摘要:

4.1米SOAR望远镜的自适应模块SAM使用紫外激光引导星校正地面层湍流。它于2013年投入使用,自2014年以来一直在正常的科学运作中。SAM与覆盖3'场的CCD成像器或散斑相机一起工作。它的工作常规和稳定,提供等于自由大气视宁度的I波段分辨率。本文介绍了SAM系统作为一个整体,其用户和仪器感兴趣的技术信息提供必要的参考。本文介绍了该仪器的工作原理、性能特点以及迄今为止用SAM进行的科学研究项目。

英文摘要:

The adaptive module of the 4.1-m SOAR telescope, SAM, corrects ground-layer turbulence using a UV laser guide star. It has been commissioned in 2013 and it is in regular science operation since 2014. SAM works with the CCD imager covering a 3' field or with the speckle camera. It operates routinely and stably, delivering resolution in the I band equal to the free-atmosphere seeing. This paper describes the SAM system as a whole, providing essential reference for its users and technical information of interest to instrumentalists. Operation of the instrument, its performance, and science projects done with SAM so far are reviewed.
