Exotic radionuclides such as for instance 44Ti, 60Fe, 26Al, 10Be and many others are of great interest in several research domains like astrophysics, nuclear medicine, geophysics, fundamental nuclear physics or radioactive beam facilities. In the following, some examples are mentioned:
The Paul Scherrer Institue owns one of the most powerful accelerators in Europe, the ring-cyclotron with 590 MeV proton energy and 1.5 mA beam current. Several long-term-irradiated materials, stemming from beamdumps, targets and shielding equipment, are available at the moment for studies and first preparative work. PSI proposes a four-step-collaboration program:
The 1st ERAWAST workshop, hold from 15th till 17th November 2006 at PSI Villigen, was used to get in contact with interested partners, define the research activities and establish a working program for the next 5 years (e.g. topic 1 and probably 2). The working program consists of objectives realizable with relatively small amounts of material (laboratory scale), test runs, prototypes and development of principal technical solutions. Topics 3 and 4 can be realized only in a long-term frame of about 10 years or more and require the acquisition of financial support from several sources (local from host institutions, EU- and national supported actions, networks, integrated projects and so on) for the realization of large scale technical solutions. Depending on the progresses and demands from science and technology the chemical separation techniques have to be modified and automated, especially in the field of medical application, as well as new suitable equipment will have to be developed. Basic and applied research areas will have to be re-defined. For continuation the collaboration, we applied for a future ESF program called ERIMAST (Exotic Radionuclides from Irradiated Materials for Science and Technology) as a management tool to maintain the contacts, report on recent results, modify the working program and define new objectives.
