Leah Hesla | 26 August 2010Achieving resonance in a scientific collaboration is no small feat, but scientists at Fermilab, DESY and KEK have come together to do exactly that: They've improved the mechanism that keeps superconducting radio frequency cavities in tune.Members of Fermilab's Technical Division and DESY staff, with financial assistance from KEK, recently built four new tuning machines that set SRF cavities to the correct frequency and alignment. More highly automated than their predecessors, the machines save time and labor and ensure greater consistency in RF cavity quality. They work by squeezing or stretching individual cells in a nine-cell cavity and allowing all of them to perform identically and impart the same acceleration to the beam.

Leah Hesla | 12 August 2010Last May, in only two weeks' time, a team of Accelerator Division Instrumentation Department employees installed, powered, debugged and started up a brand new, home-made beam position monitoring system at KEK's Accelerator Test Facility. It worked flawlessly.

29 July 2010Batavia, Ill.—New constraints on the elusive Higgs particle are more stringent than ever before. Scientists of the CDF and DZero collider experiments at the U.S. Department of Energy’s Fermilab revealed their latest Higgs search results today (July 26) at the International Conference on High Energy Physics, held in Paris from July 22-28. Their results rule out a significant fraction of the allowed mass range established by earlier experiments.

22 April 2010It is perhaps fitting that the New Muon Lab, a long, low concrete affair facing open fields, sits facing the northern edge of Fermilab’s property. The hangar-sized building is a busy place these days, home to the laboratory’s Superconducting Radio Frequency Test Facility, and bustling with the work that keeps Fermilab pushing the boundary of high-energy particle physics research.

4 March 2010With the quiet, deft manner of a jeweler showing his wares, physicist Cai Xiao opened a black box that, in a James Bond movie, might hold a stash of diamonds. This one held something every bit as precious. Inside lay a small, green circuit board topped with three shining silver strips: a silicon detector.

Elizabeth Clements | 10 September 2009In August, the Department of Energy announced that the American Recovery and Reinvestment Act will provide Fermilab with $52.7 million to test and develop superconducting radio frequency cavities, a key technology for next-generation accelerators and the future of particle physics. The funds provide a significant boost to the SRF program at Fermilab, allowing the laboratory to expand its test facilities and strengthen American manufacturing capabilities.

Gerrit Hörentrup (DESY) | 27 August 2009When groups from different countries work together the usual procedure is to send the people to the machines they are working on. A team of engineers and technicians from DESY, Fermilab and KEK decided to do the exact opposite: they sent the machines to the people. On 3 August two machines constructed at DESY embarked on a voyage to Fermilab in the US.
