A New Large-area Muon Telescope Detector at Mid-rapidity at RHIC

$\mu$ particle identification at middle and high $p_{T}$ range is crucial for many interesting physics in heavy ion collision experiment, like the dimuon continuum, the quarkonia production, and the Drell-Yan process. Due to the electromagnetic nature of interaction, $\mu$ carries information with direct sensitivity to the early stage of the high-energy nuclear collision before chemical freezeout. More importantly, $\mu$ is a background free probe compared to electron with no photon conversion background and much less Dalitz decay. A large-area Muon Telescope Detector (MTD) at mid-rapidity at RHIC is proposed and under investigation. In this talk the simulation of $\mu$ detection and hadron rejection will be shown. The preliminary result of the first test in run 6 p+p collisions will be discussed. A significant enhancement of high $p_{T}$ charged particles is achieved in this test run. Finally the plans for future upgrade will be presented.
