    NA61/SHINE results on multiplicity and net-charge fluctuations at CERN SPS energies

    Maćkowiak-Pawłowska🇵🇱

    This contribution presents final results on the energy dependence of multiplicity and net-electric charge fluctuations in Ar+Sc interactions collected by the NA61/SHINE experiment. Fluctuations were analyzed using higher-order cumulant ratios in Ar+Sc most central collisions and compared to p+p interactions. The results consider detector bias and centrality selection in the case of Ar+Sc. The results are compared across different energies and against model predictions.

    Physical Thickness Characterization of the FRIB Production Targets

    D. J. Lee🇩🇪 · M. Reaume🇩🇪 · W. Franklin🇩🇪 · J. Song🇩🇪

    The FRIB heavy-ion accelerator, commissioned in 2022, is a leading facility for producing rare isotope beams (RIBs) and exploring nuclei beyond the limits of stability. These RIBs are produced via reactions between stable primary beams and a graphite target. Approximately 20-40 \% of the primary beam power is deposited in the target, requiring efficient thermal dissipation. Currently, FRIB operates with a primary beam power of up to 20 kW. To enhance thermal dissipation efficiency, a single-slice rotating graphite target with a diameter of approximately 30 cm is employed. The effective target region is a 1 cm-wide outer rim of the graphite disc. To achieve high RIB production rates, the areal thickness variation must be constrained within 2 \%. This paper presents physical thickness characterizations of FRIB production targets with various nominal thicknesses, measured using a custom-built non-contact thickness measurement apparatus.
