High Quality Actinide Targets

Abstract

We prepare high quality actinide targets for studies of neutron induced and charged particle induced fission. I report on our efforts to measure fragment energy loss in the target backings and to diagnose the crud problem frequently found in 248Cm and 252Cf sources and targets. I discuss the preparation of multi-isotopic targets for the Fission TPC and our efforts to measure the pointing resolution of this device. The issues of target uniformity, chemical composition and radiation stability of the targets are discussed along with problems of high/low specific activity regions in a single target.
