Clustering klystrons to pool power

An elegant powering scheme accommodates the ILC’s new one-tunnel design.

by Leah Hesla

Though it doesn’t sound like a way to tidy up, the alliteratively named klystron cluster could be the mechanism that helps streamline the large-scale design of the ILC.

Scientists at the Stanford Linear Accelerator Center (SLAC) in the US are currently developing the klystron cluster scheme, a new kind power-delivery system for radio frequency cavities that distributes power from a common conduit.

From CERN: CERN announces LHC to run in 2012

Geneva, 31 January 2011. CERN today announced that the LHC will run through to the end of 2012 with a short technical stop at the end of 2011. The beam energy for this period will be 3.5 TeV. This decision, taken by CERN management following the annual planning workshop held in Chamonix last week and a report delivered today by the laboratory’s machine advisory committee, gives the LHC’s experiments a good chance of finding new physics in the next two years, before the LHC goes into a long shutdown to prepare for higher energy running starting 2014.

Taking heed of good advice

by Barry Barish

The most obvious benefit of the seemingly endless series of reviews we undergo comes from the rigours of doing our preparations. But the reviews also serve to validate our work, and perhaps most importantly, the review committees give us good advice in their reports. Last autumn, we had a two-day technical review of the Global Design Effort by the Project Advisory Committee (PAC), a subcommittee of the International Linear Collider Steering Committee (ILCSC). Several recommendations came out of that PAC review that have been quite helpful to us as we prepare to make final decisions on the proposed new baseline configuration for the ILC Technical Design Report (TDR).

    …globally other countries have interests (…) in developing the next generation of accelerator facilities for particle physics. There’s going to be cooperation in trying to leverage the funds globally in order to spend the most wisely in terms of R&D that will position the countries interested in doing this in the future.

    If nature is kind to us and the Higgs particle has a mass within the current range of the LHC, we could have enough data in 2011 to see hints (…) Running through 2012 will give us the data needed to turn such hints into discovery.
