Fermilab has a new collaboration centre: on 27 August, the Korean Ministry of Education, Science and Technology and the Rare Isotope Science Project (RISP) of Korea’s Institute for Basic Science opened the Korea-US Collaboration Center for Accelerator Science (KUCC). Korea is planning to build in Korea by 2017 a rare-isotope accelerator, which will have SCRF technology […]
The US programme reduction
This week's issue features a Director's Corner from Mike Harrison, Americas Regional Director for the Global Design Effort
The 19th-century German statesman Otto von Bismarck said that laws are like sausages – it’s better not to see them being made. The US budget, when it finally appears, eventually becomes law. With the GDE mandate and the associated R&D programme for the ILC coming to an end with the final handover of the Technical […]
Q – cavity quality factor
Physicists need to understand each accelerator cavity individually before assembling a collider. One of the cavity characteristics physicists measure is called the cavity quality factor, Q factor for short. One way to understand the Q factor is to pick up a bell. Let the clapper tap the bell edge once. You’ll notice that just one […]
Superconducting radio-frequency
How do you accelerate particles in a particle collider? One answer is superconducting radio-frequency (SCRF) cavities. To give particles energy as they move through an accelerator, physicists use cavities containing electric fields that oscillate. The changes in electric field help push the particles from one cavity to the next. These oscillations occur with the same frequency […]
After the TDR: what’s next for ILC?
Today's issue features a Director's Corner from Marc Ross, Project Manager for the Global Design Effort.
“We are just standing at the entrance, and our world efforts need to continue or become even stronger.” These are the words Kaoru Yokoya used to close his ILC NewsLine Director’s Corner at the end of last year. (The italics are mine.) Six months later his words continue to ring true and are perhaps a […]
Cavities in the spotlight
The secret life of cavities – not so secret any more
Science photographer Heiner Müller-Elsner follows a cavity through all stages of production
Cavities will be the heartbeat of the ILC, accelerating electrons and positrons to very high energies so that they can collide in the centre of the detectors. The ILC’s core technology, superconducting radiofrequency technology or SCRF, is also used in other accelerators, for example FLASH at DESY of the future European XFEL. Because they are […]
The potential of superconducting niobium cavities
There are more than 30,000 particle accelerators in operation around the world. At Fermilab, US, scientists are collaborating with other laboratories and industry to optimise the manufacturing processes for a new type of powerful accelerator that uses superconducting niobium cavities. View video
Advances in SCRF cavity performance in the Technical Design Phase
This week's issue features a Director's Corner from Akira Yamamoto, Project Manager for the Global Design Effort
The current ILC superconducting radiofrequency (SCRF) cavity design is based on the so-called TESLA type (the elliptical shape as shown at left), a 1.3-gigahertz (GHz) nine-cell cavity. The design gradient has been set at 35 megavolts per metre (MV/m) and an average quality factor (Q0) of greater than 8×109 to realise the stable, long-term operation […]
PAC meeting in Taiwan: accelerator recommendations
The ILC Program Advisory Committee (PAC) held their semi-annual review of the ILC detector and accelerator programmes at Academia Sinica in Taipei, Taiwan from 19-20 May and made a set of specific recommendations regarding the GDE accelerator R&D programme towards a Technical Design Report (TDR). Overall, the review was quite positive and supportive of our […]
