What’s New

​Will particle physicists ever have a new toy that will take them to energies beyond those accessible through the Large Hadron Collider? History suggests it's unlikely. To save costs, the LHC was built in an existing tunnel that had hosted an earlier, less powerful accelerator. The US cancelled the construction of hardware that would have outperformed the LHC (the Superconducting Super Collider, or SSC) due to cost overruns, and it shut down its Tevatron once the LHC started up. Now, decisions on the linear collider that will be used to study the Higgs in detail are being made based on which country is likely to come up with the most money.

But physicists are apparently an optimistic bunch. Earlier this year, CERN announced that it was beginning to evaluate an LHC replacement that would require a tunnel so large—100km in circumference—that it would have to pass under Lake Geneva itself. Potentially in response, a team of US-based physicists have come up with an even more audacious plan: don't build the linear collider, resurrect the SSC's now abandoned tunnels, and use them to both host a Higgs factory and as a booster for a truly massive, 270km collider.

In Cadarache, France, the CEA-Euratom tokamak Tore Supra is undergoing a major transformation to be used as a test bench for ITER. This is the WEST project (W - for tungsten - Environment in Steady-state Tokamak).

The February issue of the WEST newsletter is now available online.
