Description
The AC-LGAD, functioning as a 4D detector, is capable of simultaneously delivering both timing and spatial information. Additionally, the strip AC-LGAD offers the advantage of reducing the number of readout channels while maintaining position resolution along the bending direction. This makes it an excellent candidate for timing tracker detectors in future colliders. However, the length of the strips in AC-LGADs significantly impacts their performance, particularly in terms of sensor capacitance, timing resolution, and power consumption of readout ASIC.
To evaluate these effects, simulations of AC-LGADs with varying structural and process parameters are conducted. These simulations focus on analyzing three key capacitances: bulk capacitance, capacitance between strips, and coupling capacitance. These capacitances play a crucial role in determining the overall performance of the sensors. The study also explores methods to minimize bulk capacitance and inter-strip capacitance.
In the latest submission from IHEP, AC-LGAD designs featuring strip lengths of 1 cm, 2 cm, and 4 cm, along with DC-LGAD, will be presented. Furthermore, adjustments to process parameters will be implemented to achieve improved spatial resolution, ensuring the detectors meet the requirements of future collider experiments.
