R & D of the Mobile Telescope Array Project for Very High Energy Cosmic Gamma-Ray Observations

“移动望远镜阵列”是一个可重定位成像大气切伦科夫望远镜的大规模阵列，并被提议作为未来的甚高能(VHE)伽马射线天文台。为了实现可再定位望远镜这一领域的新技术，人们进行了各种研究和开发。这样的望远镜应该独立于电源线，以便更容易地重新定位，并且只使用电池操作。为此，开发了一种低功耗数据采集系统，并对高容量电池进行了研究。为了在每次重定位后有效地校准望远镜姿态，还开发了一套利用GPS的自动校准系统。作为研发试验台的大气切伦科夫望远镜已经安装在东京大学宇宙线研究所秋野天文台，并将为未来VHE项目的各种研发进行维护。

The "Mobile Telescope Array" is a large-scale array of relocatable imaging atmospheric Cherenkov telescopes and proposed as a future Very High Energy (VHE) gamma-ray observatory. Various R & D have been carried out aiming to realize the relocatable telescope which is a new technology in this field. Such telescope should be independent of power cables for easier relocation and operated using only batteries. To this end, a low power consumption data acquisition system was developed and high capacity batteries were investigated. For calibrating telescope attitudes effectively after each relocation, an automatic calibration system utilizing GPS was also developed and estimated. An atmospheric Cherenkov telescope as a test bench for R & D has been located at the Akeno Observatory of the Institute for Cosmic Ray Research, the University of Tokyo, and will be maintained for various R & D of future VHE projects.
