Fermilab's Main Control Room

What do you do now that the Tevatron is shut down? This question, spurred by lay curiosity or by ignorance, plagues Fermilab employees and users. But Cindy Joe, an operator in the Main Control Room, has an answer.

"The Tevatron was just one of the many machines we run here," Joe said. "There are a lot of other experiments and a lot of science to be done."

The MCR is responsible for the transmission of the beam to about a half-dozen experiments scattered around the site. New experiments are coming online. Two weeks ago, operators sent beam to the SeaQuest experiment for the first time.

On a map of Fermilab, Dan Johnson, head of Accelerator Operations, traced the old and current paths of the various particle beams on the Fermilab site.

"When the Tevatron was running, we'd use it for experiments that required an accelerated proton beam colliding with an antiproton beam. Now that it's shut down, we still accelerate the beam in the Booster and Main Injector, but we send it directly to the experiments that need it," Johnson said.

The walls of the MCR are plastered with computer monitors. Joe gestured to the eight computer monitors above her desk that vertically ascend two by two until they reach the ceiling. These eight screens act like EKG machines, monitoring the proton beam as it passes to the various different experiments.

Since the Tevatron shut down, the scientists and engineers responsible for its upkeep have focused on the other experiments that hunger for more beam. The need for beam continues to increase as Fermilab pushes further into the Intensity Frontier.

As for MCR, it's business as usual. Fermilab still beats to the rhythm of the bloops and beeps that tell the MCR operators "all clear" or "something's wrong." If something isn't working properly, the MCR is the first place to know. It is manned 24 hours a day, 365 days a year and will continue to be as Fermilab transitions to the next frontier.

"We are the first line of defense if anything goes wrong," Joe said. "If there is a problem, we know about it, and we find a way to fix it."

Neutrinos faster than the speed of light? Not so fast...

From the LA Times, March 17, 2012.

Faster-than-light neutrinos, we hardly knew ye.

Back in September, a group of physicists working at the OPERA experiment (oscillation project with emulsion-racking apparatus) at Italy's Gran Sasso Laboratory astounded the scientific world by clocking neutrinos, a type of subatomic particle, that seemed to travel faster than the speed of light.

It was a feat that had been considered impossible, so the scientists asked colleagues to double-check the result. If the measurement panned out, it would call a century of physics into question, forcing scientists to rethink fundamental laws of the universe.

But on Friday, another experimental group at Gran Sasso, ICARUS (imaging cosmic and rare underground signal), reported that it had clocked seven neutrinos traveling the exact same underground path underground as the OPERA neutrinos ... and those neutrinos did not exceed the speed of light, after all.

The book isn't completely closed on those faster-than-light neutrinos — at least three more experiments to test the OPERA result are still in the works at Gran Sasso, as well as separate efforts in Japan and the U.S. — but Friday's announcement adds to a growing collection of evidence that something was amiss with the original claim.

High Energy Physics Advisory Panel meeting overview

Fermilab Director Pier Oddone

The High Energy Physics Advisory Panel met early last week, and several important topics were on the agenda, notably the FY13 budget request, planning for the future of our field and comparative reviews for DOE grants.

HEPAP gives advice to both DOE and NSF on the national particle physics program, and last week's meeting included reports from Office of Science Director Bill Brinkman, Jim Siegrist from the DOE Office of High Energy Physics and NSF. The DOE reports acknowledged that the three lower-priority programs in the Office of Science - nuclear physics, particle physics and fusion - are under a lot of budgetary stress. In particle physics, the stress is concentrated at Fermilab since the President's budget request limits our large international projects. DOE will report its plans to Congress on one such project, the Long-Baseline Neutrino Experiment, by the beginning of April.

There were also reports on the successful Intensity Frontier Workshop, DOE's progress toward a 10-year Intensity Frontier strategy and on the work of the Task Force on Accelerator R&D, all of which are extremely important to Fermilab and to the US program. DOE and NSF both also described plans for selecting the next generation of dark-matter experiments. Fermilab has several technologies in contention and we have a lot of work ahead of us to prepare for the competition.

The chair of the APS Division of Particles and Fields reported on plans for a Snowmass meeting in June of 2013, which will be preceded this October 11-13 by a preparatory Community Planning Meeting at Fermilab. These meetings bring the community together to take stock of where we are and analyze the most promising directions for our field. New LHC results, recent neutrino-physics results, and the advances in dark-energy, dark-matter and intensity-frontier experiments will all have a major influence at the meeting.

Another subject of much interest at this HEPAP was the new methodology of DOE reviews for university groups. Instead of each group being reviewed separately for its entire program, as had been done in the past, university groups who perform research in the same area were reviewed comparatively to select the strongest principal investigators. Some 25 percent of existing PIs were not funded after this review, while the overall number of PIs stayed roughly constant, allowing more new PIs to be funded. The lesson for Fermilab in this era of much tougher reviews is that we must manage our programs in a very rigorous way, with no weaknesses whatsoever. We often have the largest effort of any laboratory in any given program or project, and each part of the program and each researcher will need to be equally strong or risk being trimmed to divert resources to efforts elsewhere.
