Description

This contribution describes the first measurements of a resistive AC-coupled Low Gain Avalanche Diode (AC-LGAD) strip detector using $120$ GeV protons. AC-LGADs combine the precise time resolution of standard LGAD silicon sensors with precise spatial resolution, and make excellent candidates for future 4-dimensional tracking detectors. The sensor studied in this result has a strip pitch of $100~\rm{\mu m}$, and was produced at Brookhaven National Laboratory. Measurements were performed at the Fermilab Test Beam facility. In this result, we characterize the sensor signal properties, compare the experimental results with TCAD simulations, and demonstrate sensor efficiency $>99\%$.
