Abstract

RUNJOBは、1次宇宙線の化学組成とエネルギーの測定を目的として、1995年より日本ロシアの共同研究として始まった。現在まで4回の気球キャンペーンを行い、11機の気球の放球を行い、10機で観測の成功を収めた。解析もほぼ終了の時期に近づいている。この段階で、これまでの共同研究を振り返り、特徴的なことや課題などを考えてみる。ここに示すことは、共同研究全体の意見をまとめたものではなく、個人的な意見や評価が含まれていることを前もって申し上げておく。, RUssia-Nippon JOint Balloon experiment (RUNJOB) started in 1995 to measure the chemical compositions and energy spectra of the primary cosmic rays. There were 4 balloon campaigns till 1999 and 11 balloons were launched, out of which 10 balloons were successfully recovered with more than 130 hour flight time. This collaboration is very close to the end and the experiment will be summarized and some problems will be pointed out. This report does not represent the opinions of the collaboration but includes the personal views of the author., 資料番号: AA0048133008, レポート番号: JAXA-RR-04-015
