The technique called "imaging atmospheric Cherenkov telescope" is established recently. This technique aims at the detection of sub-TeV gamma-rays from astronomical objects. The CANGAROO telescope is one of big-four telescopes in the world. those telescopes usually located in hard place such as desert. In the experimental cite of CANGAROO, the available infra structures are only AC and telephone line. the lack of the high-speed network, for example ADSL, is critical for these experiments.Due to the above, we are now forced to send four scientists each month for observation. One scientist is needed to operate one telescope, here we are operating four telescopes (stereoscopic observation mode). The automation and IT for the instruments are key to solve this. In this study, we developed a automatic shutter which can be operated wireless from the control center. Also VME modules to control threshold, calibration light source, and etc. were made and installed. Also we investigated a possibility to use Woomera (a village, 10km away from the experimental cite). We estimated a cost of microwave system to transfer these network from Woomera to the experimental cite. From now on, rather political action is necessary between Australia and Japan. The high-speed network is really necessary to maintain these telescopes.

最近建立了一种称为“成像大气切伦科夫望远镜”的技术。该技术旨在检测来自天体的亚TeV伽马射线。 CANGAROO望远镜是世界四大望远镜之一。这些望远镜通常位于沙漠等坚硬的地方。在CANGAROO实验基地，可用的基础设施只有交流电和电话线。缺乏高速网络，例如ADSL，对于这些实验至关重要。由于上述原因，我们现在被迫每月派出四名科学家进行观察。需要一名科学家操作一台望远镜，这里我们操作四台望远镜（立体观测模式）。仪器的自动化和信息技术是解决这个问题的关键。在这项研究中，我们开发了一种可以从控制中心无线操作的自动快门。还制作并安装了控制阈值、校准光源等VME模块。我们还调查了使用 Woomera（距离实验基地 10 公里的一个村庄）的可能性。我们估算了将这些网络从伍默拉转移到实验地点的微波系统的成本。从现在开始，澳大利亚和日本之间有必要采取政治行动。高速网络对于维护这些望远镜确实是必要的。
