本文报道了第一台用于介子层析成像的微型望远镜。该望远镜由四个，50×50平方厘米的电阻多路复用micromega组成，具有2D布局和基于Dream芯片的自触发电子设备。由于采用了多路复用技术，四个检测器可以通过一个前端单元读出。高电压由使用低功耗CAEN小型化模块的专用卡提供。纳米pc （Hummingboard）确保了高压控制和监测，加上温度反馈以及数据采集和存储。该仪器的总功耗仅为30瓦，即相当于一个标准灯泡。望远镜在室外运行了3.5个月，拍摄了美国航天局-萨克雷研究中心的水塔，其中包括1.5个月的太阳能电池板运动。自主开发的低功耗μ子望远镜具有前所未有的精度，在成像和μ子计量领域开辟了新的应用。
This paper reports about the first Micromegas-based telescope built for applications in muon tomography. The telescope consists of four, 50×50 cm2resistive multiplexed Micromegas with a 2D layout and a self-triggering electronics based on the Dream chip. Thanks to the multiplexing, the four detectors were readout with a single Front-End Unit. The high voltages were provided by a dedicated card using low consumption CAEN miniaturized modules. A nano-PC (Hummingboard) ensured the HV control and monitoring coupled with a temperature feedback as well as the data acquisition and storage. The overall consumption of the instrument yielded 30 W only, i.e. the equivalent of a standard bulb. The telescope was operated outside during 3.5 months to image the water tower of the CEA-Saclay research center, including a 1.5-month campaign with solar panels. The development of autonomous, low consumption muon telescopes with unprecedented accuracy opens new applications in imaging as well as in the field of muon metrology.
