Part three of a series on how the CESR storage ring turns into the CesrTA damping ring
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 […]
CesrTA kick-off meeting marks the beginning of the damping ring test programme
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 […]
Director’s Corner 5 June 2008 Barry Barish Critical electron cloud studies at Cornell 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) […]
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. In curved sections of accelerators, such as a damping ring, the beam throws off […]
In the end of January, the Laboratory for Elementary Particle Physics (LEPP) at Cornell University hosted collaborators from KEK, Lawrence Livermore National Laboratory, Argonne National Laboratory and Alfred University (an undergraduate University in New York State) to conduct electron cloud studies using the CESR storage ring. CESR is unique in that it is a “wiggler […]
Director’s Corner 14 December 2006 Gerry Dugan Cost Optimisation of Wigglers for the ILC Damping Rings Today’s issue features a Director’s Corner from Gerry Dugan, GDE Americas Regional Director. One of the key technical components of the ILC damping rings is the wiggler magnet, a device consisting essentially of a series of dipole magnets of […]
Director’s Corner 5 October 2006 Barry Barish The Evolving ILC Design: Eliminating One Positron Damping Ring We have planned from the beginning to quickly create an initial baseline and as a result of technical developments, evolve it in time. Our Baseline Configuration Document explicitly includes a number of alternatives that we consider to be very […]
Director’s Corner 11 May 2006 Barry Barish Baseline Damping Rings One of the more difficult decisions we made last fall was which damping ring option to choose for our baseline. No recommendation came out of the Snowmass Workshop and our damping ring working group continued to study the question through much of the fall. […]
Director’s Corner23 November 2005 Barry Barish Damping Ring RecommendationReaching the luminosity goals of the ILC will be an enormous challenge. It will require producing nanometer scale beam spots at the collision point and a crucial element in achieving this will be to ‘damp’ the beams that come from the electron and positron sources to have […]
