论文摘要
自旋物理检测器是Jinr(DUBNA)正在建设的NICA对撞机的两个大型设置之一。 SPD研究的最终目标是测量极化的质子 - 蛋白质和deuteron-deuteron中不同自旋可观察物的碰撞,对核子的极化Gluon结构敏感,最高可达10 $^{32} $ cm^{ - $ cm^{-2} { - 2} \ cdot s^{ - cdot s^{-227 g} $ 1} SPD将包括超导磁系统,硅跟踪器,稻草迷你浇口跟踪器,飞行时间系统,电磁“ Shashlyk” - 类型的量热计,MUON(范围)和局部极光仪系统。高性能传播的DAQ系统将能够以高达4 MHz的碰撞速率运行。
The Spin Physics Detector is one of two large setups at the NICA collider under construction at JINR (Dubna). The ultimate goal of the studies at SPD is the measurement of different spin observables in polarized proton-proton and deuteron-deuteron collisions sensitive to the polarized gluon structure of the nucleon at the luminosity up to 10$^{32}$ $cm^{-2}\cdot s^{-1}$ and $\sqrt{s}$ up to 27 GeV. SPD will consist of the superconducting magnetic system, silicon tracker, straw mini-drift tubes tracker, time-of-flight system, electromagnetic "shashlyk"- type calorimeter, muon (range) and local-polarimetry systems. The high performance free-streaming DAQ system will be able to operate at the collision rate up to 4 MHz.
