Abstract：
The methods for calculating the electrical field strength in gas detectors have been introduced in this paper. The process to calculate the electrical field in gas detectors with complex electrode structure based on ANSYS has been presented and the electrical field calculation of MSGC detector has been given as an example. The effect of electrical field on the performance of gas detector has also been discussed.
