Abstract
A borehole logging tool includes a particle accelerator including a Cockcroft-Walton voltage multiplier that provides linear axial and radial fields. The Cockcroft-Walton voltage multiplier includes capacitors that are arranged radially relative to one another, such that a linear voltage increase occurs between the capacitors. The particle accelerator is made by placing conductive foils on an insulating sheet, connecting the foils as a Cockcroft-Walton voltage multiplier, and rolling the insulating sheet with the foils into a cylinder to form the radially arranged capacitors.
