More knobs, more knowledge

Long-bunch-train ILC studies are back at FLASH

by Barbara Warmbein

In their unflagging quest to achieve higher gradients for the ILC, scientists in the 9-mA study programme at DESY’s FLASH facility develop a better knack for automating accelerator voltages, helping keep cavity gradients high and the whole system stable.

Triple milestone for Cornell’s ERL programme

by Leah Hesla

Researchers at Cornell University's Energy Recovery Linac programme recently achieved three milestones in two months. One of them could lead to more reliable superconducting accelerator cavities.

Advances in SCRF cavity performance in the Technical Design Phase

This week's issue features a Director's Corner from Akira Yamamoto, Project Manager for the Global Design Effort

by Akira Yamamoto

As a result of the continued improvement of cavity processing and a better understanding of the gradient limit, researchers are closely approaching their design goals, with the hope of reaching them by the end of 2012.

At KEK's superconducting RF test facility, better known as STF, scientists are conducting beam tests of their photocathode RF gun towards beam operation of the accelerator for the Quantum Beam Project. On 22 March, scientists succeeded in the extraction of a 1-millisecond beam for a 162.5-megahertz bunch train. Pictured here is a signal from the beam position monitor (blue) and a laser gate signal (violet).

    The budget for the Department of Energy’s Office of Science would increase by 2.4 per cent to $4.992 billion, but high-energy physics would be reduced by 1.8 per cent to $777 million. …The proposed cuts in high-energy physics would hit two long-term programmes the hardest: the Long-Baseline Neutrino Experiment (LBNE) and the US R&D programme for the International Linear Collider (ILC).

    Bill Brinkman, director of the DOE’s Office of Science, wrote to Oddone to ask that Fermilab build the LBNE in stages. “I would like Fermilab to lead the development of an affordable and phased approach that will enable important science results at each phase,” he wrote.

    At a projected $1.5 billion, the Long-Baseline Neutrino Experiment (LBNE) at the Fermi National Accelerator Laboratory (Fermilab) in Batavia, Illinois, is not affordable, says William Brinkman, director of DOE’s Office of Science. So this week he asked physicists to come up with a cheaper way to do the same science.
