Optimizing ion beam transport at the TITAN experiment using simulation, for the installation of a new linear Paul trap Javaji, Abhilash
Abstract
The TITAN experiment at TRIUMF performs experimental studies on stable and radioactive nuclei using ion traps as the main tools. While the primary scientific focus is high precision atomic mass spectrometry using a Penning trap, a future linear Paul trap (FLPT) is considered to enable a new class of decay spectroscopy studies. To aid the installation and integration of the FLPT into the TITAN beamline, studies were performed to optimize the transport of ions from the well established entry point within the experimental system to the location of the FLPT. These studies were performed by first understanding the basic beam dynamics principles dictating the transport of ions through electrostatic systems. Further, a simulation tool was set up using a commercial electromagnetic simulation software called SIMION to calculate the trajectories of ion beams in the beamline from the TITAN RFQ to the location of the FLPT. The tool was used to identify optimal settings for the ion optical elements for efficient ion beam transport. The simulation was employed to develop a tune with transmission efficiency of 100% and an output emittance at anticipated location of the FLPT that is acceptable for the device. The simulation tool allowed us to investigate issues with currently existing beamline ion optical elements that might require modifications. The tool was developed with modular features to allow for scaling to other components of the TITAN beamline. Recommendations are made for such improvements as well as for an optimized location for the FLPT decay spectroscopy system.
