Brilliant! So does this mean we might actually have work again someday?

The Super Large Hadron Collider (SLHC) is a proposed upgrade to the Large Hadron Collider to be made around 2012. The upgrade aims at increasing the luminosity of the machine by factor of 10 to 1035 cm−2s−1, providing a better chance to see rare processes and improving statistically marginal measurements. There exist many different paths to the upgrade. A collection of different designs of the high luminosity interaction regions is being maintained at [1]. A workshop was held in 2006 to establish which are the most promising options [2]. A comprehensive press article on this workshop can be found at the CERN Courier. A summary of the possible machine parameters can be found at Machine parameters collection.

Increasing LHC luminosity involves reduction of beam size at the collision point and either reduction of bunch length and spacing, or significant increase in bunch length and population. The maximum integrated luminosity increase of the existing options is about a factor of 4 higher than the to the LHC ultimate performance, unfortunately far below the LHC upgrade project's initial ambition of a factor of 10. However at the latest LUMI'06 workshop [3], several suggestions were proposed to boost the LHC peak luminosity by another factor of 10 beyond nominal towards 1035 cm−2s−1.

The resultant higher event rate poses important challenges for the particle detectors located in the collision areas[4].

Sorry but the linkjs [1] to [4] are not expandable in this forum representation. Please include them as full text. They seem to be very interesting proposals.
