康普顿成像望远镜COMPTEL是康普顿伽玛射线天文台(GRO)上的四台仪器之一，康普顿伽马射线天文台于1991年4月5日由亚特兰蒂斯号航天飞机发射进入450公里高度的地球轨道。COMPTEL正在探索1-30 MeV的能量范围，角分辨率(1σ)在约1立方的大视野内介于1°和2°之间。它的能量分辨率(1.27 MeV时半高宽为8.8%)使其成为一台功能强大的伽马射线线谱仪。它的有效面积(轴上入射)根据能量和事件选择的不同在10到50 cm2之间变化。在14天的观察期内，COMPTEL能够探测到比螃蟹弱20倍的震源。COMPTEL的测量原理也允许测量太阳中子
The imaging Compton telescope COMPTEL is one of the four instruments on board the Compton Gamma-Ray Observatory (GRO), which was launched on 1991 April 5 by the space shuttle Atlantis into an Earth orbit of 450 km altitude. COMPTEL is exploring the 1-30 MeV energy range with an angular resolution (1σ) between 1° and 2° within a large field of view of about 1 steradian. Its energy resolution (8.8% FWHM at 1.27 MeV) makes it a powerful gamma-ray line spectrometer. Its effective area (for on-axis incidence) varies between 10 and 50 cm 2 depending on energy and event selections. Within a 14 day observation period COMPTEL is able to detect sources which are about 20 times weaker than the Crab. The measurement principle of COMPTEL also allows the measurements of solar neutrons
