ATRAP Buffer-Gas Positron Accumulator
The ATRAP collaboration has been creating antihydrogen, the simplest antimatter atom, since 2002 and has a long-term goal of performing precision laser spectroscopy on these antihydrogen atoms. ATRAP has produced ...
Antihydrogen Via Two-Stage Charge Exchange
This thesis describes positron and antihydrogen research performed at CERN in the context of the ATRAP collaboration. Positrons emitted from a radioactive source are moderated in a layer of frozen neon. The rate at which ...
Testing CPT And Antigravity With Trapped Antihydrogen At ALPHA
High precision antihydrogen experiments allow tests of fundamental theoretical descriptions of nature. These experiments are performed with the ALPHA apparatus, where ultra-low energy antihydrogen is produced and confined ...
