Abstract

気球搭載型超伝導サブミリ波リム放射サウンダ(BSMILES: Balloon-borne Superconducting SubMIllimeter-wave Limb-Emission Sounder)は、成層圏中の微量分子を観測する有用な装置である。2006年9月4日、成層圏中のHO2の日変化の観測することを目的に、BSMILESによる第3回目の放球実験が行われた。BSMILESには直径300mmのオフセットパラボラアンテナ、液体ヘリウム冷却の630GHz帯超伝導受信機、音響光学型分光計、3軸光ファイバジャイロなどが搭載されている。BSMILESはB200型気球により放球され、高度約37.9kmにおいてオゾンや微量分子の観測を行い、観測終了後海上回収された。<br />A Balloon-borne Superconducting SubMIllimeter-wave Limb-Emission Sounder (BSMILES) is powerful tool for observations of stratospheric minor constituents. The third flight experiment of BSMILES was conducted on September 4, 2006 to observe diurnal variation of HO2. BSMILES carries an offset parabolic maim reflector with a diameter of 300 mm, a 630 GHz-band SIS (Semiconductor Insulator Semiconductor) mixer cooled by liquid helium, an acousto-optical spectrometer, and three-axes fiber-optic gyroscope. The gondola was lifted to an altitude of about 37.9 km by a balloon of 200,000 cu m in volume. The system operated properly and emission line spectra of O3 and minor constituents were measured. The system was retrieved from the sea after the observation.<br />資料番号: AA0063732004<br />レポート番号: JAXA-RR-07-009
