charged particle

Any ion or subatomic particle that carries an electrical charge, e.g., in medicine, a proton used in radiation therapy. By convention, protons are positively charged particles; electrons, negatively charged.

The charged particle moving with the velocity v induces magnetic field H wrapped around its path.
The charged particles tend to excite the gases in the atmosphere which results in a glow that resembles gas in a fluorescent tube.
This region allows charged particles to travel into and out of the heliosphere along a smooth magnetic field line, instead of bouncing round in all directions as if trapped on local roads.
Voyager data from two onboard instruments that measure charged particles showed the spacecraft first entered this magnetic highway region on July 28, 2012.
In a theoretical model proposed by Begelman and Boulder colleagues, the charged particles are accelerated near the nebula's center.
Other applications may be adversely affected by unwanted charged particle motion effects, for example, multipaction in high-power high-frequency applications, where the desired electrical power of a device leads to problems like sparking.
When the charged particles hit the Earth's air molecules their energy is emitted as light
Experience in charged particle irradiation of tumors of the skull base: 1977-1992.
These do not improve breathing conditions, as the charged particles are also more attracted to the walls of your respiratory tract.
The observations also suggest that Ganymede, like Earth and Jupiter itself, has polar aurorae -- light displays created when charged particles collide with atmospheric gases.
The book consists of two parts: Part I focuses on the motion of charged particles in static fields, the theory of electron lenses, and the problems of formation and transport of intense electron beams are considered; Part II covers the principles and theory of the interaction of electron beams with electromagnetic waves in quasi-stationary systems (diodes, klystrons), systems with continuous interactions (traveling wave tubes and backward wave oscillators), crossed-field systems (traveling wave and backward wave tubes of M-type, magnetrons, crossed-field amplifiers.
Charged particles are forced to travel along the magnetic field lines that snake throughout space.
