Green Bank RFI Team, September 2003
The task of the Radio Frequency Interference team in Green Bank is to ensure that on-site and local sources of radio frequency interference are nulled. The Green Bank Observatory sits inside the Radio Quiet Zone, a 13,000 square mile radio protection zone set aside by the federal government. The truck is equipped with antennas to pinpoint sources of interference around the countryside. Even a short in a heating blanket miles away from the Green Bank Telescope will be seen clearly by the GBT and ruin its astronomical observations. Microwave ovens in the buildings here get their own shielding boxes called "Faraday cages." Standing: Carla Beaudet, Wes Sizemore. Sitting: Jeff Acree and Denise Wirt. (GBRFIteam_large.jpg)
