Abstract
A problem that occurs with MicroStrip Gas Chambers (MSGCs) is breakdow n between the electrodes. We have used two techniques to simulate and study this. The three dimensional electric field has been modelled by a computer simulation in which a finite number of point charges are mo ved to their equilibrium positions within the electrodes. Secondly, a real 40 x scale model of our MSGC was operated at 1/40th of normal pre ssure. Results from both techniques lead us to a new shape for the end s of the cathode strips.
