Efficiency optimization of the TRIGA-TRAP laser ablation ion source for transuranium elements
Mass measurements of longed-lived nuclides of transuranium elements are scheduled at TRIGA-TRAP in the near future. An important part of these experiments is the ionization of the elements of samples down to only a few nanogram. For this purpose, the existing laser ablation ion source, which was already used for mass measurements of stable nuclides, has been extended. A linear Paul trap has been added for ion acculmulation, cooling, and for mass selection.
The goal of a master thesis at TRIGA-TRAP is the optimization of the efficiency of the laser ablation ion source. Furthermore, the lower limit of the sample amount for a mass measurement with TRIGA-TRAP has to be determined.
The following techniques can be learned and improved:
- Production of ion beams
- Ion optics and beam transport
- Storing and cooling of charged particles
- High-precision mass spectrometry with Penning traps
