在海德堡试验存储环上演示了快速存储离子束的三维激光冷却。在7.3 MeV{sup 3}Be{sup+}束上施加纯纵向冷却力，我们观察到了有效的横向冷却效应。我们将这一现象解释为由于库仑碰撞所产生的不同自由度之间的热束内弛豫所致。{版权所有}{1996年美国物理学会。}
Three-dimensional laser cooling of a fast stored ion beam has been demonstrated at the Heidelberg Test Storage Ring. With a purely longitudinal cooling force applied to a 7.3 MeV {sup 3}Be{sup +} beam, we have observed an efficient transverse cooling effect. We interpret this observation as being due to a thermal intrabeam relaxation between the different degrees of freedom that is caused by Coulomb collisions of the stored particles. {copyright} {ital 1996 The American Physical Society.}
