-tron, -tronic, -tronics +
(Greek: a suffix referring to a device, tool, or instrument; more generally, used in the names of any kind of chamber or apparatus used in experiments)
A possible allusion to the Greek instrumental suffix, as in árotron, "plow" as spelled in the U.S. or "plough", as spelled by the British; from the Greek stem aroun, "to plow".
The suffix -tron is the result of the combining form extracted from electron, used with nouns or combining forms, principally in the names of electron tubes (ignitron; klystron; magnetron) and of devices for accelerating subatomic particles (cosmotron; cyclotron); also, more generally, in the names of any kind of chamber or apparatus used in experiments (biotron).
2. Velocity-modulated generator, such as a klystron tube (type of vacuum tube used as an amplifier), used to generate extremely high radio frequencies.
A klystron is an evacuated electron-beam tube in which an initial velocity modulation imparted to electrons in the beam results subsequently in density modulation of the beam. A klystron is used either as an amplifier in the microwave region or as an oscillator.
2. The energy required to release an electron from its atomic or molecular orbital.
2. A method of writing and storing large numbers of information elements electrostatically on the storage tape of a television information storage tube.
A dielectric-coated optical grating on the tape is bombarded with 10-keV electrons to induce momentary conductivity.
This causes electrons to flow fro the dielectric to the metal base of the tape.
Elemental areas on the surface of the tape lose charge in proportion to light from corresponding elemental areas of the image being stored.
Certain compounds entering the chamber have an affinity for these electrons, and this decrease in electrons is recorded for component identification.2. An extremely sensitive gas chromatography detector that is a modification of the argon ionization detector, with conditions adjusted to favor the formation of negative ions.
3. An item of laboratory equipment used coupled to a gas chromatograph for the detection and quantification of very minute amounts halogenated organic compounds.
The mass number is unchanged, but the atomic number is decreased by one and this process is accompanied by the emission of a neutrino.2. A radioactive decay process in which an atomic nucleus with an excess of protons draws an electron into itself, creating a neutron out of a proton and thus decreasing the atomic number by one.
Often the resulting nucleus is unstable and achieves stability by giving off a gamma ray.
2. A molecule that accepts electrons from electron donors and donates them to electron acceptors, creating an energy-producing electron transport chain; such as, that which occurs in respiration and photosynthesis.
3. A molecule associated with membrane-bound proteins that accepts and transfers electrons.
4. Any of various molecules that are capable of accepting one or two electrons from one molecule and donating them to another in the process of electron transport.
As the electrons are transferred from one electron carrier to another carrier, their energy level decreases, and energy is released.
2. The group or system of electrons revolving around the nucleus of an atom; a cloud-like group of electrons.
3. In a vacuum tube, the area between the electrodes that contains a great number of relatively stationary electrons.
2. An alloy of two metals in which a progressive change in composition is accompanied by a progression of phases, differing in crystal structure.
2. The orbital arrangement of an atom's electrons.
Negatively charged electrons are attracted to a positively charged nucleus to form an atom or an ion.3. The arrangement of electrons in an atom, molecule, or other physical structure; such as, a crystal.
4. The specific distribution of electrons in atomic orbitals of atoms or or ions.
2. A microwave amplifier tube where electron bunching is produced by an electron beam projected parallel to a magnetic field and is also influenced by a transverse electric field produced by a signal generator.
2. A method of coupling electrical energy from one circuit to another through the electron stream in a vacuum tube.
3. A process of coupling or linking two circuits inside an electron tube, used primarily with multigrid tubes.
The electron stream passing between electrodes in one circuit transfers energy to electrodes in the other circuit.
2. An electrode supplying current of charged heavy ions that uses microwave power to heat electrons to energies of tens of kilovolts in two magnetic mirror confinement chambers in a series.
Ions formed in the first chamber drift into the second chamber, where they become charged.
2. A wave in a plasma that moves parallel to the magnetic field produced by currents outside the plasma at frequencies less than that of the electron cyclotron resonance, and which is circularly polarized, rotating in the same sense as electrons in the plasma; responsible for whistlers.
A whistler is defined as an effect that occurs when a plasma disturbance, caused by a lightning discharge, travels out along lines of magnetic force of the earth's field and is reflected back to its origin from a magnetic point on the earth's surface.
2. The quantum mechanical probability density for an electron.
2. A device or tool in which conduction is principally by electrons moving through a vacuum, gas, or semiconductor; such as, in a crystal diode, electron tube, transistor, or selenium rectifier.
