that a researcher or student at any institution can go in with an idea and use these massive catalogs to do their science.

Work-in-progress: IB-3 addition shaping up

Workers have set in place the steel shell for the Industrial Building 3 addition.

When walking around the construction site of the Industrial Building 3 Addition, you need only a little imagination to visualize halls, offices, an elevator and skylights. The steel shell for the addition is now in place, marking the future location of Fermilab's new materials laboratory space.

The American Recovery and Reinvestment Act is providing $4.9 million for the project, including approximately $3 million to cover initial construction costs. The remaining budget will fund furnishings and several building upgrades, as well as construction management and a budgeted reserve to account for unplanned costs.

A. J. Maggio Co., a firm based in Mt. Prospect, Ill., received the contract to construct the addition. The project has sustained seven full-time employees, an increasingly unusual opportunity during the difficult economic times.

"Fermilab has been easy to work with and very accommodating," said Ken Kleiner, on-site supervisor for A.J. Maggio Co.

The 40-by-192-foot addition will include much-needed space for testing superconducting materials for high-field magnet research and development, and contribute to superconductor radio-frequency research and development.

"Plans for this addition have been on the board since 2003. After several functional changes, it's good to finally start building," said Fermilab Project Manager Russell Alber.

Even after making design changes to accommodate the laboratory's requirements, Fermilab project management and A.J. Maggio Co. have extended the original schedule by only four days. Within a week, eight-inch concrete decking for the second floor will be set. Weather permitting, the building will have a roof by the end of the summer and should be ready for occupancy by the end of December.

"We are very pleased with how the work is proceeding," said Romesh Sood, Fermilab's project director. "When completed, the facility will provide essential and much needed research and development space for the current projects."

Special Announcement

West Wilson Hall parking lot repairs begin Tuesday

Pavement repairs to the Wilson Hall west parking lot will begin Tuesday, June 15. Roads and Grounds staff expect that the work will take two to three days.

The repairs will result in a reduction of parking area, so some employees may need to use the Lederman Science Center lot for overflow parking. Temporary overflow parking signs will guide drivers. Traffic in the west lot may also be delayed at times by flaggers.

Inclement weather could affect the repair schedule next week. Please watch Fermilab Today for further updates.
