QuickField is successfully used in major scientific project - The Spallation Neutron Source (www.sns.gov), an accelerator-based neutron source being built in Oak Ridge, Tennessee, by the U.S. Department of Energy. The SNS will provide the most intense pulsed neutron beams in the world for scientific research and industrial development. At a total cost of $1.4 billion, construction began in 1999 and will be completed in 2006. Here is the letter from Dr. Robert Welton describing QuickField role in his researches (resulting in the article "The design of high power, external antennas for radio frequency multicusp ion sources" by R.F.Welton, M.P.Stockli, R.T. Roseberry , Y.Kang, R. Keller published in the Review of Scientific Instruments, v. 75 number 5).
