Abstract:Guiding of highly charged ions (HCI) through tilted capillaries promises to develop into a tool to efficiently collimate and focus low-energy ion beams to sub-micrometer size. One control parameter to optimize guiding is the residual electrical conductivity of the insulating material. Its strong (nearly exponential) temperature dependence is the key to transmission control and can be used to suppress transmission instabilities arising from large flux fluctuations of incident ions which otherwise would lead to … Show more
