摘要
经比利时物理学会提名,欧洲物理学会(EPS)决定授予位于卢万-拉-纽夫(Louvain-la-Neuve)的回旋加速器大厅(Cyclotron Hall)历史遗址奖(图1)。1990年,这个地方举办了一项世界领先的核天体物理学实验,首次涉及短寿命放射性元素的后加速,并成功研究了恒星中的关键核反应。这次全球首演是来自比利时三所大学(ULB、KU Leuven和UCLouvain)的研究团队密切合作的结果。在比利时,只有另外两个EPS历史遗址(EPS历史遗址欧洲物理学会(EPS)):布鲁塞尔的大都会酒店(“1911年,该酒店是索尔维理事会的会场,致力于不久将被称为“辐射与量子理论”)和鲁汶的海利格-吉斯学院(“大爆炸理论的原始创始人Georges lematre,在这个学院发展了他关于宇宙膨胀与理论和观测相一致的想法”)。为了庆祝这一事件,纪念板于2021年10月12日星期二在UCLouvain的“de Hemptinne”大楼揭幕,该大楼设有回旋加速器大厅(图1)。纪念板上写着以下文字:这座建筑举办了一项世界领先的核物理实验,涉及短寿命放射性核素的后加速。1989年6月21日,通过将两个回旋加速器与联机离子源耦合,首次产生了半衰期为10分钟的氮的不稳定同位素N束。1990年12月,该光束的能量、强度和纯度使人们能够成功地研究热碳-氮-氧(CNO)循环中的关键恒星反应:N + H -> 14 O + γ。产生和使用高能放射性离子束的技术和仪器的发展,以及用短寿命放射性同位素进行详细核反应研究成为可能的证据,导致了核物理学和天体物理学中新的研究领域的诞生。这一加速器、核物理和核天体物理研究的突破是来自比利时鲁汶大学、鲁汶大学和鲁汶大学的团队密切合作的结果。它为涉及欧洲主要合作的放射性离子束的大量具有挑战性的实验铺平了道路,并导致世界上许多国家建造了生产放射性离子束的重要设施。此后,采用后加速同位素分离器在线技术或与之互补的飞行技术产生的放射性离子束领域在世界各地蓬勃发展,产生了新的放射性核束(RNB)系列会议,其中第二次会议于1991年在开创性实验后不久在卢万-拉-纽夫举行。“欧洲外来光束学院”致力于培养放射性光束科学的博士生和年轻研究人员,于1993年启动,直到2000年在鲁汶大学主持。从那时起,它走遍了欧洲,并于2017年回到鲁汶,庆祝第25所学校。2011年,第一届放射性同位素科学进展会议在鲁汶召开,是外来核与原子质量会议和RNB会议的合并,现在是该领域的旗舰会议。
The Cyclotron Hall of Louvain-la-Neuve, Birthplace of Postaccelerated Radioactive Ion Beams for Nuclear and Astrophysics Research
The European Physical Society (EPS), upon nomination by the Belgian Physical Society, has decided to confer a Historic Site Award to the Cyclotron Hall in Louvain-la-Neuve (Figure 1). This place hosted in 1990 a worldleading nuclear-astrophysics experiment involving for the first time the post-acceleration of a short-lived radioactive element and the successful study of a key nuclear reaction in the stars. This world premiere was the result of an intensive collaboration between research teams from three Belgian universities: ULB, KU Leuven and UCLouvain. There are only two other EPS historic sites in Belgium (EPS Historic Sites European Physical Society (EPS): the Hotel Metropole in Brussels (‘In 1911, the Hotel was the venue of the Solvay Council, dedicated to what soon would be called “The Theory of Radiation & Quanta”’) and the Heilige-Geest college in Leuven (“Georges Lemaître, original founder of the theory of the Big Bang, developed in this college his ideas about an expanding universe consistent with theory and observations”). To celebrate this event, a commemorative plate was unveiled on Tuesday, 12 October 2021, at the “de Hemptinne” building of UCLouvain, which hosts the Cyclotron Hall (Figure 1). The commemorative plate holds the following text: This building has hosted a worldleading nuclear-physics experiment involving the post-acceleration of shortlived radioactive nuclides.
