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 […]
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) […]
Part one of a series on how a storage ring at Cornell University morphs into a damping ring test accelerator
Sometimes even pretty straightforward and remarkably logical ideas take several moves before they become a reality. Take the planned damping rings for the ILC, for example. In the ILC, compact bunches of electrons and positrons are made to collide at very high energy. In order to ensure a high rate of particle collisions, the bunches […]
Experiments in the PEP-II accelerator have shown that beam pipes with grooves can snare unwelcome electrons, greatly reducing the formation of electron clouds that can disturb the beam. While electron clouds presently pose little threat to the PEP-II beam, they are a major concern for the International Linear Collider (ILC) or a future B-factory project. […]
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 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 […]
