Physics at ILC and its status in Japan
Talk by Hitoshi Murayama (Kavli IPMU, Japan) on Wednesday 19 June from 11:00 to 12:00 (Europe/Paris) at LAL (Auditorium Pierre Lehmann). The talk will be webcast.
Barry Barish | 20 December 2012One of the key objectives of the ILC R&D programme during the Technical Design Phase has been to characterise electron cloud effects in an ILC-like low-emittance positron damping ring and to test proposed mitigation techniques. The centerpiece of our efforts has been the CesrTA programme that involved reconfiguring it as an ILC-like low emittance ring and instrumenting it to carry out these studies. CesrTA has been a highly successful experimental programme, leading to reliable mitigation strategies for the ILC positron damping rings.

Barbara Warmbein | 13 September 2012A team at DESY has created a complete virtual-reality three-dimensional ILC. They have combined information from various computer-aided design systems and about all areas of the ILC together in one model that you can now walk through. This model can highlight problems before they become costly and is a great motivator for the owners of the individual systems.

6 September 2012A recent workshop reviewed the latest experiences with the phenomenon of electron clouds at the LHC and other accelerators. Electron clouds – abundantly generated in accelerator vacuum chambers by residual-gas ionization, photoemission and secondary emission – can affect the operation and performance of hadron and lepton accelerators in a variety of ways. They can induce increases in vacuum pressure, beam instabilities, beam losses, emittance growth, reductions in the beam lifetime or additional heat loads on a (cold) chamber wall.

9 February 2012The 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

30 July 2009From 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.

Barbara Warmbein | 12 March 2009Susanna 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.”

Barry Barish | 12 March 2009Today'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

Barbara Warmbein | 11 December 2008When 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.
