The lines of force representing this field radiate outward from a positive charge and converge inward toward a negative
charge. The composite field of several charges is the vector sum of the individual fields. In this Demonstration, you
can move the three charges, shown as small circles, and vary their electric charges to generate a stream plot of the
She says ION was going to field

The cyclotron was invented in 1932 by Ernest O. Lawrence and M. S. Livingston at Berkeley. Particles or ions are
injected into the center of two hollow D-shaped objects called "dees." A magnetic field is applied to them that is
perpendicular to the plane in which they move and they accelerate across a gap between the dees by a potential
difference. The orbit radius increases and eventually the particles gain energy and are ejected to hit a target. It is
one of the earliest types of accelerators in use today.
Some sort of laser.
A laser-induced plasma channel. It
creates a channel in the air that
allows the system to fire a bolt of
electricity along it.
This Demonstration considers the intensity distribution of Hermite-Gaussian transverse
electromagnetic (TEM) modes produced by a laser. These modes are solutions of the paraxial wave equation in Cartesian coordinates.
