A type of vacuum pump in which ionized gas molecules are attracted to a cathode by a high voltage where they remain trapped. Ionization Ionization is the process of removing electrons from neutral atoms and thereby producing ions. Because radiation causes ionization, this effect is often used to detect stray beams in particle accelerators and particle detectors. A high-accuracy vacuum gauge consisting of a vacuum tube whose emission current is proportional to the density of residual ions in the volume in which the tube is immersed. Ionizing Radiation Radiation of sufficiently high energy to cause ionization of the medium through which it passes.
Ionizing radiation can cause extensive damage to biological tissues.
IP Interaction Point. The point where two beams collide. IP Internet Protocol. The network layer protocol for the Internet protocol suite. The basic unit of information passed across the Internet.
