Production of Antihydrogen
Results are presented for a measurement for the production of the anti-hydrogen atom H 0 pe + , the simplest atomic bound state of antimatter. A method has been used by the PS210 collaboration at LEAR which assumes that the production of H 0 is predominantly mediated by the e + e ? { pair creation via the two{photon mechanism in the antiproton{nucleus interaction. Neutral H 0 atoms are identiie...
متن کاملFirst laser-controlled antihydrogen production.
Lasers are used for the first time to control the production of antihydrogen (H ). Sequential, resonant charge exchange collisions are involved in a method that is very different than the only other method used so far-producing slow H during positron cooling of antiprotons in a nested Penning trap. Two attractive features are that the laser frequencies determine the H binding energy, and that t...
متن کاملAntimatter Gravity and Antihydrogen Production
Certain modern theories of gravity predict that antimatter will fall differently than matter in the Earth’s gravitational field. However, no experimental tests of gravity on antimatter exist and all conclusions drawn from experiments on matter depend, at some level, on a specific model. We have proposed a direct measurement that would compare the gravitational acceleration of antiprotons to tha...
متن کاملAntihydrogen production within a Penning-Ioffe trap.
Slow antihydrogen (H) is produced within a Penning trap that is located within a quadrupole Ioffe trap, the latter intended to ultimately confine extremely cold, ground-state H[over ] atoms. Observed H[over ] atoms in this configuration resolve a debate about whether positrons and antiprotons can be brought together to form atoms within the divergent magnetic fields of a quadrupole Ioffe trap. ...
متن کاملDriven production of cold antihydrogen and the first measured distribution of antihydrogen states.
Cold antihydrogen is produced when antiprotons are repeatedly driven into collisions with cold positrons within a nested Penning trap. Efficient antihydrogen production takes place during many cycles of positron cooling of antiprotons. A first measurement of a distribution of antihydrogen states is made using a preionizing electric field between separated production and detection regions. Survi...
