From Jefferson Lab News: ILC treatment of JLab cavity garners exciting result

Before the ILC-style electropolish, the accelerating gradient of this Jefferson Lab accelerator cavity topped out near 17 megavolts per meter (MV/m), a measure of the cavity's ability to impart energy to electrons. After processing, the cavity's accelerating gradient jumped to 35 MV/m.
For the last few years, Jefferson Lab staff members have used the lab's unique facilities to test various accelerator components for a proposed next-generation collider, the International Linear Collider. Reminiscent of a stack of doughnuts, accelerator components called cavities energize particles for use in experiments that explore the smallest bits of matter.

Feature Story
ECal: a piece of the jigsaw reaches a milestone

The generic motherboard designed at LPC, testing the analogue-to-digital converter prototype.
Hundreds of millions of channels of electronics: this is about what the electromagnetic calorimeter (ECal) of the CALICE collaboration will have to design, process and analyse. The very high granularity of ILC detectorís future calorimeter will also be reflected in the ambitious first-stage electronics Ė or very-front-end electronics, which still needs to be designed. One part of the electronic jigsaw is the analogue-to-digital converter (ADC). At LPC, a CNRS/IN2P3 lab in Clermont-Ferrand, France, the latest ADC prototype fulfills the ILC requirements in terms of resolution, compactness, time of conversion and power consumption.

From JLab: Second chance
This accelerator cavity was worn out. It had been washed, baked and tested so much that its performance suffered, eventually declining below minimum specs. Researchers undertook a last-ditch effort to breathe new life into the beleaguered cavity and were rewarded with an astounding result. Read more in today's Around the World story (Photo: JLab)

If we donít provide these experimental facilities, eventually people just arenít going to come here, and weíll be left in the dust.

FALC meets in Madrid

Walter Davidson, new secretary of FALC, and Pierre Coulombe, new chair of FALC
The Funding Agencies for Large Colliders (FALC) held its semi-annual meeting in Madrid, Spain on 19 January. FALC is an informal group of agency and government representatives that provides oversight for the Global Design Effort on resource and project planning matters. More broadly, FALC is a forum for information exchange for agency and government representatives from the different countries, especially regarding major international initiatives in particle physics. The Madrid meeting marked the transition of the chairmanship of FALC from Roberto Petronzio (the National Institute of Nuclear Physics INFN, Italy) to Pierre Coulombe (National Research Council, Canada). The meeting had two components: presentations of science in Spain and discussions of the worldwide particle physics programme, including planning for the International Linear Collider, by FALC.
