Four months before the Tevatron shuts down for good, physicists at Fermi-lab's giant particle collider near Bata-via, Illinois, are pulling out all the stops to collect every last bit of data that they can. But some worry about what will eventually happen to the trove of data - approaching 20 petabytes (20 x 1015 bytes) - amassed over the machine's 26-year life. Although there is funding to continue sifting the data for traces of the Higgs boson and other subatomic prizes for the next five years, so far there is no plan and no budget for preserving them in the longer term. At a workshop on data preservation at Fermilab on 16-18 May, some physicists called for that to change, arguing that Tevatron data could prove useful as an independent check on its successor, the Large Hadron Collider (LHC) now operating at CERN, Europe's particle-physics lab near Geneva, Switzerland. If researchers suspect that the LHC has spotted new physics, particularly at the lower end of its energy range, the claim could be tested for consistency with Tevatron data, says Rob Roser, spokesman for the Collider Detector at Fermilab (CDF), one of the Tevatron's two principal experiments.
