Thus the new investigations gave the surprising result that the electrical charge within the proton is concentrated to smaller components of negligible size.
This unexpected discovery by the 1990 Laureates was noted immediately by certain skilled theoreticians, chiefly R.P. Feynman and J.D. Bjorken. The result was first interpreted within the framework of what is termed the parton model, which, however, soon came to be identified with the quark model. Very thorough analysis of the experimental results also gave the first hint of the existence of the neutral “glue particles”, later to be called gluons.
Large magnetic spectrometers were designed and built to achieve high quality in the measurements. Taylor directed the work on the mechanics and the magnets while Friedman and Kendall designed the detectors that were to record the scattered electrons after collisions in a target of liquid hydrogen or deuterium. The spectrometer arms are turned on rails around the target to select different angles.
