Dear STC-ETC Colleagues and Friends, The date for the Spallation Neutron Source tour is April 8. We currently have a full complement for one tour guide. An accurate count will ensure we get a second tour guide if needed. Please send me an email if you would like to attend and I will provide information on security, meeting place, and time. Here is a blurb on this wonderful facility (how many people in the world can claim seeing it!): SNS is a one-of-a-kind research facility that provides the most intense pulsed neutron beams in the world for scientific research and industrial development. SNS produces neutrons with an accelerator-based system that delivers short (microsecond) proton pulses to a target/moderator system, where neutrons are produced by a process called spallation. State-of-the-art experiment stations provide a variety of capabilities for researchers across a broad range of disciplines, such as physics, chemistry, materials science, and biology. (See https://neutrons.ornl.gov/sns for more information.) Best wishes, Mary Mary Ryba Knepper Treasurer, STC-ETC, 2015-2016 708.738.8178 mobile
