DENSEST ARTIFICIAL IONOSPHERIC PLASMA CLOUDS PRODUCED USING HAARPResearch physicists and engineers from the Plasma Physics Division of the U.S. Naval Research Laboratory successfully produced a sustained high-density plasma cloud in Earth’s upper atmosphere. The team created the higher density plasma ‘ball’ using the High-frequency Active Auroral Research Program (HAARP) transmitter facility, in Gakona Alaska. The ‘ball’ was sustained for over an hour by the HAARP transmissions and was dispersed when the HAARP radio beam was terminated.The plasma clouds (or balls) were created using the 3.6-megawatt high-frequency (HF) HAARP transmitter, to be studied for use as artificial mirrors at 50 kilometres altitude below the natural ionosphere. They will be used for reflection of HF radar and communications signals. These discharges were created to analyse ionospheric phenomena and its impact on communications and space weather.Previous attempts by scientists to create electron density enhancements yielded densities of 4 x 105 electrons per cubic centimetre (cm3 the NRL group produced artificial plasma clouds with densities above 9 x 105 electrons cm3. The artificial plasma balls created in this study were seen to contain dynamically changing density structures. The electrons accelerated to high enough energy to produce the glow discharge in the neutral atmosphere, which was approaching altitudes of 170 kilometres. The acceleration of the electrons was thought to be due to electrostatic waves created by the HAARP radio transmissions.These artificial plasma clouds are detected using HF radio soundings and backscatter, ultrahigh frequency (UHF) radar backscatter, and optical imaging systems. Ground measurements of the stimulated electromagnetic emissions display the strength and frequency of the electrostatic waves that are responsible for the acceleration of the ambient electrons, which reach ionising velocities.The NRL team is aiming to develop a comprehensive theory of the plasma cloud generation.The image is a sequence showing the glow plasma discharge produced with transmissions at the third electron gyro harmonic using the HAARP HF transmitter, Gakona, Alaska. The third harmonic artificial glow plasma clouds were obtained with HAARP using transmissions at 4.34 megahertz (MHz). The resonant frequency yielded green line (557.7 nanometer emission) with HF on November 12, 2012, between the times of 02:26:15 to 02:26:45 GMT.-TELFor more on HAARP: http://on.fb.me/13Co4fGhttp://www.nrl.navy.mil/media/news-releases/2013/nrl-scientists-produce-densest-artificial-ionospheric-plasma-clouds-using-haarpPhoto: SRI International—Elizabeth Kendall -- source link
