This grant is to support the high resolution measurement of x and gamma rays from both the sun and supernova 1987a on two balloons which are to be launched from South Pole Station during the austral summer of 1989-1990. The work has several goals: 1) To study nucleosynthesis in the supernova. 2) To study electron and ion acceleration processes in solar flares. 3) To search for cosmic gamma ray bursts, cyclotron radiation and gravitationally red-shifted position annihilation lines. The detectors are large, liquid nitrogen cooled, segmented germanium crystals. They are actively shielded, and will provide high resolution measurements from 15 keV to several MeV. The balloon flights are expected to last for 5-20 days. It is hoped, but not required that the payloads can be recovered. This proposal is a precursor to the solar flare studies that are expected to be proposed as part of the MAX '91 campaign.

这项拨款是为了支持高分辨率的测量x和 来自太阳和超新星1987 a的伽马射线在两个气球上 这些卫星将于2008年12月25日至26日期间从南极站发射。 1989年至1990年夏季。 这项工作有几个目标： 1)研究超新星的核合成。 2)研究太阳能中电子和离子的加速过程 照明弹 3)为了寻找宇宙伽马射线爆发，回旋辐射和 引力红移位置湮灭线。 探测器是大型的，液氮冷却，分段的 锗晶体 它们被积极地屏蔽了， 从15 keV到几MeV的高分辨率测量。 的 气球飞行预计持续5-20天。 希望， 但不要求可以恢复有效载荷。 这 该提案是太阳耀斑研究的先驱， 预计将作为MAX '91活动的一部分提出。
