论文摘要

Marcot Pathfinder是西班牙喀拉尔语中音天文台(CAHA)的Marcot(多阵列望远镜)的先驱。 Marcot旨在提供Carmenes,目前从CAHA 350万望远镜中喂养纤维,并从数十台小型望远镜的电池中提供5-15m的光收集区域,这些望远镜的电池不连续地馈入光谱仪的最终关节单光纤进料。基于市售望远镜的模块化概念导致成本估算,这是极大望远镜(ELT)的成本估算。作为一种新颖的方法,Marcot将采用多模式光子灯笼(MM-PL)作为经典光子灯笼的变体开发,以将各个望远镜的光与单个光纤进料相结合到仪器。该进度报告介绍了Marcot的整体概念,在CAHA,MM-PL的概念以及安装Potsdam多路复用拉曼光谱仪(MRS)的下一步的CAHA概念的整体概念。 Marcot探路者将使用7个单元望远镜原型验证MM-PL在天空上的概念设计和预测性能。

MARCOT Pathfinder is a precursor for MARCOT (Multi Array of Combined Telescopes) at Calar Alto Observatory (CAHA) in Spain. MARCOT is intended to provide CARMENES, currently fiber-fed from the CAHA 3.5m Telescope, with a 5-15m light collecting area from a battery of several tens of small telescopes that are incoherently fed into the final joint single fiber feed of the spectrograph. The modular concept, based on commercially available telescopes, results in cost estimates that are a fraction of the ones for extremely large telescopes (ELT). As a novel approach, MARCOT will employ Multi-Mode Photonic Lanterns (MM-PL) that are being developed as a variant of classical photonic lanterns, to combine the light from the individual telescopes to a single fiber feed to the instrument. This progress report presents the overall concept of MARCOT, the pathfinder telescope and enclosure that is being commissioned at CAHA, the concept of MM-PL, and the next step of installing the Potsdam Multiplex Raman Spectrograph (MRS). MARCOT Pathfinder will be used to validate the conceptual design and predicted performance of MM-PL on sky with a 7 unit telescope prototype.
