Experimental Data on Pumping of Mercury Ion Beams by Liquid-nitrogen-cooled Condensers
Author: Edward A. Maslowski
Publisher:
ISBN:
Category : Mercury
Languages : en
Pages : 20
Book Description
A program was conducted to evaluate the performance of liquid-nitrogen-cooled condensers in pumping the exhaust of mercury ion thrustors. Tests were conducted with two different condensers. One of the condensers was a smooth cylinder having a total surface area of 3. 8 square meters, and the other condenser was of honeycomb type of construction and had a total surface area of 62. 9 square meters. Two targets, having apex angles of 320 and 1480, respectively, were used with each condenser. Ion beam current ranged from 10 to 200 milliamperes and accelerating potential from 2. 0 to 6. 0 kilovolts. The results were evaluated on the basis of a performance factor F̂ which is a function of the condenser accommodation and sticking coefficients. A mean value of F̂ of 0. 75 was determined in this study. A visual observation of mercury distribution patterns showed that the ratio of effective pumping area to actual geometric area was 0. 4 for the smooth condenser and 0. 1 for the honeycomb condenser. This study showed no significant difference in the effect of the two targets.

ISBN:
Category : Science
Languages : en
Pages : 313
Book Description
"Nitrogen: From Discovery to Modern Energy Applications" is an in-depth exploration of one of the most vital and versatile elements in the natural world—nitrogen. This comprehensive guide delves into the discovery, chemistry, and evolving applications of nitrogen, highlighting its transformative role in agriculture, energy systems, industry, and sustainability. From its essential use in fertilizer production to its emerging significance in the hydrogen economy and clean energy solutions, nitrogen is at the forefront of technological innovations that are reshaping industries. This book provides a detailed look into nitrogen’s chemical properties, the processes for its production, and how it is being leveraged to address global challenges such as food security, climate change, and energy sustainability. The book traces nitrogen’s journey from early scientific discoveries to its modern-day applications in fields such as: Materials science, where nitrogen-doped materials are revolutionizing electronics and energy storage. Agriculture, where advanced nitrogen fertilizers are boosting crop yields while reducing environmental impact. Energy, where green ammonia is emerging as a key hydrogen carrier for the clean energy transition. Environmental management, with technologies that reduce nitrogen pollution and promote sustainability. Written by Ron Legarski, President and CEO of SolveForce, this book draws on over two decades of experience in telecommunications, IT infrastructure, and emerging technologies. Legarski combines his expertise in connectivity solutions with a deep understanding of nitrogen’s pivotal role in modern industries, offering readers a unique perspective on how nitrogen is driving innovation in today’s interconnected world. Whether you're a scientist, engineer, business leader, or environmental advocate, this book provides valuable insights into the role of nitrogen in building a more sustainable and efficient future. With detailed case studies, technological innovations, and forward-looking analysis, "Nitrogen: From Discovery to Modern Energy Applications" is an essential resource for anyone interested in the intersection of science, technology, and sustainability.
