Scope of the Workshop The Workshop focused on the instrumentation for the major research areas that can be studied with radioactive ion beams at RIA. The program of the workshop consisted of overview talks, short presentations on specific experimental techniques and detectors, and parallel sessions of Working Groups. The overview talks served as the general introduction for the subsequent discussions of the detector systems by the Working Groups. Nearly half of the available time at the meeting was devoted to the technical discussions and evaluations of the proposed detectors by the Working Groups. Working Groups were formed to realize the following objectives for each of the six major equipment categories: i) Discuss and formulate the specifications and design criteria for detector systems at RIA, based on the experimental requirements, ii) Provide actual or preliminary conceptual designs for detectors that would meet the above specifications, iii) Offer cost-benefit analysis for competing design options, iv) Identify R&D requirements and road maps to accomplish them, v) Estimate the costs, manpower needs, and time schedules for completion of the major instruments, especially those with long R&D lead time. Summaries of the conclusions of the working groups were presented on March 22, and will become the basis of a report. The Working Groups and their conveners were: 1. Advanced concepts in gamma ray detection; 2. Neutron and charged-particle detectors; 3. Magnetic devices and separators; 4. Experiments with non-accelerated beams (detectors for decay spectroscopy, atom
and ion traps, lasers, etc.); 5. Advanced electronics & data acquisition; 6. Advanced targets (radioactive, gas, polarized, cryogenic) The conveners were assisted in their work by the interested researchers in each field who made poster or short oral contributions to the group. These contributions addressed a variety of technical details related to each instrument, such as experimental techniques, performance goals and specifications, existing or preliminary conceptual designs, emerging technologies, etc. Special attention was given to the problems and challenges (e.g., background radiation, weak beam intensity, inverse kinematics) that may be posed by the use of radioactive ion beams in experiments. Participants were strongly encouraged to join and actively contribute to one or more of the above Working Groups. Input was requested regarding any other equipment at RIA that might not be adequately covered under the above six categories. We anticipate that the Working Groups will continue their effort after the meeting to provide a forum for the community to improve and refine the preliminary concepts and designs that will be developed during the Workshop. To facilitate this, we have provided an archived mail list for each Working Group so that group members can exchange comments and ideas. To subscribe to any of these collaborative forums, please visit http://www.phy.ornl.gov/workshops/riadetectors/mailinglist.shtml. You will be asked to provide your e-mail address and a password. You will also receive an e-mail to confirm your request. Messages sent to these Mail-Lists will be distributed to all subscribers, and archived. Archived messages may be viewed on the web. Subscribers will have the option of unsubscribing at a later date, or to choose how to receive their messages. Please note that you can subscribe to these forums and participate in the electronic discussions even if you are not planning to attend the Workshop. We also plan to establish a web site to serve as a central location to store or link to the relevant technical documents. For
