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.

原子和核科学（Titan）设施的Triumf离子陷阱是一种多组分的离子陷阱系统，可在原子，核，中微子和粒子物理学领域提供独特的研究可能性。该系统是通过短寿命的放射性核的最大性能设置的，因此为位于Triumf的世界一流的外来梁设施ISAC提供了理想的实验工具。建议使用泰坦进行的拟议实验包括高精度质量测定，以测试粒子物理学的标准模型，对远离稳定山谷的核的性质的研究，并更好地了解Halo nuclei（原子核具有非常大的“中子皮肤”）。泰坦的主要新功能之一将是与电子束离子陷阱（EBIT）中繁殖的高电荷离子一起工作的能力。为了降低出现EBIT的高电荷离子的动能，我们正在开发一个较冷的笔陷阱，在该陷阱中，高电荷离子的云与冷电子或质子血浆同时限制，从而导致高电荷离子的交感神经冷却。
