STAR focus: Measurements of charged-particle multiplicity dependence of higher-order net-proton cumulants in p + p collisions at $\sqrt{s} = 200$ GeV from STAR at RHIC One of the ultimate goals of heavy-ion collision experiments is to map the phase diagram of nuclear matter, the so-called QCD phase diagram, with respect to temperature (T) and ...

2025年1月30日 · RHIC is a discovery machine in which STAR continues to play a central role with more than twenty-two RHIC runs of data collected and still more to come. The scientists in our collaboration come from 74 institutions across 14 countries, with more institutes joining us each year. The STAR Council is the governing board with representatives from ...

2024年5月24日 · The STAR detector specializes in tracking the thousands of particles produced by each ion collision at RHIC. Weighing 1,200 tons and as large as a house, STAR is a massive detector. It is used to search for signatures of the form of matter that RHIC was designed to create: the quark-gluon plasma (QGP).

2012年4月24日 · RHIC is the world's only machine capable of colliding beams of polarized protons to investigate the 'missing' spin of the proton. Accelerator Science Before high-speed packets of heavy ions can be brought into collisions with one another, they first travel through a chain of smaller particle accelerators.

工程物理系是rhic 上的螺旋形径迹探测器（star）国际合作组成员，自2001 年始，我们采用多气隙阻性板室（mrpc）技术为star 先后建造了大型飞行时间探测器（tof）和新型缪子探测器（mtd）。 整个tof 的时间分辨达到80ps，性能优良，运行稳定，大大提高了高动量区 ...

RHIC还可以进行偏振质子的对撞实验。偏振质子在 线性加速器 （ 英语 ： Linear particle accelerator ） 中产生，然后在辅助加速器、AGS和RHIC中进一步加速后对撞。 STAR （ 英语 ： STAR detector ） 和 PHENIX （ 英语 ： PHENIX detector ） 两个大型实验分别位于RHIC储存环 …

The Solenoidal Tracker at RHIC (STAR) is designed to detect charged and neutral particles produced in relativistic heavy ion collisions. The majority of the STAR data is provided by relatively slow detectors: TPC, SVT, FTPC, EMC. The trigger system must look at every RHIC crossing and decide whether or not to accept that event and initiate ...

2018年9月11日 · The STAR experiment at RHIC has been taking data since 2000. During that time, new detectors have been added, RHIC luminosity has increased, and STAR’s physics goals have become more focused. The Trigger System has evolved in parallel to be able to provide more precise triggering capabilities at higher rates. In this article the major ...

RHIC-STAR实验由来自13个国家67个单位的700多位科研人员组成。STAR中国组主导完成的飞行时间探测器在电子鉴别中发挥了关键作用。本研究数据分析部分主要由山东大学STAR组完成，并由J.D. Brandenburg代表STAR合作组在Quark Matter 2019国际会议上首次公开汇报。

2020年12月7日 · 近日，中科院近代物理研究所的科研人员参与rhic-star实验研究，利用star实验在每核子对质心能量7.7-39 gev范围内收集的金-金碰撞数据，测量了氘核的一种集体运动——直接流（v 1 ）随对撞能量、粒子快度以及横动量的变化过程。
