Electronics progress report, April 1--30, 1949
Prospectus` of Band Pass Amplifiers for Proportional Counters and Instrumentation for the Study of the Electrodeposition Potential of Radioactive Elements have been submitted for review and approval. An error was found in calculations for the band pass amplifier discussed in Group 9 of the Electronics Progress Report,MLM-306, March 1--31, 1949, on the Cathode-Follower Probe. New calculations have been made and a band pass filter constructed to match the new values. Work on the cathode-follower circuit for coupling a Boron-wall tube to its linear amplifier indicated that the limit to the sharpness of a pulse which could be achieved was possibly caused by poor amplitude versus frequency response of the linear amplifier. To check this theory, modifications were made on an existing scaler which resulted in a frequency response flat up to 4.5 megacycles. Plans are being made to improve the amplitude versus frequency of the higher frequencies. The response curve shows a slightly rising characteristic at 4.5 megacycles and an attenuation at 7 megacycles. Construction of the rf generator has been resumed in an effort to deliver the finished product to Group 4 by approximately May 6, 1949. The meter circuit will measure relative rf output voltage instead of absolute …

Electronics progress report, March 1--31, 1949
With the completion of tests of the prototype cathode-follower, it was decided to produce three more models. These have been constructed and pass the same pulse as that of the prototype. Drawings are being made of these units. By the time these units had been completed, the amplifier of the scaler was modified so that its frequency response was essentially flat up to 4.5 megacycles. Using this amplifier and the cathode-follower, a study of the pulse shapes was made and four different pulse shapes were found to be obtainable. A band pass network between the B-wall tube and the input of the cathode-follower provided a very substantial improvement over the shunt peaking network with a band pass of 1.8 to 6.5 megacycles and provided clean, uniform pulses. Plans are being made to experiment with a filter of narrower band pass, which, if satisfactory, will produce greater amplitude. When the final band pass has been determined, a combination of shunt peaking and band pass networks should provide a net gain of 30% in amplitude. The result of this research is to provide an immediate improvement in resolution loss and a possibility of realizing a still lower minimum resolving time when the …

Instrumental analysis progress report, June 1--30, 1949
Several bismuth compounds have been submitted by E. Orban for examination by x-ray diffraction. The sample of polonium in contact with platinum mentioned in the May progress report was received and identified tentatively from its x-ray diffraction pattern as PtPo{sub 2}. Calibration of the Perkin-Elmer infrared spectrophotometer has been completed and a preliminary study of the infrared absorption of NiCO{sub 4} made. Data showing the spectral purity obtainable on three ultraviolet-visible spectrophotometers have been completed. The emission spectrum of a sample of volatile impurity from the operations process has been obtained.

Production research progress report, March 1--31, 1949
A study has been made of the time and temperature required to anneal Teflon and Fluorothene. It has been found that, by proper annealing, the strains my be removed and cold-flow prevented. The disk stopcocks prepared with annealed plastics have not developed leaks on standing. A description is given of the modified slug-dissolver heating unit which has been installed in the Bismuth-II Process Line. Work has been continued on the absorption spectra of bismuth in hydrochloric acid solutions. Two methods have been described for the interpretation of absorption spectra data. The transmission curve of the Evelyn colorimeter filters have been measured on the Cary recording spectrophotometer. The resulting curves should aid in the selection of the proper filter for a given calorimetric analyses. A brief outline for the proposed method of decontaminating platinum has been presented.

Recovery of uranium and plutonium from Redox off-standard aqueous waste streams
In the operation of countercurrent extraction columns as in the Redox process, it is possible, and probable, that from unexpected behaviour of a column, operator error, colloid formation, etc., there will result from time to time excessive losses of uranium and plutonium in the overall process. These losses will naturally accumulate in the waste streams, particularly in the aqueous waste streams. If the loss is excessively high, and such lost material can be recovered by some additional method, then if economical and within reason, the recovered materials ran be returned to a ISF column for further processing. The objective of this work has been to develop such a method to recover uranium and plutonium from such off-standard waste streams in a form whereby the uranium send plutonium can be returned to the process line and subsequently purified and separated.
