A MuID and Hadronic Calorimeter for a Second Detector at the EIC

This contribution reports on ongoing R&D on an iron/scintillator sampling calorimeter. This device could be integrated into the magnetic flux return of a second detector at the Electron-Ion Collider and would enable excellent muon ID and detection of neutral particles, which at the EIC are mostly K_L and neutrons. The detector will be able to use longitudinal segmentation as well as excellent timing for energy reconstruction and particle ID via shower shape and time-of-flight.

We present our work to optimize these aspects of the detector. Photon timing resolution remains a focal point of our work, and we have implemented a fast timing parameterization that allows for simulating the physics of the detector without simulating individual optical photons. Additional efforts have been made to optimize the detector design using machine learning techniques to maximize the muon identification and energy reconstruction capabilities. The simulation software will be crucial to the ongoing detector development as well as for simulating EIC physics that will be needed once the collider begins data taking.
