US 2013/0251933 A1 · Fabrication of High Gradient Insulators By Stack Compression

Abstract

Individual layers of a high gradient insulator (HGI) are first pre-cut to their final dimensions. The pre-cut layers are then stacked to form an assembly that is subsequently pressed into an HGI unit with the desired dimension. The individual layers are stacked, and alignment is maintained, using a sacrificial alignment tube that is removed after the stack is hot pressed. The HGI's are used as high voltage vacuum insulators in energy storage and transmission structures or devices, e.g. in particle accelerators and pulsed power systems.

Dependent claims

A method of making a high gradient insulator (HGI) having a desired cross-section and height, comprising:

providing a plurality of conductor layers and of dielectric layers, each layer having the desired cross-section of the HGI;
providing an alignment tube;
stacking alternating conductor layers and dielectric layers, each with the desired cross-section, in or around the alignment tube to form a stacked assembly of substantially the desired height;
bonding the stacked assembly of alternating conductor layers and dielectric layers together while stacked in or around the alignment tube;
removing the alignment tube from the bonded stacked assembly to form the HGI.
