Description

We present measurements on AC-LGADs (also named Resistive Silicon Detectors RSD), a version of LGAD which has shown to provide spatial resolution on the few 10‘s of micrometer scale based on charge sharing among neighboring pads.
Using focused IR-Laser scans directed alternatively at the read-out side on the front and the bias side on the back of the AC-LGAD, RSD produced by FBK have been investigated to understand the charge sharing properties as a function of process parameters, and where available, compared with beam tests and detailed TCAD simulation of the charge collection process.
