Abstract
A dielectric high gradient insulator device comprises a stack of at least two dielectric layers which are in physical contact with each other and which have different dielectric constants. At least two dielectric layers are configured to form a shaped electric field, when the device is placed between electrodes having a voltage difference. The shaped electric field is in a region proximal to a surface of the at least two dielectric layers, and causes deflection of negatively charged particles away from the surface, thereby inhibiting voltage breakdown of the device. A method of manufacturing the device is also presented.
Claims7
A dielectric high gradient insulator device comprising
- a stack of more than two dielectric layers aligned along a longitudinal axis
- and having different values of dielectric constant which are arranged in an alternating structure;
- at least one of the dielectric layers having a stepwise variation in dielectric constant;
- the layers configured to form a shaped electric field, when the device is placed between electrodes having a voltage difference;
- the shaped electric field being in a region proximal to a surface of the at least two layers, and deflecting negatively charged particles away from said surface;
- thereby inhibiting voltage breakdown of the device.
