LHC milestone: two simultaneous circulating beams

Celebration on Friday in the LHC Central Control Room at CERN after operators established a circulating clockwise beam at 4 p.m. EST.

CERN's Director for Accelerators Steve Myers announced today that for the first time two beams are circulating simultaneously in the LHC. The announcement was made at a press conference held at the laboratory. The first individual circulating beams of 2009 were successfully established on Friday, November 20.

The next steps will be a careful, systematic testing of the accelerator.

"We will systematically go through all the measurements, put all the systems through their tests, and when we're sure everything's safe, we will increase the beam intensity," explained Myers. "During some shifts we will try to accelerate beam to the maximum energy for this year - 1200 GeV per beam. Then we will decide about collisions. Two possibilities are to collide at the 450 GeV injection energy or at 1200 GeV per beam. That is our program until just before Christmas." Over the next year, the energy will be ramped to 3.5 TeV (3500 GeV) per beam, and then possibly to a maximum of 5 TeV.

"With 3.5 TeV per beam we will open new windows to new physics," noted CERN Director-General Rolf Heuer.

Fabiola Gianotti, spokesperson of the ATLAS experiment, observed, "This is at the same time the end of twenty years of effort by the international scientific community to build a machine and detector of unprecedented complexity and technological challenges, and the beginning of a fantastic era of physics exploration and discovery."

LHC starts circulating protons in two directions

From Times Online, Nov. 23, 2009

Beams of protons are circulating in both directions around the Large Hadron Collider (LHC) for the first time, after it was restarted on Friday following a 14-month shutdown for major repairs.

CERN scientists said the achievement, made this morning, brings the 5bn "big bang machine" closer to full operation and sets the stage to start smashing particles within weeks.

Detectors around the LHC's 27km (17 mile) ring have already started to detect traces of collisions between particles in the beams and equipment, showing that they are in good working order.

Engineers may now bring the two beams together in the next few days to stage small collisions to help scientists to calibrate the detectors, with higher-intensity collisions scheduled before Christmas. High-energy collisions for new physics are then expected in January.

More scientists treat experiments as a team sport

From The Wall Street Journal, Nov. 20, 2009

If all goes well, researchers Friday may power up the Large Hadron Collider — a $6 billion particle accelerator near Geneva. The atom smasher is so large that a brief status report lists 2,900 authors, so complex that scientists in 34 countries have readied 100,000 computers to process its data, and so fragile that a bird dropping a bread crust can short-circuit its power supply — as occurred earlier this month.

Far from trouble-free, the proton accelerator is resuming operations after a catastrophic breakdown in 2008 that triggered a year of repairs and recriminations. Its large research teams operate on such an elaborate scale that project management has become one of science's biggest challenges.

ES&H Tips of the Week - Safety safety

Are your building exits safe?

Safety inspectors at Fermilab found a bicycle obstructing this emergency exit. Exit pathways might look like unused storage space, but they are empty for a reason.

Having an emergency exit does little good if you can't get through it.

For exits to be useful, people must be able to find and navigate through them. Fire codes govern the placement and design of these exits for the safety of the buildings' occupants. Recent safety inspections at Fermilab found some emergency exits or pathways to emergency exits that were obstructed. It is part of every person's job to make sure that exit signs, lights and pathways are working, unobstructed and up-to-date.

Exit signs — The purpose of exit signs is to guide people to the best exit pathway in the event of fire or other emergency. You have probably seen them posted at exit doors and along paths of travel. Exit signs can fall short because they are not sufficiently apparent (due to placement or number), they are misleading, or, in the case of illuminated signs, because they are not lit.

Exit lights — These help to identify the exit pathway as well as afford visibility under low-light conditions. Common problems are misdirected, broken or limited lighting.

Snow and other debris can block or partially obstruct emergency exits.

Exit pathways — These should provide unobstructed routes that people can use for the prompt and safe evacuation of buildings. Unfortunately, the open space afforded by some exit areas can attract storage of miscellaneous items.

Most folks at Fermilab have little direct responsibility for the installation and maintenance of exit signs and lights. You should direct issues with these devices to the appropriate building manager. On the other hand, misplaced clutter is something that we can all work to remove. Please do your part to keep exit pathways clear.

Future colliders: Beyond the LHC

From New Scientist, Nov. 20, 2009

The Large Hadron Collider is by no means the last of the particle smashers. A group at CERN recently explored the various scenarios that might emerge from the atomic debris in Geneva – and how they would shape what colliders we build next. We draw out the key points about each of the scenarios.
