SUMMARY:New Propellants for Ion Thrusters – Iodine and Other Alternatives
DESCRIPTION:Lecturer:Dr. Kristof Holste\n Faculty:Institute of Experimental
  Physics I\n Institute:Justus-Liebig-University of Giessen\, Germany\n Loc
 ation:Classroom 165\, ground floor\, Library\, Aerospace Eng.\n Zoom: \n A
 bstract: \n Details: \n Ion thrusters are nowadays routinely used on satel
 lites for attitude control and for dedicated space missions\, such as GOCE
  and Dawn. The commonly used propellant for ion thrusters is the noble-gas
  xenon\, which comprise some advantages such as high atomic mass\, no chem
 ical reactivity\, and efficient ionization. One disadvantage of xenon is t
 he high price\, which leads to high costs for testing and qualification of
  thrusters. Potential candidates for alternative propellants are currently
  under investigation in the electric propulsion community. An interesting 
 material is iodine\, which has a high mass\, a high ionization efficiency 
 and a high density due to its solid nature at standard temperature. It can
  be evaporated with moderate heating power and was successfully tested rec
 ently at Giessen university with a radiofrequency ion thruster. The talk w
 ill present performance results of iodine and gives an overview about alte
 rnative propellants in general.
