| Summary: | An infra-red telescope, capable of detecting
signals of the order of 10⁻⁶ watts incident on the
mirror, has been built. RCA acorn type pentodes
954 and 956 have been examined as electrometer tubes
in the region of grid current of 10⁻¹² amperes. It is indicated, on the basis of the small sample used, that the 954 is the better tube for this purpose. === Science, Faculty of === Physics and Astronomy, Department of === Graduate |
