Abstract
An apparatus and method for prevention of migration of mobile ions in a gyroscope. A dielectric barrier material layer is placed between a gyroscope body and one or more gyroscope components. The dielectric barrier material layer reduces the electric field formed in the gyroscope block, and thus reduces ion migration therein. The material may prevent mobile ions from reaching the cathode seal.
