U.S.-Sweden Cooperative Research: High Energy Heavy Ion Interactions

该奖项将允许西雅图华盛顿大学的R.Jeffrey Wilkes博士、Thompson H.Burnett博士和Jere J.Lord博士与瑞典隆德大学的K.N.Ingvar Otterlund博士及其研究小组合作。他们将研究高能重离子相互作用。目的将是寻找核物质的新状态，夸克-胶子等离子体，预计将在重离子碰撞中产生。他们的研究将在瑞士日内瓦的欧洲核研究组织(CERN)的重离子设施和美国布鲁克海文国家实验室进行。重离子16O和32S将被加速到13-200GeV/核子的能量，然后被引导到乳胶室探测器，这是核乳胶板阵列。该程序将允许对产生的粒子轨迹进行精确观察。这项实验之所以可能，是因为新的欧洲核子研究中心重离子束于1986年底投入使用。这项研究之所以得到加强，是因为美国小组在乳胶室的设计和建造方面是专家，而他们的瑞典同行在曝光安排和数据分析方面很强，他们以对多粒子生产的理论解释而闻名。拟议中的合作为美国调查人员提供了与世界领先的研究小组之一合作的机会，并使用他们在美国不易获得的高度专业化的海外设施。

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.
