Description
A challenge in preparing radioactive samples is the dependence on beam time at radioactive isotope facilities. One can imagine implanting large amounts of long-lived isotopes into a target at an isotope facility. The target is then brought to an offline laboratory where specific quantifies of the isotope are extracted from the target via laser ablation. The ablated ions can then be mass-selected to suppress ions from the target material and loaded into sensors.
We developed a spatially-selective laser ablation ion source to calibrate our mass spectrometry setup. The laser beam spot is positioned via movable mirrors on a target's surface. This allows the ablation of material only in specific, selectable regions. We proposed to investigate how efficient our setup can be to ablated and extracted implanted ions from the ion source for subsequent use in sensors.
