My first project was to build an ionization gauge control circuit for Professor Edgar Everhart's Cockcroft-Walton accelerator. In those days, vacuum tubes were the active components in electronic circuits. I can still recall the warm orange glow of the vacuum tube filaments and the cool blue glow of the thyratron tubes.

Measurements of the specific ionization of both the positive and negative particles, by counting the number of droplets per unit length along the tracks, showed the great majority of both the positive and negative particles to possess unit electric charge.

Simultaneous recording with superimposed ionization chambers and Wilson chambers, ionization chambers and sets of counting tubes, has not yet been carried out.

The removal of an electron from the surface of an atom - that is, the ionization of the atom - means a fundamental structural change in its surface layer.

Physicist

Used in scientific fields to describe electron transfer, implies complex processes.

Scientific Context

Ionization refers to creating charged particles, important in electricity.

Charge Creation

Ionization is often an invisible process, not directly observed.

Not Always Visible

Ionization is a result of specific actions like heat or nuclear reactions.

Cause and Effect

Refers to situations where ions are produced and exist, affecting the environment.

Presence of Ions

Ionization is key to forming plasma, a state of matter in stars and neon lights.

 that trapped bad tasting sediments from water. Today, point-of-use processes usually involve ionization to lower mineral content. They also use adsorption filtration, where a porous material called activated carbon
