A penning ion trap for sympathetic cooling of highly charged ions with electrons and cold protons

用于原子和核科学的TRIUMF离子阱（TITAN）设施是一个多组分离子阱系统，在原子，核，中微子和粒子物理领域提供独特的研究可能性。该系统旨在实现短寿命放射性核的最大性能，因此为位于TRIUMF的世界级奇异光束设施ISAC的实验提供了理想的工具。计划用TITAN进行的实验包括用于测试粒子物理标准模型的高精度质量测定，远离稳定谷的原子核性质的研究，以及更好地理解晕核（具有非常大的“中子皮”的原子核）。TITAN的关键新功能之一将是能够在电子束离子阱（EBIT）中培育高电荷离子。为了降低高电荷离子离开息税前利润的动能，我们正在开发一种更冷的彭宁阱，在这种阱中，高电荷离子云与冷电子或质子等离子体同时被限制，从而导致高电荷离子的共感冷却。

The TRIUMF Ion Trap for Atomic and Nuclear science (TITAN) facility is a multi-component ion trap system that provides unique research possibilities in the fields of atomic, nuclear, neutrino and particle physics. The system is set up for maximum performance with short-lived radioactive nuclei, and hence provides an ideal tool for experiments at ISAC, a world-class exotic beam facility, located at TRIUMF. Proposed experiments to be carried out with TITAN include high precision mass determination for testing the Standard Model of Particle Physics, studies of the properties of nuclei far away from the valley of stability, and to gain better understanding of halo nuclei (atomic nuclei with a very large 'neutron skin'). One of the key new features of TITAN will be the capability to work with highly charged ions bred in an electron-beam ion trap (EBIT). To reduce the kinetic energy of the highly charged ions exiting the EBIT, we are developing a cooler Penning trap where clouds of highly charged ions are confined simultaneously with a cold electron or proton plasma, resulting in the sympathetic cooling of the highly charged ions.
