Baltensperger, R. Lorenzen COVER PHOTO: Accelerator SIMS allows very low level trace element detection in ultrapure materials. A view into the sputter- ing chamber through a vacuum window shows the target holder with a silicon sample and the cesium sputter gun. In order to avoid sample contamination all components are plated with pure gold.
