The future of Fermilab
1 February 2012 | Source: Physics World
In this month’s Physics World, reviews and careers editor, Margaret Harris, visits the Fermi National Accelerator Laboratory (Fermilab) to explore what future projects are in the pipeline now that the lab’s Tevatron particle accelerator has closed for good.
After more than 25 years of groundbreaking discoveries, the Tevatron accelerator has finally surrendered to the mighty Large Hadron Collider (LHC) at CERN, placing Fermilab, in some people’s minds, on the brink of disappearing into obscurity.
However, the lab appears to be moving into a new frontier, with several new projects ready to step out of the shadow of the Tevatron and excel in many more areas of science. The excitement among the researchers working at the Chicago-based lab over the new developments is clearly conveyed in this feature.
Fermilab can no longer compete with the LHC when it comes to smashing particles together at high energies, but it can look for rare interactions between particles at lower energies. In this type of experiment, the key is not a beam’s energy but its intensity: the number of particles produced per second.
The lab’s plans include two experiments – one already being built and another in the pipeline – that will send beams of neutrinos underground to distant detectors to see how these particles change between one form and another.
More ambitious still is Project X – expected to cost between $1-2bn – which will provide intense beams of protons for experiments on neutrinos, rare decays and heavy nuclei. Beyond high-energy physics, the lab also participates in experiments on cosmic rays, dark matter and dark energy.
One obstacle that stands in the way of Fermilab’s progress is money. With the US Congress’s budgetary process – which allocates funds one year at a time – threatening to delay projects, combined with the current economic downturn, there is cause for concern, especially for a lab that is currently in transition.
“This is an opportunity for the US to establish a leadership position in this very important area of physics that will last for decades,” says Fermilab physicist Steve Holmes. “If we do it right, we’ll just blow away the competition.”
