Description
AC-LGADs have been investigated widely due to their excellent time and spatial resolution, making them highly promising for future collider experiments. However, radiation exposure may damage the gain layer, thereby affecting the performance of AC-LGADs. We conducted a TID irradiation experiment on a 5.6 mm AC-LGAD strip designed by IHEP and fabricated by IME, and studied the electrical characteristics such as IV and CV under high-dose TID irradiation. Additionally, we investigated changes in spatial and time resolution using laser TCT and beta tests to evaluate the lifespan and expected operational performance of this type of detector.
