No more HF?

| 26 September 2013 In June, Fermilab researchers finished successfully processing and testing the second single-cell, ILC-type cavity that was electropolished with a new technique. The water-based process, which doesn’t require the use of strong acids as the standard technique does, was developed to be more environmentally and worker-friendly.

How to keep cavities blemish-free

| 14 July 2011 Worrying about blemishes on the skin is not just an issue for people who pursue personal physical beauty, but also for accelerator scientists. Scientists and engineers at KEK have found a way to deal with unwanted stains on the inner surface of superconducting cavities, which might be one of the causes of performance limitation.

From Fermilab Today: Introducing the ICPA: The right tool for the right job

24 November 2010 Developing and improving superconducting radio-frequency technology is an important goal for Fermilab. SRF technology allows us to conceive and plan for future accelerators, such as Project X, the ILC or the Muon Collider, or for energy production applications such as Accelerator Driven Systems. One thing that will help this goal is a new facility that we will start up next year in the Technical Division, named the Integrated Cavity Processing Apparatus.

Jefferson Lab’s rules for achieving spotless cavities

| 18 November 2010 A research team at Jefferson Lab has developed its own detailed set of rules for optimal cleaning. Team members have been working on a regimen for removing imperfections and impurities from superconducting radiofrequency (SRF) niobium cavities. Their procedures, they believe, have helped create cavities that could exceed ILC 2010 performance benchmarks. Category: Feature | Tagged: , , ,

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

5 February 2009 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.

Polishing the safety standards

| 27 March 2008 Superconducting cavities are the core, the heartbeat of the International Linear Collider. Their inside will be polished to literally make them sparkle without any speck of dust or crack because these could cause a decline of performance of the accelerator. There are several methods to polish the inside of the cavities, and electropolishing (EP) is one of them. The new EP system at KEK has started its test-run in January, and scientists are gathering basic data to evaluate the machine's capability. Category: Around the World | Tagged: ,

Cornell University Moves Forward on Vertical Electropolishing

| 15 March 2007 Recent results from Cornell University demonstrated that a new method of electropolishing superconducting cavities may hold promise for the International Linear Collider. For the past two years, Cornell scientists have been developing an electropolishing method that treats cavities vertically as opposed to the traditional horizontal orientation developed by KEK. Cornell recently applied this new vertical method to a nine-cell ILC cavity for the first time and achieved positive results. “This is the first step to show the viability of the new method,” says Cornell physicist Hasan Padamsee.
