摘要:

介绍了星载大孔径亚毫米波偏振望远镜(BLASTPol)的热模型。该仪器于2010年和2012年在南极洲麦克默多成功进行了两次绕极飞行。在这两次飞行中,BLASTPol通过测量星际尘埃颗粒的偏振热发射,获得了有关分子云中磁场的前所未有的信息。实验的热设计解决了这种测量所需的有效载荷的稳定性和控制问题。我们描述了热建模的有效载荷,包括太阳屏蔽策略。我们提出的仪器在飞行中的热性能,并比较模型的预测与飞行过程中登记的温度。我们描述的困难建模的热行为的气球载平台,并建立地标,可用于未来的气球载仪器的设计。

英文摘要:

We present the thermal model of the Balloon-borne Large-Aperture Submillimeter Telescope for Polarimetry (BLASTPol). This instrument was successfully flown in two circumpolar flights from McMurdo, Antarctica in 2010 and 2012. During these two flights, BLASTPol obtained unprecedented information about the magnetic field in molecular clouds through the measurement of the polarized thermal emission of interstellar dust grains. The thermal design of the experiment addresses the stability and control of the payload necessary for this kind of measurement. We describe the thermal modeling of the payload including the sun-shielding strategy. We present the in-flight thermal performance of the instrument and compare the predictions of the model with the temperatures registered during the flight. We describe the difficulties of modeling the thermal behavior of the balloon-borne platform and establish landmarks that can be used in the design of future balloon-borne instruments.
