This project will provide an X-ray camera and a germanium spectrometer to study MeV X-ray bursts at very high latitudes. The instrument will be flown on a long-duration balloon flight that is being funded by NASA. This is a reflight of an experiment that was originally flown in 1998. The original experiment was funded in part by NASA and in part by NSF under grant ATM-9806400. That experiment failed because of a failure of the balloon. The original instruments were badly damaged or destroyed in the failure. This project will refurbish and rebuild the necessary components for a new flight. The flight duration is expected to be about two weeks. The first detection of terrestrial X-ray bursts with energies extending up to the MeV range was made in 1996. This experiment will be able to examine the temporal evolution of these high energy bursts, which will help elucidate the mechanism that produces the bursts.

该项目将提供一台X射线照相机和一台锗光谱仪，用于研究极高纬度兆电子伏的X射线爆发。 该仪器将在美国宇航局资助的长期气球飞行中飞行。 这是1998年首次飞行的一个实验的重现。 最初的实验部分由NASA资助，部分由NSF资助ATM-9806400。 由于气球故障，该实验失败了。 原来的仪器在故障中严重损坏或毁坏。 该项目将为新的航班重新组装和重建必要的部件。 预计飞行时间约为两周。 1996年首次探测到能量高达MeV的地面X射线爆发。 这个实验将能够检查这些高能量爆发的时间演化，这将有助于阐明产生爆发的机制。
