Properties of the QCD matter: review of selected results from the relativistic heavy ion collider beam energy scan (RHIC BES) program

In the paper, we discuss the development of the multigap resistive plate chamber time-of-flight (TOF) technology and the production of the solenoidal tracker at RHIC (STAR) TOF detector in China at the beginning of the twenty-first century. Subsequently, recent experimental results from the first beam energy scan program (BES-I) at the Relativistic Heavy Ion Collider (RHIC) pertaining to measurements of collectivity, chirality, criticality, global polarization, strangeness, heavy flavor, dilepton and light nuclei productions are reviewed.

X-Ray Generation for Diffraction Experiments on Z

Explanation of the concept and benefit of X-ray diffraction in the context of material sciences on Z. Explanation why we use ZBL and ZPW for these experiments and what the progress on X-ray generation for this purpose is.

X-ray Conversion Efficiencies for Diffraction Experiments on Z

We have used a deep-depletion CCD camera in single-hit mode to measure X-ray conversion efficiencies with Z-Beamlet and Z-Petawatt. Z-Petawatt is superior to Z-Beamlet for X-rays harder than 10 keV. For diffraction samples with Z > 42, we likely require X-rays with 15 keV or higher photon energy (Z-Petawatt). We are developing a robust, reproducible setup for X-ray polycapillaries as a part for X-ray diffraction experiments (XRD).
