- Abstract
A new advanced radiofrequency quadrupole (RFQ) ion cooler for accelerator mass spectrometry has been developed for the Anion Laser Isobar Separator (ALIS) at CologneAMS. Based on the Ion-Laser Interaction Mass Spectrometry (ILIAMS) setup at the Vienna Environmental Research Accelerator (VERA), it features new guiding electrodes and ion optics trying to solve challenges in decelerating and trapping intense heavy molecular ion beams, such as SrF3−. Initial tests with 27AlO− and 63Cu− show ∼ 30% transmission and millisecond ion residence times, demonstrating that the cooler is functioning properly. While promising, further optimizations are needed to fully achieve the desired efficiency and stability.
