Tail-Catcher/Muon Tracker Prototype Vishnu V. Zutshi for NIU/NICADD
Goals for the TC/Muon System Provide a reasonable snapshot of the tail-end of the shower for simulation validation Prototype detector with high-fidelity to what is imagined for a generic LCD correcting for leakage understanding the impact of coil muon reconstruction + eflow fake rate 9/17/2018 V.

Shower Depth Shower depth dependent sampling weights (least squares minimization) are calculated with and without tail-catcher energy. Weights for layers get progressively “frozen”. 9/17/2018 V. Zutshi, ECFA, Durham

Absorber and Cart Good quality steel plates from Fermi scrap available (0.75 and 4 inches thick). Maximum size for the thicker plates is 1.066m x 1.2m. Cart being designed with about 10 tonne load capacity. Will have the capability for forward-backward and left-right motion. 9/17/2018 V. Zutshi, ECFA, Durham

Summary Strip-fiber R&D essentially done, we are entering construction phase. All the scintillator required for the device has been produced. Mechanical prototype cassette assembled. Hope to have the first fully instrumented layer readout before year-end. 9/17/2018 V. Zutshi, ECFA, Durham
