That article did not say very much.

Will it be some synchrotron-radiation light source? There are already several accelerators that do that, and the Tevatron could be repurposed as one. But the rumors I've seen is that it will be used as a neutrino source. Its accelerated protons will get smashed into a stationary target instead of other accelerated particles. The particles produced will produce lots of particles as they decay, some of them neutrinos.

Will it be some new high-energy one accelerator? In the fashion of the LHC succeeding the LEP in its tunnels. That would be awfully expensive, and require superconducting magnets capable of making much stronger fields than the Tevatron's could.
