b"Figure 4. A 3D printer laser ablation chamber fitted with a glass viewport for radioactive materials processing. Two holes on opposing sides were designed for Ar carrier gas flow to flow through the samber and carry ablation debris to the mass spec. This way, the cleanup process is simplified after laser processing, saving time and cost in performing the isotopic measurements on hot samples Accomplishments the various components we plan To develop a laser ablation Induc- on using inside of the containment tively Coupled Plasma - Mass Specchamber (e.g., micromanipulators, (ICP MS) system to process hotetc.).
