Equipment and supplies are being packed for moving to Mound Laboratory. Work was started on the development of a cathode-follower circuit to match a B-wall tube to its connecting cable. The final report and maintenance manual for the scaler-multiplier are almost finished. The 10 millivolt Speedomax recorder used by Group 3 in the study of electrodeposition potentials has been replaced with a 150 millivolt Speedomax, utilizing two recording points for simultaneous recording of radioactive deposition and the plating cell current. Three two-input B-wall mixers, three scaler-multipliers, one four-input Geiger-Mueller mixer and five Thyratron heater controls were delivered to Group 24. One high-current plating control, EL-173, was delivered to Group 17. The following instruments are complete: portable pulse generator, EL-261, the instruction book and photographs will be submitted for approval at an early date. Portable regulation checker, EL-258. Preliminary tests have been made, instructions are being written and drawings are being made
