欧洲核子研究中心的反氢引力行为实验(GBAR)需要由新的ELENA同步加速器环提供的100 keV反质子的有效减速来合成反氢。这是使用静电减速光学器件和漂移管来实现的,漂移管被设计成当反质子束在内部时从-99 kV切换到地-本质上是带电粒子“电梯”-产生1 keV脉冲。我们描述的模拟,设计,施工和成功的测试减速装置在-92千伏在线与反质子从ELENA。
The GBAR (Gravitational Behavior of Antihydrogen at Rest) experiment at CERN requires efficient deceleration of 100 keV antiprotons provided by the new ELENA synchrotron ring to synthesize antihydrogen. This is accomplished using electrostatic deceleration optics and a drift tube that is designed to switch from -99 kV to ground when the antiproton bunch is inside – essentially a charged particle “elevator” – producing a 1 keV pulse. We describe the simulation, design, construction and successful testing of the decelerator device at -92 kV on-line with antiprotons from ELENA.
