Abstract:

All of the necessary equipment has been constructed to complete the absorption measurements with a ruby beam in air samples from 6942 - 6943 A. Preliminary experiments with a piezo-electric ceramic microphone indicate that the sensitivity and bandwidth of this type of microphone is inadequate to detect the H2O band at 6942.15 A. It confirms the fact that there is no anomalously large absorption, and that the sensitivity of the collodion membrane microphone will be required. All of the subsystems of the experiment were successfully operated separately and all but the new force-balance collodion microphone were operated together. Work during the past quarter on these subsystems is described. Author
