AST-9619186 Submillimeter Polarimetry. Instrumentation recently developed by Dr. Roger Hildebrand at the University of Chicago has made it possible to observe the polarization of the submillimeter wavelength emission from interstellar clouds at more points and with better precision and spatial resolution than has been possible before. Dr. Hildebrand will now exploit this capability by using the instrumentation at the California Institute of Technology Submillimeter Observatory in Hawaii to make maps of polarization in several types of interstellar clouds. The primary goal is to infer the shapes of the magnetic fields in these objects. A secondary goal is to investigate the mechanism that aligns the dust grains responsible for the polarized emission. ==============================

AST-9619186亚毫米偏振法。芝加哥大学的罗杰·希尔德布兰德博士最近开发的仪器使人们能够在更多的点上观察到星际云发射的亚毫米波长的偏振，并且比以前具有更高的精度和空间分辨率。希尔德布兰德博士现在将利用位于夏威夷的加州理工学院亚毫米天文台的仪器来绘制几种星际云的偏振图。主要目标是推断出这些物体磁场的形状。第二个目标是研究导致偏振辐射的尘埃颗粒排列的机制。==============================
