The Tuda programme

TUDA是TRIUMF/ISAC的一个设施，用于探测放射性束与稳定同位素靶反应产生的带电粒子，重点是核天体物理学。最初的设施是与爱丁堡大学的一个小组（后来约克大学加入）和TRIUMF的一个小组合作建立的。现有或拟议中的这些实验的探测器主要由英国合作部分提供，而TRIUMF和NSERC则为基础设施提供人员帮助。除了核天体物理计划外，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提供。2008年5月/6月，TUDA合作组成功地完成了一项核天体物理学实验，测量了^18F（p，alpha）^15O反应，因为^18F束已经在TRIUMF获得。由于放射性束的发展缓慢，这项合作提出的许多实验，特别是在核天体物理学方面的实验，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，这些实验涉及^8Li、^9Li、^9C和^11Li的散射，而不涉及来自英国的合作伙伴。另一个被提议的实验是测量^14 C（α，γ）^18 O（S1152）反应。由于^14 C具有放射性，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（带有捕集器的特殊粗加工部分）。我们打算利用位于洛斯阿拉莫斯的DANSE装置和TRIUMF注入靶来进行^26 Al（n，p）（n，alpa）反应的测量。我们还参与了荷兰格罗宁根KVI的一项实验，涉及^12 C的α散射。在TUDA集团内，有一名博士后研究员（Goetz Ruprecht），我们希望保持这种状态。这个人还参与了TACTIC探测器的开发。这样一个人已经被证明是非常有价值的设置和计划的所有实验，我们做了到目前为止。我们还聘请了一名研究生与UBC（P. P. Kokiewich）。

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).
