Allowable temperature rise in tubes of the piles: Precautions against boiling
In the design of the pile, it was considered advisable never to impose so great a heat load on any tube that the available header pressure would be insufficient to sweep the tube free of vapor if boiling should accidentally be initiated in the tube. Figures are given for the maximum temperature rises permissible, as function of header pressure and orifice diameter.

Beta M2 Slit Support
A new G slit support utilizing the standard G carbon now in use in all Beta production buildings was tested over approximately four months in the Pilot Plant with very successful results. A considerable saving has been made both in servicing time and in costs. The equipment has proved to be the best of any tried from the standpoint of run terminations due to alignment difficulties.

The Average Q Meter
The average Q meter is an instrument which averages the Q over over short periods of time, thus taking into account non-productive moments due to sparking and other factors, giving a truer measure of production than the present instantaneous meters. Embodied in this report are its methods of operation, reasons for its use, and descriptions of various physical types of the average Q meter.

Monsanto Chemical Company, Unit 3 abstracts of progress reports, August 16--31, 1945: Summary of work to date on volatile neutron source
It was proposed to prepare a volatile polonium compound which could be used alone or with another gaseous compound as a neutron source. The objective was to obtain a neutron source which would give off few neutrons in the expanded state, but when condensed would act substantially as a thick target and emit perhaps ten times as many neutrons. Originally, polonium hexafluoride was suggested; with such compound the fluorine atoms would constitute the target. the predicted boiling point of polonium hexafluoride is about -40 {degrees}C. There was reason to believe, however, that lower relatively non-volatile fluorides would be formed rather than the hexafluoride. Polonium alkyls were therefore proposed as alternatives. The predicted boiling point of Po(CH{sub 3}){sub 2} is about 110 {degrees}C. This compound in itself would probably not be suitable as a target material but it could be mixed with other gases such as carbon tetrafluoride, boron trifluoride, etc., as targets. As a longer range possibility, Po(CF{sub 3}){sub 2} was also suggested. This compound would act as its own target and would moreover have the same F/Po ratio as PoF{sub 6}; its boiling point could be expected to be 30{degrees} - 60 {degrees} lower than that of polonium dimethyl. …
