Over the next three years, Burrows will be engaging with the institutes that are members of CLIC and helping to ensure that CLIC’s R&D programme pushes ahead during the critical phase ahead of the next update of the European strategy for particle physics. Corsini will continue his technical leadership of CLIC/CTF3.

Burrows, who is an expert on fast-feedback and feed-forward beam correction systems (studied at KEK’s ATF2 and CERN’s CTF3 test facilities for future linear colliders) and on the machine-detector interface, is the first non-CERN CLIC accelerator spokesman. “I hope to cultivate the collaboration spirit and maximise opportunities for the international CLIC accelerator collaboration,” he says. The CTF3 test facility will probably stop operating in its current mode within the next couple of years, so changes are ahead for CLIC. “There are several promising avenues to explore, including exploring opportunities for novel applications of CLIC technologies.”

The most recent European strategy for particle physics was published in 2013. Recognising the international collaborations that will be needed to make scientific advances, it sets out the future priorities for European particle physics research. The strategy is due to be updated in 2018, and that’s likely to be the timescale for decisions on the future direction for CLIC. With other potential successors to the Large Hadron Collider (LHC) on the table, Burrows says there will be tough decisions to be made about the best choice for the next big particle physics machine in Europe. “Any future proposed project would be expensive to build. We might be able to afford one in Europe, but definitely not two or more.”

“CLIC remains the only viable technology today that could take us to multi-TeV centre of mass electron-positron collisions,” he says. “But we need more LHC results to assess whether it is the right machine to take us into new areas of physics research. LHC results over the next few years of running at higher energy and luminosity will be key to determining the way forward.”

Using the CLIC Test Facility (CTF3), the key concepts of CLIC have already been tested and proved. Probably the most innovative element of the CLIC design is that it has two beams – a drive beam and a main beam. “We’ve demonstrated that it is possible to transfer energy from the drive beam and feed it to the main beam,” says Burrows. “Now we need to work on more of the technical implementation and system optimization, not least how to mass produce the components that we need – essential for keeping the cost of the project as low as possible.”

CLIC collider

For the next few years, the focus is definitely on CLIC R&D, but Phil will undoubtedly have more than half an eye on results coming out of the LHC when it starts operating again in 2015.

The Linear Collider Collaboration is an organisation that brings the two most likely candidates, the Compact Linear Collider Study (CLIC) and the International Liner Collider (ILC), together under one roof. Headed by former LHC Project Manager Lyn Evans, it strives to coordinate the research and development work that is being done for accelerators and detectors around the world and to take the project linear collider to the next step: a decision that it will be built, and where.

Some 2000 scientists – particle physicists, accelerator physicists, engineers – are involved in the ILC or in CLIC, and often in both projects. They work on state-of-the-art detector technologies, new acceleration techniques, the civil engineering aspect of building a straight tunnel of at least 30 kilometres in length, a reliable cost estimate and many more aspects that projects of this scale require. The Linear Collider Collaboration ensures that synergies between the two friendly competitors are used to the maximum.
