Electrostatic field in the spark counter with a localized discharge

摘要

This paper describes the results of detailed field calculations for a parallel-plate spark counter. The computer code SAM for two-dimensional geometries based on a solution of Bound Integral Equations by a collocation method was used. An accuracy of electric field calculations is 10(sup -3). Typical execution time for one electrode geometry is less than 60 s on a PC-486. This allowed us to optimize an electrode shape and estimate influence of defects at an electrode surface on electric field. The results of the calculations are important for a choice of a spark counter design and technology for spark counter mass production. 10 refs., 15 figs. (Atomindex citation 27:011369)
