Ron Val leaped past Hargraves, dived for a seat on the negatron.
Ron Val lifted a white face from the sighting 'scope of the negatron.
The negatron swung around to the right, centered on something there.
"If they don't succeed in manning the negatron," Usher pointed out.

- An electron with a negative charge; the antiparticle of the positron. Most branches of particle physics construe each particle along with its antiparticle to be two different forms of one underlying phenomenon, and the term electron is sometimes used as a precisely such a general term, with positron and negatron referring to the forms of the electron as they are manifested in nature. See more at electron.
- A stable elementary particle in the lepton family having a mass at rest of 9.107 X 10-28 grams and a negative electric charge of approximately 1.602 X 10-19 coulombs. Electrons orbit about the positively charged nuclei of atoms in distinct orbitals of different energy levels, called shells. Electrons are the primary charge carriers in electric current. Compare positron. See also electromagnetism elementary particle ion. See Table at subatomic particle.
- A positron or a negatron.
