项目摘要

We have developed a new-type electron detector(BETS) for balloon observations to resolve the acceleration mechanism of electrons in super nova. We have successfully carried out several balloon flights in Japan for measuring the electron energy spectrum from 10 GeV to a few hundred GeV. For measuring the electrons in TeV region, it is necessary to carry out a long term observation as 100 days, and we have tried to make a proposal for the NASA Research Announcement of Ultra Long Duration Ballooning(ULDB) in collaboration with NASA members. We have organized a Japan-US collaboration team for the common proposal, and we had some workshops both in Japan and US. The proposal was not accepted with a grade of "Very Good", and we are trying to be successful in next chance.As other opportunities of ULDB, we have a plan to do a long observation with a Polar Patrol Ballon(PPB) by National Institute of Polar Research in Japan and the trans-continental long duration ballooning between Brazil and Australia by Institute of Space and Astronautical Science(ISAS). Our ISAS members have visited Brazil for the planning. Both of them are very promising for balloon flights within a few years. As a future project, we are proposing a 3-year observation of electrons at Japanese Experiment Module/Exposure Facility on International Space Station. A collaboration plan for this was discussed between us and the US collaborators.We have also carried out developments of instruments at GERN by using the proton beams. As a result, it is proved the 64-anode PMT by Hamamatsu Photonics Co. Ltd has enough capability to detect a minimum ionizing particle for 1mm square scintillating fibers. We have, moreover, done simulation calculations for the detector design and theoretical studies on the relation between high-energy electrons and gamma-ray and for the diffusion characteristics of electrons in the Galaxy.
我们开发了一种用于气球观测的新型电子探测器(BETS),以解决超新星中电子的加速机制。我们已经在日本成功进行了几次气球飞行,测量了从 10 GeV 到几百 GeV 的电子能谱。为了测量TeV区域的电子,需要进行100天的长期观测,我们尝试与NASA成员合作为NASA研究公告超长持续时间气球(ULDB)提出建议。我们为共同提案组建了日美合作团队,并在日本和美国举办了一些研讨会。该提案没有被接受,评级为“非常好”,我们正在努力在下一次机会中取得成功。作为 ULDB 的其他机会,我们计划使用日本国立极地研究所的极地巡逻气球(PPB)进行长期观测,以及空间与宇航科学研究所(ISAS)在巴西和澳大利亚之间进行跨大陆长时间热气球观测。我们的 ISAS 成员已访问巴西进行规划。两者都非常有希望在几年内实现气球飞行。作为未来的项目,我们提议在国际空间站的日本实验舱/曝光设施中进行为期 3 年的电子观测。我们和美国合作者讨论了这方面的合作计划。我们还在 GERN 利用质子束进行了仪器的开发。结果证明,Hamamatsu Photonics Co. Ltd 的 64 阳极 PMT 具有足够的能力来检测 1mm 方形闪烁纤维的最小电离粒子。此外,我们还对探测器设计进行了模拟计算,对高能电子与伽马射线的关系以及电子在银河系中的扩散特性进行了理论研究。
