The next-generation B factory to be built in Italy will reach new levels in luminosity by employing the innovative crab-waist scheme at the beam collision point. The SuperB concept represents a real breakthrough in collider design. The low-emittance ring has its roots in R&D for the International Linear Collider (ILC) and could be used as a system-test for the design of the ILC damping ring. The invention of the crab-waist final focus could also have an impact on the current generation of circular colliders. Read more in CERN Courier

As part of the process of developing the ILC technical design, the GDE project managers have initiated a set of technical baseline reviews of major subsystems. The first of those reviews on the ILC damping rings was carried out in July in Frascati, Italy.

[...] For the ILC, electron cloud effects can defocus the positron beam in the damping rings, thereby degrading the ability to create a low-emittance beam, a key in creating the required very small final beam spot.

From 25 to 26 June, about 40 attendees gathered at the Industrial and Labor Relations Conference Center at Cornell University in Ithaca, New York, to attend a workshop on the Cornell Electron Storage Ring Test Accelerator programme and to discuss R&D progress on the damping rings and electron clouds. It was the first dedicated workshop for interested and participating researchers, students, and physicists to talk about the state of the CesrTA project since its debut last year.

Susanna Guiducci has her head in the clouds – electron clouds, that is. (Sometimes she sits in clouds that gather around the Frascati hills south of Rome where she is based at the INFN Laboratori Nazionali di Frascati or LNF, but that is not really relevant to this story – just very picturesque.) As new leader of the damping ring group, one of the key R&D projects in the ILC’s Technical Design Phase, she also has her feet firmly planted in electron-positron accelerator physics and has been working on damping rings for ten years. All that experience gives her a clear picture of where the challenges lie in the ILC damping ring design, but she is confident: “I am convinced that the parameters set for the damping rings are feasible.”

Today's ILC Newsline is a thematic issue focusing on aspects of electron cloud mitigation for the ILC and for other future accelerators. One of the highest-priority goals of the ILC R&D programme during the Technical Design Phase is to demonstrate that the proposed mitigation techniques for the electron clouds in the damping rings will reduce the levels so that the clouds will not impact the emittance performance of the positron damping ring. --By Barry Barish

When you have a set of new hardware and a clear mission ahead of you, the first step to complete the mission is to commission the hardware. After reconfiguring their storage ring and light source CESR, Cornell University and the international ILC team working on damping ring studies switched on the machine in early October and performed the first electron cloud studies in the low emittance configuration in November. “It was an intense week and we have some very interesting new data,” says Mark Palmer, CesrTA project manager.

There may not have been a ribbon-cutting ceremony or speeches by heads of state. But the official kick-off of Cornell University's CESR storage ring as ILC damping ring test facility pleased the nearly 40 participants at this week's "Joint CesrTA Kickoff Meeting and ILC Damping Rings R&D Workshop (ILCDR08)" enormously. “CesrTA will give us a detailed picture of the how electron cloud builds up under a range of conditions, of how an ultra-low emittance positron beam interacts with the electron cloud, and of how beam instabilities driven by the electron cloud develop,” says Andy Wolski, damping ring group leader based at the Cockcroft Institute in the UK. “In this respect CesrTA plays a critical role in validating the decision to reduce costs by eliminating the second positron damping ring.”

Last week we reported on the beginning of our important experimental programme on electron cloud effects, using the Cornell Electron Storage Ring (CESR) accelerator at Cornell University. This is one of our highest-priority R&D goals during the ILC Technical Design Phase 1 (TDP-1) and is aimed at understanding the magnitude of the problem for the ILC positron damping rings and the effectiveness of our proposed mitigation techniques.

Clouds might be welcome during a drought, but you definitely don't want them in your beam pipes. Researchers around the world are working out how to keep a section of the proposed International Linear Collider—the positron damping ring—clear of electron clouds.
