Download or read book Ion Mass Spectrometry of the Lower Ionosphere written by R. L. F. Boyd and published by . This book was released on 1974 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: A short pathlength radio frequency ion mass spectrometer was developed for rocket measurements in the D-and lower-E regions of the ionosphere without the interposition of a shock between plasma and spectrometer. Design and operation are discussed. Ions of mass 16 + or - 1, 18 + or - 1, 21 + or - 2, 28 + or - 2, 36 + or - 3 and 55 + or - 5 were detected on the ascent and descent between 90(+) and 120 km. The tentative ion identifications are O(+), H3O(+), Na(+), or Mg(+), NO(+), K(+) and Fe(+). (Modified author abstract).
