(Nov. 16, 2011) — CERN has kicked off the High Luminosity LHC (Large Hadron Collider) study with a workshop bringing together scientists and engineers from some 14 European institutions, supported through the European Commission's seventh Framework programme (FP7), along with others from Japan and the USA. The goal is to prepare the ground for an LHC luminosity upgrade scheduled for around 2020. Luminosity is gives a measure of the brightness of the beams, and hence the collision rate in a particle accelerator and therefore gives an indication of its performance.

The LHC already delivers the highest luminosity brightest beams of any Hhigh Eenergy proton accelerator in the world, which is vitally important for physicists wanting to study extremely rare processes.

"With the LHC colliding hundreds of millions of particles each second, some of the processes we're interested in will happen just a few times a day" explained CERN Research Director Sergio Bertolucci, "with processes so rare, extra luminosity makes a big difference to our ability to make precision measurements and discover new things."

This week's workshop launches the initial design phase of the project, which aims to take the LHC's luminosity to a factor of 5-10 above its current design value. It draws on expertise from around the world, bringing together scientists from the well-established CERN-KEK collaboration and US LHC Accelerator Research Program (LARP) with a new European Design Study networksupported under FP7. This international nature is representative of the field of particle physics, and vital for its success of the project.

"We have set up a collaboration in which all partners are involved at the same level," said High Luminosity LHC project coordinator, Lucio Rossi. "While we were building and commissioning the LHC, LARP and KEK were developing new technologies for the next generation magnets. Their research and development activities will be key to our success."

Upgrading the LHC for higher luminosity will require new technologies to be developed in a range of fields including high field13 tesla tesla superconducting magnets, transverse RFradiofrequency cavities and GW class d.c. electrical transfer lines,. aAll based onthese new components are based on superconductivitysuperconducting technology.

"All these new technologies require further study but the project's partners have the necessary know-how to successfully develop them," explained Rossi. "At the kick-off meeting we will synchronize our work to increase synergies among the partners, touching base on what has been done so far and define future milestones."
