The goals of ATRAP are to produce cold antihydrogen, trap the cold antihydrogen and then compare its properties to that of hydrogen at a very high accuracy. These goals have been pursued since the earliest TRAP experiments.
``For me, the most attractive way ... would be to capture the antihydrogen in a neutral particle trap ... The objective would be to then study the properties of a small number of [antihydrogen] atoms confined in the neutral trap for a long time."
