9971845CebraThe goal of this project is the study of collisions between relativistic nuclei and ultimately the determination of the properties of nuclear matter over a wide range of temperatures and densities. Without the possibility of direct studies of nuclear matter in bulk (as in neutron stars, supernovae, or the Big Bang), one resorts to the challenging studies of finite and transient systems as provided by nucleus-nucleus collisions. This effort will be focused on participation in the construction effort for the STAR (Solenoidal Tracker At RHIC) experiment at RHIC (Relativistic Heavy Ion Collider) and analysis of the data which it generates. The STAR Collaboration was formed to search for signatures of the Quark Gluon Plasma (QGP), a phase of matter which dominated the early stages of the Big Bang. UCD has proposed tracking chambers which extend STAR's coverage into the forward regions close to the beam axis (high $\eta$), with momentum resolution and charge determination. Construction of these two small Forward tracking chambers (FTPCs), which will fit inside the central tracking chamber (TPC), is now underway at MPI (Munich). The FTPCs for STAR will be installed for the second running period in year 2000. UCD will use the STAR central TPC and the FTPCs to continue their studies of transverse, elliptic, radial, and longitudinal flow. These studies of the hydrodynamical behavior of nuclear matter allow one to study its compressibility, and hence the nuclear equation of state.

该项目的9971845头脑的目标是研究相对论核之间的碰撞，并最终确定核物质在广泛的温度和密度范围内的性质。 如果没有可能直接研究批量研究的核物质（如中子恒星，超新星或大爆炸），人们可以诉诸于核核核酸核碰撞提供的有限和瞬态系统的挑战性研究。这项工作将集中在RHIC（相对论重离子对撞机）的Star（RHIC螺线管跟踪器）实验的施工工作以及对其生成的数据的分析。 形成了明星合作，以搜索Quark Gluon等离子体（QGP）的签名，这是一个阶段的阶段，在大爆炸的早期阶段占据了主导地位。 UCD提出了拟议的跟踪室，该室将恒星的覆盖范围扩展到靠近梁轴（高$ \ eta $）附近的向前区域，并具有动量分辨率和电荷确定。现在在MPI（慕尼黑）正在进行的两个适合中央跟踪室（TPC）内的小型前向跟踪室（FTPC）。 STAR的FTPC将在2000年的第二个运行期间安装。UCD将使用Star Central TPC和FTPC继续研究横向，椭圆，径向和纵向流量。这些关于核物质流体动力学行为的研究使人们可以研究其可压缩性，从而研究状态的核方程。
