Description

Low-Gain Avalanche Diode (LGAD) sensor is one of candidate sensors for tracker at future hadron collider. To use this sensor as tracking detector, AC-LGAD sensor was developed which has both timing and spatial resolution. In high luminosity environment, a 30ps of timing resolution and O(10um) spatial resolution helps to reduce pileup effect and reconstruct tracks precisely. By optimization fabrication parameters, 80um pitch strip and 100um pitch pixel sensors are successfully produced. In this talk, I will present the performance of fine electrode pitch sensors such as pulse height, crosstalk size, timing resolution, inter electrode capacitance and radiation hardness evaluated using a beta-ray source and in 800MeV electron testbeam.
