(EDP Sciences)The CBM experiment, a fixed-target heavy-ion experiment at the upcoming GSI/FAIR SIS100 facility, aims to investigate QCD at high baryon densities. The CBM First-level Event Selector (FLES) serves as the central event selection system of the experiment. [...]

Low-metallicity stars are witnesses of the first stellar nucleosynthesis events in the Galaxy, as their surface abundances reflect the composition of the interstellar medium from which they were born. Aside from the primordial Big Bang nucleosynthesis, massive stars, due to their short lifetimes, dominate the wind and explosive ejecta into the interstellar medium of the early Galaxy [...]

The CBM First-level Event Selector (FLES) serves as the central data processing and event selection system for the upcoming CBM experiment at FAIR. Designed as a scalable high-performance computing cluster, it facilitates online analysis of unfiltered physics data at rates surpassing 1 TB/s.As the input to the FLES, the CBM detector subsystems deliver free-streaming, self-triggered data to the common readout interface (CRI), which is a custom FPGA PCIe board installed in the FLES entry nodes. [...]

Silicon strip sensors have long been a reliable technology for particle detection. Here, we push the limits of silicon tracking detectors by targeting an unprecedentedly low material budget of 2%–7% X0 in an 8-layer 4 m2 detector designed for high-occupancy environments (≤ 10 MHz/cm2). [...]

For the mitigation of the gas pollution effects in Multistrip Multigap Resistive Plate Chambers (MSMGRPCs) exposed to high irradiation doses, prototypes with a direct flow of the gas mixture through the gas gaps and discrete polyimide spacers were designed and assembled. The aging investigations of the chambers with the new design demonstrated negligible aging effects even for rather low gas flow rate. [...]

A free-streaming track reconstruction method has been developed for the CBM experiment at GSI. As a reconstruction core, it uses the existing singleevent tracking based on the Cellular Automaton, but the approach to the freestreaming tracking is generic and can be can be used with various core algorithms without modification.The method processes free-streaming data by manipulating the data at the input and output of the tracking core, leaving the reconstruction core unchanged. [...]

The Compressed Baryonic Matter (CBM) experiment is a next-generation heavy-ion experiment under development at the future FAIR facility in Darmstadt, Germany. It is designed to explore the QCD phase diagram at high net-baryon densities with unprecedented precision [...]
