为了寻找来自宇宙点源的VHEγ射线发射，目前在加那利亚的拉帕尔马岛上建立了一个切伦科夫望远镜成像系统；第一台望远镜自1992年起投入使用。空气簇射粒子的切伦科夫光被一个5平方米的反射镜收集。焦点上的相机包含37个光电倍增管，对切伦科夫闪光的图像进行采样。随后的图像分析允许区分γ射线诱导的事件和更丰富的带电宇宙线诱导的簇射。该望远镜对γ流星雨的有效能量阈值约为1.5TeV。在运行的第一年，探测到了来自蟹状星云的信号。
In search of VHE γ ray emission from cosmic point sources a system of imaging Cherenkov telescopes is constructed at present on the Canarian island of La Palma; the first telescope has been operational since 1992. The Cherenkov light from air shower particles is collected by a 5 m2reflector. The camera at the focus contains 37 photomultipliers which sample the images of the Cherenkov flashes. The subsequent image analysis allows the discrimination of γ ray induced events from the much more abundant charged cosmic ray induced showers. The telescope has an effective energy threshold for γ showers of about 1.5 TeV. During the first year of operation a signal from the Crab nebula was detected.
