大毫米望远镜阿方索·塞拉诺(LMT)是一台直径50米的毫米波天文射电望远镜。在这篇文章中,我们描述了一些正在进行的升级天线系统和允许在白天进行科学观测的倡议。我们总结了最近的努力,以表征发生在LMT结构内的温度梯度,并确定重要的表面变形模式。缓解计划包括使用LMT的有效表面来抵消天线结构中测量的温度梯度的影响。它还包括积极的措施,如在天线后备结构中安装通风系统。展望了用于实时表面校正的天线表面的额外主动计量测量的前景。
The Large Millimeter Telescope Alfonso Serrano (LMT) is a 50m-diameter radio telescope for millimeter-wave astronomy. In this paper we describe a number of initiatives underway to upgrade the antenna systems and permit scientific observations during daylight hours. We summarize recent efforts to characterize the thermal gradients that occur within the LMT structure and to identify important modes of surface deformation. The mitigation program involves use of the LMT's active surface to counteract the effects of measured thermal gradients within the antenna structure. It also includes active measures such as the installation of a ventilation system in the antenna backup structure. Prospects for additional active metrology measurements of the antenna surface for real-time surface corrections are also discussed.
