【摘要】：空間太陽望遠鏡(Space Solar Telescope,SST)主光學望遠鏡(Main Optical Telescope,MOT)口徑達1 m,以2.8′×1.5′有效視場對日成像,將獲得0.1″~0.15″的圖像。SST MOT對日觀測時所接收到的熱量超過千瓦,成為影響望遠鏡成像質(zhì)量的主要熱源和雜散光源。為此,文中首先探討了大口徑太陽望遠鏡熱設計與消雜光設計的特殊關聯(lián)。然后,針對主鏡筒內(nèi)消雜散光的內(nèi)遮光罩結構提出了熱兼容設計,確定了內(nèi)遮光罩結構熱-雜散光效應集成設計的目標與評價體系。借助熱分析軟件獲取SST MOT因內(nèi)遮光罩結構參數(shù)變化引起的系統(tǒng)溫度的變化趨勢,從熱控角度對內(nèi)遮光罩結構的設計提出了建議:內(nèi)遮光罩結構的垂直高度不宜超過400 mm。探索的內(nèi)遮光罩結構熱-雜散光效應集成分析方法也可為其他太陽望遠鏡的綜合優(yōu)化提供參考。
[Abstract]:Space Solar TelescopeSSTS (main Optical TelescopeSST) has a aperture of 1 m.The diurnal imaging with an effective field of view of 2.8'脳 1.5 'will result in an image of 0.1 "0. 15". The SST MOT will receive more than kW of heat when it observes the day. It has become the main heat source and stray light source affecting the imaging quality of telescope. For this reason, the special relationship between the thermal design of the large aperture solar telescope and the design of eliminating stray light is first discussed in this paper. Then, the thermal compatibility design of the inner light mask structure of the primary mirror tube is proposed, and the objective and evaluation system of the integrated design of the thermal stray light effect of the inner light mask structure are determined. With the help of the thermal analysis software, the change trend of the system temperature caused by the variation of the structure parameters of the SST MOT is obtained. From the point of view of thermal control, the design of the inner mask structure is suggested: the vertical height of the inner shade structure should not exceed 400mm. The integrated analysis method of the thermal and stray light effect of the inner shade structure can also be used as a reference for the integrated optimization of other solar telescopes.
