| Popis: | The wedge strip anode (WSA) detector has been widely used in particle detection. In this work, a novel model for calculating the inter-electrode capacitance of WSA was proposed on the basis of conformal transformations and the partial capacitance method. Based on the model, the inter-electrode capacitance within a period was calculated besides the total inter-electrode capacitance. As a result, the effects of the WSA design parameters on the inter-electrode capacitance are systematically analyzed. It is found that the inter-electrode capacitance monotonically increases with insulated gap and substrate permittivity but not with the period. In order to prove the validation of the model, two round WSAs were manufactured by employing the picosecond laser micro-machining technology. It is found that 9%–15% errors between the theoretical and experimental results can be obtained, which is better than that obtained by employing ANSYS software. |
