Kitakyushu International Conference Center), Atomic Oxygen (AO) environment same as low earth orbit (LEO) is generated in chamber by dissociating molecular oxygen (O2) using pulsed CO2 of 5.5 Joule energy. The energy of the generated AO is controlled by primary molecular oxygen injection pressure, pulse duration of AO injection through pulse valve and delay time between laser and pulse valve opening signal. The velocity and energy of generated AO is measured by analyzing time of flight (TOF) signal detected by quadrupole mass analysis system (QMS). The velocity of AO at 2.0 MPa primary injection pressure, 550 micro second opening pulse duration for pulse valve and having a delay of 450 - 650 [micro second] is about 10.0 - 15.0 [km/s]. We are still manifesting above mentioned parameters to get a similar environment of LEO having 8 km/sec or 5 eV AO. The generated AO flux is 2.1 * 10(exp 18) [atoms/m2*s] and it is enough to experiment erosion test at LEO environment 1 year., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0064542026, レポート番号: JAXA-SP-09-006}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {原子状酸素照射装置開発を目的とした原子状酸素速度および流束の計測}, volume = {JAXA-SP-09-006}, year = {2010} }
