“…Currently, internationally established detector systems for intermediate and low energy heavy ion collisions include the Large Area Silicon Strip Array (LASSA), the High Resolution Array detector arrays at Michigan State University in the United States [4], and the Charged Heavy Ion Mass and Energy Resolving Array (CHIMARA) detector array at the INFN National Laboratory in Italy [5]. To study the physical properties of secondary particles produced by the collision of intermediate and low energy heavy ions, we collaborated to construct the Compact Spectrometer for Heavy Ion Experiment (CSHINE) [6,7]. This was established on the Radioactive Ion Beam Line 1 in Lanzhou (RIBLL1) at the Heavy Ion Research Facility in Lanzhou (HIRFL).…”

In order to improve the counting rate and position resolution of the Parallel Plate Avalanche Counter (PPAC) within the Compact Spectrometer for Heavy Ion Experiment, a new strip film-structured PPAC has been developed. The developped PPAC detector consists of three layers of film electrodes. The upper and lower layers which serve as the anodes are comprised of self-developed strip film electrodes, oriented perpendicularly to each other. The middle layer utilizes double-sided aluminized Mylar film as the cathode. There is a 3 mm gap between each layer, and the detector has an effective area of 76 mm× 76 mm. Operating in a low-pressure environment with isobutane gas as the working medium, the performance of the PPAC has been measured using a 5.486 MeV α radiation source. The measurement results indicate that the overall position resolution of the PPAC attains approximately 380 μm, and the position resolution improves to 300 μm when using slit width correction. Finally, the Monte Carlo simulation has been performed to simulate the distribution of electrons generated by the detector's ionization under the same conditions on the anode readout strip. The simulation results closely matches the observed multiplicity of hit anode readout strips in measurement.

“…On the other hand, HBT correlation can be used to measure the spatial and temporal information of particle emission source in heavy-ion collisions, which can be used to extract the dynamic information of emission sources. Its related experimental measurement and theoretical analysis have therefore aroused great interests [17][18][19][20][21][22][23][24][25][26][27][28].…”

We used an Isospin dependent Quantum Molecular Dynamics (IQMD) model to simulate Au + Au collisions at beam energy E beam = 1.23A GeV, which corresponds to center of mass energy √ sNN = 2.4 GeV. Firstly, we obtained reasonable rapidity and transverse mass spectra of π − and π + as well as "apparent" temperature parameters in comparison with the HADES data. Then by calculating three-dimensional Hanbury Brown and Twiss (HBT) radius of same charged pion-pairs, we obtained the square difference of outward radius and sideward radius, i.e. R 2 out − R 2 side , as well as the freeze-out volume (V f o ), which were basically consistent with the trend of HADES experimental results. The azimuthal dependence of the HBT radii was also calculated by a matrix method, and corrected by the rotation matrix. In addition, the eccentricities of the xy-and zy-planes of pion-pair emissions were also extracted for different pair transverse momentum and collision centrality, which show that the xy-eccentricity increases with pair transverse momentum as well as centrality but not for zy-eccentricity, indicating a more asymmetric transverse emission of particle-pairs with higher transverse momentum in off-central collisions.

“…Our aim is to investigate the dependence of fragmentation cross sections on the isospin of a projectile, which can improve our understanding of the mechanism behind the fragmentation process. Experiments were performed at the Heavy Ion Research Facility (HIRFL) [24][25][26][27] of the Institute of Modern Physics, Chinese Academy of Sciences. An primary beam with an intensity of 10 6 particles per second was accelerated to 280 MeV/nucleon by the main Cooler Storage Ring (CSRm) synchrotron and impinged on a 15-mm-thick 9 Be production target.…”

The elemental fragmentation cross sections of boron fragments produced by stable and neutron-rich 12-16C beams with a carbon target were systematically measured at an incident beam energy of approximately 240 MeV/nucleon. The measured cross sections were found to increase as the projectile mass number increases. The observed feature is explained qualitatively based on the abrasion-ablation two-stage reaction model and is compared quantitatively with predictions from various reaction models, including empirical and statistical models. All models agree with the measured cross sections within a factor of 2.
