We present briefly the LLAMA sub-mm radiotelescope, a joint project of Argentina and Brazil, being mounted in the Andes, Argentina, at 4800 m altitude. Here we focus on the activities that are going on mostly under the responsibility of Brazil, like the high frequency receivers, parts of the back-end and electronics, the optical system of the telescope to bring the radiation to the receivers, the equipment needed for the integration and verification phase (optical telescope and holography) and the computation system.The main scientific applications that are planned are dscribed. We also report on a joint program with BRICS countries approved in 2019, which will involve the use of LLAMA for testing high-frequency receivers.
我们简要介绍了 LLAMA 亚毫米波射电望远镜，这是阿根廷和巴西的联合项目，位于阿根廷安第斯山脉，海拔 4800 米。这里我们主要介绍由巴西负责的活动，如高频接收器、后端和电子设备的一部分、将辐射传输到接收器的望远镜光学系统、集成和验证阶段所需的设备（光学望远镜和全息术）以及计算系统。我们还介绍了 2019 年批准的与金砖国家的联合计划，该计划将涉及使用 LLAMA 测试高频接收器。
