DEFINITION

Classification: 324/463

Using a magnetic field:

(under subclass 460) Subject matter wherein a magnetic field is used with an ionizing electron source to cause the electrons to flow in a longer path.

(1) Note. This longer path increases the probability of ionizing collisions.

(2) Note. The magnetic field here is not used to ionize the gas. The field can be alternating current or direct current and can originate from an electromagnet or permanent magnet.
