Description
In this contribution, I will discuss two possible evolutions of the LGAD design.
-
DC-RSD: up to now, resistive read-out in silicon detectors has been used only in AC-coupled detectors, the so-called AC-RSD or AC-LGAD. I will present here the first attempt to apply resistive read-out to a DC-coupled sensor.
-
LGAD with bias ring: recent beam tests results showed that LGADs suffer destructive break-down if the field in the bulk is above 11V/um. SiPMs manage to survive similar conditions given the presence of quenching resistors. I will present a possible LGAD design that introduces AC-coupled read-out and quenching resistors in each pad. This design should also provide increased stability with respect to floating pads or pads with high currents.
