Triton

Triton

The nucleus of ²₁H (tritium); it is the only known radioactive nuclide belonging to hydrogen. The triton is produced in nuclear reactors by neutron absorption in deuterium (²₁H + ¹₀n → + + γ), and decays by β^- emission to ³₂H with a half-life of 12.4 years. Much of the interest in producing ³₁H arises from the fact that the fusion reaction ³₁H + ¹₁H → ⁴₂H releases about 20 MeV of energy. Tritons are also used as projectiles in nuclear bombardment experiments. See Nuclear reaction

Triton

(trÿ -ton) The largest satellite of Neptune, discovered in 1846 by William Lassell. It has a retrograde orbit and is gradually spiraling in toward Neptune. In about 100 million years it will be inside Neptune's Roche limit. Triton is very cold, with a surface temperature of only 37 K, and possesses a tenuous atmosphere mostly of nitrogen, but with some methane and traces of carbon monoxide. It has a pinkish south polar cap, probably a layer of nitrogen snow and ice. Extensively photographed in 1989 by Voyager 2, Triton shows an extremely complex surface. Its largest crater is 27 km in diameter, it has no mountains, but it has long cracks up to 80 km wide. It also has a ‘wrinkled’ terrain resembling the skin of a cantaloupe melon, and nitrogen geysers reaching 8 km high. See also Neptune's satellites; Table 2, backmatter.

Triton

(processor)

Intel's Pentium core logic chip set. In addition to the traditional features, this chip set supports: EDO DRAM to increase the bandwidth of the DRAM interface; "pipelined burst SRAM" for a cheaper, faster second level cache; "bus master IDE" control logic to reduce processor load; a plug and play port for easy implementation of functions such as audio.

The Triton I chipset (official name 82430FX) consists of 4 chips: one 82437FX TSC (Triton Sysetm Controller), two 82438FX TDP (Triton Data Path), and one 82371FB PIIX (PCI IDE Xcellerator). It supports PB Cache, EDO DRAM, and a maximum PCI and memory burst data transfer rate of 100 megabytes per second.

There are also Moble Triton (82430MX), Triton II (82430HX), and the Triton VX (82430VX) chip sets.

Triton

 

a satellite of the planet Neptune. Triton’s diameter is about 4,000 km, and its mean distance from the center of Neptune is 354,000 km. Triton was discovered in 1846 by the English astronomer W. Lassell. It revolves around Neptune in the retrograde direction, that is, in the direction opposite to that of the planet’s rotation.

Triton

 

the nucleus of an atom of tritium, a radioactive isotope of hydrogen. The symbol for a triton is t. A tritón consists of three nucleons, namely, one proton and two neutrons. It has a mass of 3.01646 atomic mass units, a spin of 1/2 (in units of h), and a magnetic moment of 2.979 nuclear magnetons. The mean binding energy of the nucleons is 2.78 million electron volts.
