Description
Among the Future Collider proposals the Muon Collider offers unique advantages for advancing energy frontier research. However, the Beam Induced Background (BIB), from muon decay along the beam pipe, poses a significant challenge for detector design and events reconstruction. Despite the use of Tungsten conical absorbers in the forward regions, an irreducible component of BIB enters the detector, characterized by low momentum and out-of-time arrival component respect the bunch crossing. The BIB flux on the barrel inner face of the electromagnetic calorimeter is about 300 particles per $cm^{2}$, with a total ionizing dose of $10^{-4}$ Grad/y and a neutron fluence of $10^{14} n_{1MeV}cm^{-2}y^{-1}$. To mitigate BIB effects, innovative solutions are needed. One promising development is CRILIN (CRystal calorImeter with Longitudinal INformation), a semi-homogeneous electromagnetic calorimeter based on Lead Fluoride crystals ($PbF_{2}$) read by UV-extended Silicon Photomultipliers. This novel calorimeter proposal, featuring high granularity, longitudinal segmentation and excellent expected timing, offers the potential to mitigate BIB effects and achieve a high energy resolution (less than $10\% \sqrt{E}$). This talk will present simulation results on the performance of CRILIN and recent experimental test results from CRILIN prototype, highlighting its potential in the challenging Muon Collider environment.
