A cylindrical GEM detector with analog readout for the BESIII experiment

2016

Abstract A cylindrical GEM detector with analog readout is under development for the upgrade of the Inner Tracker of the BESIII experiment at IHEP (Beijing). The new detector will match the requirements for momentum resolution ( σ pt / p t ~ 0.5 % at 1 GeV) and radial resolution ( σ xy ~ 120 μ m ) of the existing drift chamber and will improve significantly the spatial resolution along the beam direction ( σ z ~ 150 μ m ) with very small material budget (less than 1.5% of X 0 ). With respect to the state of the art the following innovations will be deployed: a lighter mechanical structure based on Rohacell, a new XV anode readout plane with jagged strip layout to reduce the parasitic capaci…
