This award would allow Drs. R. Jeffrey Wilkes, Thompson H. Burnett, and Jere J. Lord, University of Washington, Seattle, to collaborate with Dr. K.N. Ingvar Otterlund and his research group at the University of Lund, Sweden. They will study high energy heavy ion interactions. The purpose will be to search for the new state of nuclear matter, the quark-gluon plasma, which is predicted to be created in heavy ion collisions. Their research will be done at the heavy ion facility at the European Organization for Nuclear Research (CERN) in Geneva, Switzerland and at the Brookhaven National Laboratory in the United States. The heavy ions 16O and 32S will be accelerated to energies of 13-200 GEV/nucleon and then directed into emulsion chamber detectors, which are arrays of nuclear emulsion plates. The procedure will permit precise observations of the produced particle tracks. This experiment is possible because the new CERN heavy ion beam became available in late 1986. The research is strengthened because the U.S. group is expert in the design and construction of emulsion chambers, and their Swedish counterparts are strong in exposure arrangements and analysis of data, and they are well-known for their theoretical interpretation of multiparticle production. The proposed cooperation presents the U.S. investigators with an opportunity to work with one of the world's leading research groups and to use highly specialized facilities abroad that are not easily available to them in the U.S.

这一奖项将使R博士。作者：Jeffrey Wilkes，Thompson H.伯内特，以及 西雅图华盛顿大学的Jere J. Lord与 K.N.博士Ingvar Otterlund和他在牛津大学的研究小组 瑞典，隆德。 他们将研究高能重离子相互作用。 的 目的是寻找核物质的新状态， 夸克-胶子等离子体，预计将在重离子中产生 碰撞 他们的研究将在重离子设施进行， 位于日内瓦的欧洲核研究组织， 瑞士和美国布鲁克海文国家实验室 States. 重离子16 O和32 S将被加速到 13-200 GEV/核子，然后导入乳胶室检测器， 它们是核乳胶板的阵列。 程序将允许 对产生的粒子轨迹的精确观测。 本实验 是可能的，因为新的欧洲核子研究中心重离子束成为可用， 1986年末 研究得到加强，因为美国集团是 专业设计和建造乳胶室， 瑞典同行在曝光安排和分析方面很强 数据的丰富性，它们以其理论解释而闻名 多粒子生产。 拟议的合作提出了 美国调查人员有机会与世界上最大的 领导研究小组，并使用国外高度专业化的设施 在美国是不容易得到的。
