在各种物体中，很明显非热过程在高能物体中发挥着重要作用。它们在超过 10 keV 时表现出色，其总能量可与热元件相媲美。为了检查这种非热过程，我们提出了硬X射线成像任务NeXT（新X射线望远镜任务）以及软伽马射线探测器和高分辨率光谱仪。硬 X 射线望远镜由多层镀膜高通量反射镜组成。焦平面探测器是混合型成像探测器，可覆盖软 X 射线和硬 X 射线。点源灵敏度的总体性能比当前计划的 10 - 60(80) keV 范围内的任何任务都要好 100 倍，而软伽马射线的灵敏度要好 10 倍。计划于 2011 年推出。
In various objects, it has been evident that non-thermal processes are playing important roles in high energy objects. They become outstanding above 10 keV and its total energy could be comparable to that of thermal components. In order to examine such non-thermal processes, we propose a hard X-ray imaging mission NeXT (New X-ray Telescope mission) together with the soft gamma ray detector and the high resolution spectrometer. Hard X-ray telescopes consist of multilayer coated high through put mirrors. The focal plane detectors are hybrid type imaging detectors to cover both soft and hard X-rays. Total performance in sensitivity for a point source reaches 100 times better than any currently scheduled missions in 10 - 60(80) keV range and 10 times better in soft gamma rays. It is planned to launch it in the time frame of 2011.
