Description
The DC-RSD is a thin LGAD sensor with a resistive DC-coupled read-out, that uses internal gain and intrinsic charge sharing to achieve excellent 4D-tracking capability with low electrodes density.
The DC-RSD1 production comprises matrices with both small and large pixels, and strips, with technological variations of electrode layout and resistive layer levels to investigate charge sharing and effective gain.
This contribution presents a summary of results obtained with the FBK DC-RSD1 production, including space and time resolutions, uniformity of response and detection efficiency for different sensor designs.
The measurements were carried out in three DESY test beam campaigns and complemented by dedicated laboratory studies. Updates on reconstruction methods, optimal sensor design parameters, and sensor occupancy limitation will also be discussed.
