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).
