Field wire

What is Field wire?

Field wire meaning in Science terminology / glossary / dictionary is:
The thicker of the two types of wire in the central outer tracker (COT), their job is to create a difference in voltage that will send a floating electron toward the nearest sense wire. They also attract the positive ions whose electrons have been ripped away by a passing particle through the process of ionization. (See sense wires.) (Note: The positive ions do not actually move toward the field wires, but a positive ion will attract an electron from its neighbor, and so on down the line, effectively creating a wave of ion production.)
