Exempel på antiproton

• Even with the improved antiproton production and storage capacities expected soon, this amount of antimatter is beyond our reach.

• Again assuming a three-order of magnitude improvement in antiproton production efficiency, these gains are near break even in terms of net energy flow.

• Antielectrons or positrons are difficult to store in this way, so antiprotons are stored instead.

• For a hypothetical plasma composed of antiprotons and positrons, a potential dip would occur.

• Currently, antiprotons can only be stored for a few weeks and production is very low, but the problems with the storage and production are engineering problems, not physical problems.

• Iridium is used in particle physics for the production of antiprotons, a form of antimatter.

• For example, an antiproton and a positron can form an antihydrogen atom, which has almost exactly the same properties as a hydrogen atom.

• Whereas the common hydrogen atom is composed of an electron and proton, the antihydrogen atom is made up of a positron and antiproton.

• Several methods for the liquid-propellant thermal antimatter engine using the gamma rays produced by antiproton or positron annihilation have been proposed.

• For example, the charges of the proton and antiproton must sum to exactly zero.

• The divergence indicates that at a low temperature hydrogen-antihydrogen will not be produced, rather proton/antiproton and electron/antielectron.

• Protons consist of two up quarks and one down quark, while antiprotons consist of two anti-ups and an anti-down.

• As a result, scientists had to develop a number of techniques for creating and handling intense beams of antiprotons.

• This is inconsistent with predictions from most models of dark matter sources, in which the positron and antiproton excesses are correlated.

• Since then, several groups have studied antimatter-catalyzed micro fission/fusion engines in the lab (sometimes "antiproton" as opposed to "antimatter" or "antihydrogen").
