TUDA is a facility at TRIUMF/ISAC to detect charged particles emanating from reactions of radioactive beams with a stable isotopic target emphasizing nuclear astrophysics. The original facility was set up in collaboration with a group from the University of Edinburgh (the University of York joined later) and a group at TRIUMF. Detectors for these experiments, existing or proposed, have been largely provided by the British part of the collaboration, while TRIUMF and NSERC provided for the infrastructure an help with personnel. Besides the nuclear astrophysics program some nuclear structure experiments led by the Saint Mary's group are also performed at TUDA. The detectors for these experiments are provided by Saint Mary's. In May/June of 2008 the TUDA collaboration has successfully completed an experiment in nuclear astrophysics measuring the ^18F(p,alpha)^15O reaction as ^18F beams have become available at TRIUMF. Many experiments proposed by this collaboration particularly in nuclear astrophysics still need execution due to the slow development of radioactive beams. As for Nuclear Structure experiments Tuda has been and will be used for TRIUMF Experiments 1056, 1057, and 1147 involving scattering of ^8Li, ^9Li, ^9C, ^11Li not involving partners from the UK. Another experiment proposed is a measurement of the ^14C(alpha,gamma)^18O (S1152) reaction. As the ^14C is radioactive with a long half-life it is commercially available and we plan to run it from the OLIS off line ion source. This requires some dedicated equipment (a special roughing section with traps). We are about to propose an experiment to measure the ^26Al(n,p)(n,alpa) reactions using a TRIUMF implanted target and the DANSE facility at Los Alamos. We are also participating in an experiment at the KVI, Groningen, the Netherlands, involving alpha scattering on ^12C. Within the TUDA group a postdoctoral fellow (Goetz Ruprecht) is available and we wish to keep it so. This individual is also involved with the development of the TACTIC detector. Such a person has proven to be extremely valuable to set up and plan for all the experiments, we did so far. We also employ a graduate student in conjunction with UBC (P. Bruskiewich).

TUDA 是 TRIUMF/ISAC 的一个设施，用于检测放射性束与稳定同位素目标反应发出的带电粒子，强调核天体物理学。最初的设施是与爱丁堡大学的一个团队（后来约克大学加入）和 TRIUMF 的一个团队合作建立的。用于这些实验的探测器，无论是现有的还是拟议的，主要由英国部分的合作提供，而 TRIUMF 和 NSERC 则为基础设施提供了人员帮助。除了核天体物理项目外，圣玛丽小组领导的一些核结构实验也在 TUDA 进行。这些实验的探测器由圣玛丽医院提供。 2008 年 5 月/6 月，TUDA 合作成功完成了一项核天体物理学实验，测量 ^18F(p,alpha)^15O 反应，因为 TRIUMF 已提供 ^18F 光束。由于放射性束发展缓慢，此次合作提出的许多实验，特别是核天体物理学领域的实验仍然需要执行。至于核结构实验，Tuda 已经并将用于 TRIUMF 实验 1056、1057 和 1147，涉及 ^8Li、^9Li、^9C、^11Li 的散射，不涉及来自英国的合作伙伴。提出的另一个实验是测量 ^14C(alpha,gamma)^18O (S1152) 反应。由于 ^14C 具有放射性且半衰期长，因此可以在市场上买到，我们计划从 OLIS 离线离子源运行它。这需要一些专用设备（带有陷阱的特殊粗加工部分）。我们即将提出一项实验，使用 TRIUMF 植入靶和洛斯阿拉莫斯的 DANSE 设施来测量 ^26Al(n,p)(n,alpa) 反应。我们还参与了荷兰格罗宁根 KVI 的一项实验，涉及 ^12C 上的 alpha 散射。 TUDA 小组内有一名博士后研究员 (Goetz Ruprecht)，我们希望保持这种状态。此人还参与了 TACTIC 探测器的开发。事实证明，这样的人对于我们迄今为止所做的所有实验的设置和计划都非常有价值。我们还与 UBC 联合聘用了一名研究生 (P. Bruskiewich)。
