- In mass spectrometry: Electronics
The operation of a mass spectrometer depends on elaborate electronic equipment: ion sources require extremely stable power supplies, magnets need instruments for measuring the magnetic field and controlling the current supply for the coils, detectors use a variety of power supplies and amplifiers, and…

- In materials science: Electronic materials
Between 1955 and 1990, improvements and innovations in semiconductor technology increased the performance and decreased the cost of electronic materials and devices by a factor of one million—an achievement unparalleled in the history of any technology. Along with this extraordinary explosion of technology…

…accrued from the application of electronics. Particularly significant was the perfection of the semiconductor thyristor, or “chopper,” control of current supply to motors. The thyristor—a rapid-action, high-power switch with which the “on” and “off” periods of each cycle can be fractionally varied—achieved smoothly graduated application of voltage to traction motors.…

Electronics have made a particularly important contribution to the load-hauling capability of diesel-electric locomotives in road freight work, by improving adhesion at starting or in grade-climbing. A locomotive accelerating from rest can develop from 33 to 50 percent more tractive force if its powered wheels…
