Production of slow antihydrogen from cold antimatter plasmas. - 179 p.

Thesis (Ph.D.)--Harvard University, 2004.

Several major achievements are detailed in this thesis. Large numbers of antiprotons are captured and cooled to 4 Kelvin in a Penning trap. Antiprotons are provided by the Antiproton Decellerator at CERN, and the accumulation of cold, trapped antiprotons is found to increase in proportion to the number delivered by CERN. As many antiprotons as possible are required to achieve the goal of antihydrogen production.

520 $a Several major achievements are detailed in this thesis. Large numbers of antiprotons are captured and cooled to 4 Kelvin in a Penning trap. Antiprotons are provided by the Antiproton Decellerator at CERN, and the accumulation of cold, trapped antiprotons is found to increase in proportion to the number delivered by CERN. As many antiprotons as possible are required to achieve the goal of antihydrogen production.
520 $a The physical properties of positron and antiproton plasmas are measured for the first time in the ATRAP apparatus. These findings are essential for interpreting the results of antihydrogen experiments, for accurate calculations of recombination rates, and for the design of future experiments.
520 $a The interaction of antiprotons and positrons is induced by the application of radio-frequency drives. During the interaction large numbers of antihydrogen atoms are created and detected with a newly-devised background-free detection technique. A total of 718 atoms are directly detected in a 1 hour trial.
520 $a A series of experiments are performed to measure how tightly bound the atoms are, and a theoretical investigation is made of the dynamics of an atom under the experimental conditions. This infers a positron-antiproton separation of &sim;0.2 mum, which indicates that the atoms are formed in a three body recombination process, and then collisionally de-excited while inside the positron plasma.
