    Low Gain Avalanche Diodes (LGADs) are silicon sensors employing charge multiplication to achieve a charge gain in the order of 10. The initial development of these sensors was spur by the High Luminosity upgrade of the Large Hadron Collider (HL-LHC), where these sensors will be used to measure the time of arrival of minimum ionizing particles with a precision of about 30 ps. To achieve this...

    Low Gain Avalanche Detectors (LGADs) are characterized by a fast rise time (~500ps) and extremely good time resolution (down to 17ps). For the application of this technology to near future experiments, the intrinsic low granularity of LGADs and the large power consumption of readout chips for precise timing is problematic. AC-coupled LGADs, where the readout metal is AC-coupled through an...

    In the past 10 years, two design innovations, the introduction of low-gain (LGAD) and of resistive read-out (RSD), have radically changed the performance of silicon detectors. The LGAD mechanism, increasing the signal-to-noise ratio by about a factor of 20, leads to improved time resolution (typically 30 ps for a 50-micron thick sensor), while resistive read-out, sharing the collected charge...

    4D tracking will be a crucial component of any future collider experiment, as it provides pile-up discrimination (for high luminosity experiments) and time of flight (for precision experiments) without loss of spatial resolution. 4D tracking devices must be able to withstand the high radiation environment of the future collider experiments without a significant loss of precision. One such...
