ALPHA (Antihydrogen Laser Physics Apparatus) is an international project at CERN whose goal is to perform fundamental symmetry tests on trapped antihydrogen, the simplest atomic form of neutral antimatter. Since its approval by CERN in 2005, ALPHA has made significant progress. In November 2010, ALPHA announced the first stable trapping of antihydrogen atoms. Soon after, ALPHA reported the confinement of cold antihydrogen for as long as 1000 seconds, extending the initial trapping times by nearly 4 orders of magnitude.

阿尔法(反氢激光物理装置)是欧洲核子研究中心的一个国际项目，其目标是对捕获的反氢进行基本对称性测试，反氢是中性反物质最简单的原子形式。自2005年获得欧洲核子研究组织批准以来，Alpha已经取得了重大进展。2010年11月，阿尔法宣布首次稳定捕获反氢原子。不久之后，阿尔法报告了冷反氢的禁闭时间长达1000秒，将最初的捕获时间延长了近4个数量级。
