Abstract HILDEBRAND, R. H. AST-9614886 Funds will be used for a series of improvements to the University of Chicago polarimeter, Hertz, which should greatly extend the range of objects that can be investigated. An undersized filter is to be replaced, anti- reflection coatings are to be installed, an inefficient polarizing beam splitter is to be replaced, and provision is to be made for operation of the detector at a lower temperature. New, high-responsivity detectors are also to be tested and a continuously rotating half-wave plate will be developed to permit new modes of operation.

HILDEBRAND, r.h. st -9614886基金将用于芝加哥大学赫兹偏振计的一系列改进，这将大大扩展可研究对象的范围。要更换尺寸过小的滤光片，安装防反射涂层，更换效率低下的偏振分束器，并为探测器在较低温度下的工作做好准备。新的高响应探测器也将进行测试，并将开发一个连续旋转的半波板，以允许新的操作模式。
