From CERN Bulletin: The collider of the future?
The recent ILC-CLIC meeting (see two recent Director's Corner about the meeting and about Jean-Pierre Delahaye joining the Executive Committee for more information) was also covered by CERN's internal newsletter Bulletin. We feature the article here today.

A view of the two beam lines in the CLIC experimental hall.
The International Linear Collider (ILC) and Compact Linear Collider (CLIC) studies both call for cutting-edge technologies. At first glance they may appear to be in competition, but they are in fact complementary and have a common objective – namely to propose a design, as soon as possible and at the lowest possible cost, for the linear accelerator best suited to taking over the baton of physics research at the high-energy frontier after the LHC.

Feature Story
3-D silicon technology project draws together industry and research for ILC

The bonding of two electronic tiers using the oxide-oxide Cu-Cu thermo-compression technique employed by Tezzaron.
The International Linear Collider had more than a dozen circuit pixel-detector technologies to choose from for their vertex detectors. Now, they can choose from many more design options thanks to a ground-breaking partnership among national laboratories, universities and industry.

Improvements in high-gradient ILC SCRF cavities

Recent results on cavity yields from JLab and DESY approach our TDP-1 goal of 50% yield at 35 MV per metre
Developing high-gradient superconducting radiofrequency (SCRF) nine-cell cavities is one of the primary goals of our global R&D programme. Soon after we initiated the Global Design Effort (GDE) R&D and design programme for the International Linear Collider, we set the ambitious goal of 35 Megavolts (MV) per metre as our gradient. If we succeed, we plan to set an average operating gradient of 31.5 MV per metre for the 14560 cavities mounted in the 1680 cryomodules of a 500-GeV ILC. Major efforts towards high-gradient cavities are underway in the Americas, Asia and Europe and we have recently made good progress that makes us believe our goals are within reach!

Accelerators everywhere!

A single-cell niobium cavity was one of the many exhibits that showed that accelerators are 'everywhere: from the Big Bang to curing cancer'. In one of 25 stands of the Royal Society's Summer Exhibition — a popular event by the UK's national academy for science that attracted more than 5000 visitors in a week — a team of accelerator experts from labs and universities across the UK showed how exciting, useful and versatile the big machines are.
