Off-line ion production
The MiniRFQ Laser Ablation Ion Source
Since the experiment is located within the controlled area of the TRIGA-Mainz research reactor, radioactive samples of sufficiently long-lived nuclides as well as of heavy elements above uranium can be measured off-line.
For off-line ion production we developed at TRIGA-Trap a novel laser ablation ion source, where the laser ablation target [1] sits in a gas-filled miniature radio-frequency quadrupole (MiniRFQ) [2].
The laser ablation process is driven by a pulsed, frequency-doubled Nd:YAG laser, which can deliver pulses with a length of 5 ns and energies of up to 12 mJ at a wavelength of 532 nm, at arepetion rate of 15 Hz.
