ABSTRACT:
The anodes in a ring laser gyroscope are appropriately positioned for the easy starting of a gas discharge and maintaining the discharge at a lower electrical potential. Two operating anodes are placed symmetrical with and in close proximity to a cathode while a third trigger anode is placed in direct line of sight with the cathode. This configuration allows ease in starting without using a very large starting voltage.
