Performance of AC-LGAD strip sensors with laser and 120 GeV proton beam

AC-coupled Low Gain Avalanche Diode (AC-LGAD) sensors are a promising candidate as a 4D tracking system for future colliders like the Electron-Ion Collider (EIC). In order to meet EIC's detector requirements on performance metrics like position and timing resolution, efforts to understand and optimize AC-LGAD design parameters to achieve these targets are underway. In addition to test beam measurements, an in-house setup that can estimate AC-LGAD sensor performance and perform additional tests would be beneficial to speed up R&D efforts. This talk will describe the setup we constructed to study AC-LGAD sensors using an infrared laser source, and the methodology involved with measuring position resolution and the jitter contribution to timing resolution. Finally, we compare these results with those obtained using a 120 GeV proton beam.
