CesrTA collaborators work to improve the ILC’s damping ring design
The CesrTA (Cornell Electron Storage Ring Test Accelerator) collaboration at Cornell University, US, made important contributions to the design of the ILC damping rings for the recently completed Technical Design Report, including finding ways to reduce a phenomenon known as the electron cloud effect. Post-TDR, the collaboration is pursuing ways to make the damping rings […]
The next generation of particle accelerators will contain intense bunches of particle beams. These intense beams have the disadvantage that they create electron clouds that result from beam scattering off residual molecules in the vacuum chambers. The concern is that the presence of electron clouds can reduce performance by scattering and defocusing the incoming particle […]
Taking on white papers and electron clouds, Mark Palmer brings his own energy to the CesrTA programme.
For many involved with the ILC, Mark Palmer exemplifies what it means to be a nexus. Palmer is the connection between the Cornell Electron-Positron Storage Ring Test Accelerator (CesrTA) programme – a prototyping project for the ILC damping ring – and the larger ILC community. Working with his team at home and taking their findings […]
Director’s Corner 11 November 2010 Barry Barish Electron-cloud physics What is and what causes an electron cloud in a modern accelerator? What problems does it create on accelerator performance and how can its effects be mitigated? This was the subject of a special workshop at Cornell University held from 8 to 12 October 2010, sponsored […]
Researchers at SLAC and other institutions are creating a sort of pest control for particle beams: squashing the clouds of electrons that gather in accelerators and disrupt experiments. “Some methods are already there… we know they work,” said Mauro Pivi, a SLAC scientist in the Accelerator Design Department. But in order for future colliders such […]
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 […]
A profile of Susanna Guiducci, ILC damping ring group leader
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 […]
How CERN’s accelerator complex fights electron clouds
The ILC is not the only accelerator that has to struggle against electron clouds and their distracting effect on the particle beam. Even the Large Hadron Collider LHC at CERN may suffer from it, and tests on two of its pre-accelerators, the PS and the SPS, have already proven several techniques with which the electron-cloud […]
Director’s Corner 12 March 2009 Barry Barish The ILC damping rings and electron cloud mitigation 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 […]
