Cerenkov x-ray emissions should not exist in media where the index of refraction is less than unity. In previous work, x-ray Cerenkov radiation at the K absorption edge of aluminum was reported to have been observed. The present experiment observed no x-ray Cerenkov radiation. However, radiation not characteristic of the Cerenkov mechanism was seen. The results of the experiment are provided. Various aspects of an experiment designed to investigate Cerenkov radiation in the x-ray region are also considered by exploring procedures, methods, equipment design and limitations. Suggestions for improvements to facilitate further experiments with media that allow the formation of Cerenkov radiation are provided.
