Summary
Upon completion of preliminary tests on the satisfactory operation of the Vibrating Reed Electrometer as a sensitive indication of alpha activity at the cathode of a plating cell, attention was directed toward the study of the detection of activity at the anode of the cell. Group 3 anticipates a lengthy study of cathodic and anodic deposition potentials of radioactive elements in solution. With the standard Research Plating Control, cathodic studies could be accomplished with relative ease, but the study of anodic deposition could only be done in an exploratory manner. This would provide meager information and lengthen the study considerably. To overcome the above objections, it was decided to modify the plating control so that it would provide linear control of the anode-solution potential. Study of the problem indicated that two simple changes were necessary; namely the reversal of current through the plating cell (since the anode instead of the cathode would be at ground potential) and the addition of a phase inverter in the amplifier circuit of the plating control to supply the control tube with a voltage change of the proper phase. Several tests made by Group 3 indicate that the use of the modified plating control will be satisfactory. Measurements of the three shielded rooms in the ``E`` Building have been completed. One scaler-multiplier EL-251, has been completed. First tests indicated that most of the scaling stages were scaling through when operated by the output of an Instrument Development Laboratory Model 162 scaler, apparently due to interstage coupling by way of the leads to the ``scale selector`` switch of the scaler. Work continues on the mechanical portion of the motor-driven slide wire. The gear box, providing three changes of speed (approximately 103, 1-9, and 1-27) worked well on the dry run test, but when loaded, would not operate.
