Positron plasma diagnostics and temperature control for antihydrogen production.

چکیده
Production of antihydrogen atoms by mixing antiprotons with a cold, confined, positron plasma depends critically on parameters such as the plasma density and temperature. We discuss nondestructive measurements, based on a novel, real-time analysis of excited, low-order plasma modes, that provide comprehensive characterization of the positron plasma in the ATHENA antihydrogen apparatus. The plasma length, radius, density, and total particle number are obtained. Measurement and control of plasma temperature variations, and the application to antihydrogen production experiments are discussed.

Temporally controlled modulation of antihydrogen production and the temperature scaling of antiproton-positron recombination.
We demonstrate temporally controlled modulation of cold antihydrogen production by periodic RF heating of a positron plasma during antiproton-positron mixing in a Penning trap. Our observations have established a pulsed source of atomic antimatter, with a rise time of about 1 s, and a pulse length ranging from 3 to 100 s. Time-sensitive antihydrogen detection and positron plasma diagnostics, bo...
متن کاملScaling behavior of the ground-state antihydrogen yield as a function of positron density and temperature from classical-trajectory Monte Carlo simulations
Antihydrogen production has reached such a level that precision spectroscopic measurements of its properties are within reach. In particular, the ground-state level population is of central interest for experiments aiming at antihydrogen spectroscopy. The positron density and temperature dependence of the ground-state yield is a result of the interplay between recombination, collisional, and ra...
متن کاملAntihydrogen trapping assisted by sympathetically cooled positrons
Antihydrogen, the bound state of an antiproton and a positron, is of interest for use in precision tests of natureʼs fundamental symmetries. Antihydrogen formed by carefully merging cold plasmas of positrons and antiprotons has recently been trapped in magnetic traps. The efficiency of trapping is strongly dependent on the temperature of the nascent antihydrogen, which, to be trapped, must have...
متن کاملInward transport and compression of a positron plasma by a rotating electric field
Inward transport of a magnetized pure positron plasma confined in a Penning-Malmberg trap is produced by applying a rotating electric field to the plasma. Compression is observed over a broad range of frequencies. Compression factors up to 20 in central density were obtained. Positron collisions with a neutral buffer gas are used to counteract the heating due to the rotating electric field. The...
متن کاملTransient Antihydrogen Production in a Paul Trap
Although positrons and antiprotons have vastly different masses, we show that it is possible to store both particle species simultaneously in a Paul trap, using the space charge of the positron cloud as a trap for the antiprotons. Computer simulations confirm the validity of this new trapping mechanism. In addition, the simulations show transient antihydrogen production that manifests itself in...
