The overall goal of this research program is to use precise laser spectroscopy on the 1s-2s transition to probe for any tiny difference between antihydrogen atoms and hydrogen atoms, thereby providing the most sensitive tests of CPT (Charge conjugation, Parity, and Time reversal) invariance with baryons and leptons. The antihydrogen is formed in a nested Penning trap called ATRAP (Antihydrogen TRAP). ATRAP uses antiprotons from CERN's Antiproton Decelerator, and positrons from a radioactive source, to produce the cold antihydrogen. With the successful demonstration in 2002 of the formation of antihydrogen, the focus now turns to optimizing the production of antihydrogen and obtaining the first antihydrogen spectroscopy. The broad impacts of the program spans from the training of students to the impact of solenoid design on medical imaging to the education of the public on antimatter physics.

该研究计划的总体目的是在1S-2S过渡上使用精确的激光光谱法来探测抗氢原子和氢原子之间的任何微小差异，从而提供CPT的最敏感测试（电荷共轭​​，平等性，平等性和时间逆转）与Baryons和Lyptons的不变性。抗氢化是在称为Attrap（抗氢气陷阱）的嵌套笔陷阱中形成的。 ATRAP使用CERN抗蛋白质减速器中的抗蛋白酶，以及放射性源的正电子，以产生冷抗溶性。随着2002年成功的抗血解基因的成功示范，该重点现在转向优化抗溶质的产生，并获得了第一个抗溶质光谱。该计划的广泛影响涵盖了从培训学生到螺线管设计对医学成像的影响到公众对反物质物理学的教育。
