A system diagram and the circuit for each of the components of an automatic conductance plotting machine are presented. Conventional circuitry using vacuum tubes is used throughout. The circuit impresses a small 5‐kc incremental voltage of controlled amplitude upon the dc bias of the diode...
The theory and operation of a device that makes the beam in the Cosmotron come onto a target in about 5 μsec instead of the usual 3 msec are described. The magnetic field in a two‐turn coil, pulsed with a condenser bank, deflects the internal beam enough to throw the beam onto a target during...
A balance with a weighing range between 9 and 24 kg has been tested. The use of radiation resistant sensing devices makes it acceptable for use in hot cell applications. With an unrefined read‐out method the system sensitivity, including resolution of chart reading by eye, at 65% confidence...
The preparation of artificial β‐eucryptite (Li 2 O Al 2 O 3 2SiO 2 ) as a filament coating for the emission of Li + ions is discussed. Two ion sources with their initial focusing gaps are described.
The construction and operation of a molecular beam maser spectrometer, similar to the ammonia maser, is described. The observed linewidths are of the order of 5 kc at microwave frequencies, thereby allowing high resolution hyperfine spectroscopy on a number of molecules. The major factors...
