论文摘要

放射性同位素的高精度质谱法的性能通常会受到大量污染（包括分子物种）的阻碍，这是由于放射性束的产生而产生的。在本文中，我们报告了碰撞诱导的解离（CID）的发展，这是在Triumf的离子陷阱中用于原子和核科学（Titan）的实验的背景手段。进行了这项研究是为了表征放射性离子束的质量和纯度和分子污染物的还原，以允许对放射性同位素进行质量测量，从核稳定性中进一步进行。这是CID在隔离型放射性离子束设备上的首次演示，并且表明可以将分子污染降低至数量级。

The performance of high-precision mass spectrometry of radioactive isotopes can often be hindered by large amounts of contamination, including molecular species, stemming from the production of the radioactive beam. In this paper, we report on the development of Collision-Induced Dissociation (CID) as a means of background reduction for experiments at TRIUMF's Ion Trap for Atomic and Nuclear science (TITAN). This study was conducted to characterize the quality and purity of radioactive ion beams and the reduction of molecular contaminants to allow for mass measurements of radioactive isotopes to be done further from nuclear stability. This is the first demonstration of CID at an ISOL-type radioactive ion beam facility, and it is shown that molecular contamination can be reduced up to an order of magnitude.
