SUMMARY:Plasma Surface Interactions and Accelerated Life Testing – The Ke
 y Technology Challenges in the Development of Gridded Ion Engines
DESCRIPTION:Lecturer:Prof. Stephen Gabriel\n Faculty:Department of Aeronaut
 ics and Astronautics\n Institute:University of Southampton\, Southampton\,
  UK and Mars Space Ltd\, UK\n Location:Asher Space Research Institute (ASR
 I) seminar room\n Zoom: \n Abstract: \n Details: \n The talk will present 
 an overview of the research activities on Electric Propulsion (EP) and oth
 er low temperature plasma technologies at both the university of Southampt
 on and Mars Space Ltd\, focusing on some of the key challenges.\nThe unive
 rsity has been active in EP for nearly 30 years\, while Mars Space was spa
 wned as a spin-off around 10 years ago. How the two organizations have col
 laborated as partners will be described with an attempt to bring out some 
 of the successes but also some of the potential problems.\nHistorically\, 
 EP research at the university has included gridded ion engines(GIEs)\, hol
 low cathodes(HCs) and hollow cathode thrusters(HCTs)\, pulsed plasma thrus
 ters(PPTs) and microcolloid thrusters. Current activities are centred arou
 nd heaterless hollow cathodes\, alternative propellants for GIEs and liqui
 d PPTs. Some of the terrestrial applications of low temperature plasmas wh
 ere there is some synergy with EP are plasma antennas and triggered vacuum
  arcs.\nAt Mars Space\, the main research areas are broadly similar but mo
 re of a developmental nature and in close collaboration with industry. Key
  areas include the development of a ring cusp(RC) GIE with QinetiQ and a G
 IE hollow cathode neutralizer with Ariane Group but work is also ongoing o
 n a high temperature resistojet with the possibility of future efforts on 
 an arcjet with Nammo.
