The Spectrochemical Analysis of Hafnium and Zirconium
Abstract: "The analysis of hafnium and zirconium by the copper spark technique is presented for solutions of HCl, HF, and HClO4 acids. The special techniques of electrode protection and vacuum drying of perchloric acid samples are outlined. Also given are the working curves and deviations of both elements."

Use of the Characteristics of Permalloy in Detecting a Predetermined Value of Magnetic Field or Current in a Time-Varying Electromagnet: 1/4 Scale Bevatron Operating Model, Magnetic Field Strength-Magnet Current Correspondence
In programming the sequence of events in the operational cycle of the bevatron, certain devices must be triggered at specific values of magnetic field strength in the gap. It is desirable that the time-jitter, which corresponds to field jitter, of the tirggering pulses be small. In the synchrotron this is done with peaking strips which are located in the fringing field of the gap.
