Accelerator builders should step back and re-assess decades of R&D into superconducting RF technology says Jefferson Lab’s Ganapati Rao Myneni. Nearly a half-century ago, researchers at Stanford University began investigating superconducting RF (SRF) acceleration. They would not have been surprised to learn that by 1994, SRF had come into large-scale use in Jefferson Lab’s Continuous Electron Beam […]
From Jefferson Lab News: ILC Electron Source Gets Help from JLab
With the activation of the LHC, or Large Hadron Collider, some particle physicists are now looking forward to the next big machine. For many, that’s the International Linear Collider. The ILC aims to break new ground in particle physics by slamming a beam of electrons into a beam of the electron’s alter ego: the positron. […]
Progress and plans for ILC R&D at JLab
Director’s Corner 16 October 2008 Barry Barish Progress and plans for ILC R&D at JLab Jefferson Laboratory (JLab) in Newport News, Virginia, is a major DOE laboratory for Nuclear Physics. The laboratory has a pioneering 6-GeV electron accelerator that is based on superconducting radiofrequencey (RF) accelerating technology. JLab has a great deal of expertise, experience […]
US-manufactured cavity achieves high gradient
Turkey, stuffing and pumpkin pie – all things you might appreciate on Thanksgiving. ILC scientists in the United States had something extra to be thankful for this year. On 21 November, the day before the Thanksgiving holiday in the US, a superconducting cavity manufactured by Advanced Energy Systems in Medford, NY, reached a high gradient […]
From Jefferson Lab News: Jefferson Lab Cooks Up the Perfect Cavity
While it’s said that opposites attract, particle physicists are taking no chances. In hopes of learning what the universe is made of, they’re preparing to build a machine that will accelerate and smash together electrons and their opposites, positrons, 14,000 times every second. Like Jefferson Lab’s Continuous Electron Beam Accelerator Facility (CEBAF), the proposed new […]
Argonne-Fermilab BCP System Coming Together
To make the superconducting cavities for the ILC sparkle, they must undergo a series of surface treatments to make them as clean and pure as possible – a necessity for achieving high accelerating gradients. Electropolishing and Buffered Chemical Polishing, the two types of chemical treatments required for the cavities, are not simple tasks. They involve […]
