Preparing an Isotopically Pure ²²⁹Th Ion Beam for Studies of ^229mTh

We present a protocol for the generation of an isotopically purified low-energy ²²⁹Th ion beam from a ²³³U source. This ion beam is used for the direct detection of the ^229mTh ground-state decay via the internal-conversion decay channel. We also measure the internal conversion lifetime of ^229mTh as well.
