Description
The Future Circular electron-positron Collider (FCC-ee) will operate as a high-luminosity e⁺e⁻ collider for precision studies of the Z, W, Higgs bosons, and top quark. Its goals include electroweak and Higgs precision tests, searches for physics beyond the Standard Model, and providing inputs for future hadron collider programs.
A high-performance muon detector at the FCC-ee is crucial for accurately identifying and reconstructing muons produced in collisions, which are key signatures in many electroweak and Higgs studies. We propose to build a hybrid muon detector system that combines drift tubes with plastic scintillator strips. The design features one or more super-layers, each consisting of several layers of drift tubes for high-precision tracking in the bending plane (x, y). Nested above and below the tubes, orthogonally oriented layers of triangular scintillator strips provide precise z-coordinate information and fast timing signals. These strips are equipped with wavelength-shifting (WLS) fibers for efficient light collection and read out at both ends using SiPMs, enabling robust amplitude and timing measurements. The system targets a z-position resolution of 1 mm, using the strip cross-section size, the vernier effect between adjacent strips, or both. Simultaneously, the dual-end readout is designed to achieve a 200-ps resolution for time-of-flight measurements, and to determine the (x, y) position with a precision of O(1 cm) from the scintillator strips.
In this presentation, we will discuss the development of scintillator strip detectors for this application. We will present results from detailed simulations, along with experimental data obtained from recent test-beam campaigns with prototype detectors.
