Ying: Overview of critical fusion technology R&D issues for the coming 10 years 3:45 pm Group discussion on how the various proposed facilities (irradiation and non-irradiation) can contribute to improving the fusion technology knowledge base (resolving the critical fusion technology R&D issues), and also pros and cons associated with the various facilities (cost, irradiation volume, synergistic test capability, etc.); "strawman" tables will be generated before July 1 and distributed via email in order to initiate this process Steven J.

Steve Zinkle Wed 30 June 1999 11:52 Subject: Announcement Dear colleagues, Alice Ying and I have been assigned the task of organizing a critical discussion (and associated written document) for the upcoming Snowmass, Colorado fusion summer study on "Neutron Sources and Large-Scale Technology Facilities" (Chamber Science & Technology Key Question #4). As you are aware, the intention of the Snowmass workshop is to have candid discussions on the opportunities and directions for fusion R&D for the coming 10 years. A brief 2-page prospectus on the "Neutron Sources and Large-Scale Technology Facilities" topic was prepared a couple of months ago by Alice and myself, and posted on the Snowmass web site (see http://www.fusion.ucla.edu/snowmass/questions/prospectusCQ4.html). Since the Snowmass meeting will begin only 16 days from now, we need to finalize the oral presentations and finalize a draft position paper which can be circulated for community comment. There are two Snowmass sessions scheduled for CS&T key question #4, on Wednesday pm (between lunch and coffee break) and on Thursday pm (between coffee break and the social hour). Both of the sessions are 1 h 45 minutes long and are tentatively scheduled to be held in the Top of Village Condo #1. As a draft presentation schedule, we envision that the various neutron source concepts could be presented in the Wednesday pm session (laser, d-Li/IFMIF, p-Li/LEDA, gas dynamic trap, VNS...), and the Thursday pm session could focus on a critique of the advantages/disadvantages of each facility vis-a-vis the critical R&D issues for fusion technology in the next ten years. Each of these sessions will also include some discussion on non-irradiation large-scale facilities that might be needed in the next ten years (e.g., some sort of thermohydraulic loop for studying corrosion, pumping power requirements with/without insulators, etc.?). We anticipate that each neutron source concept might have an ~10 minute presentation plus 5 minutes discussion during the Wednesday pm session (we want to allow sufficient time for discussion of the various facilities). A draft schedule is listed below for your comments. I would be grateful if the proposed presenters could let me know if they (or one of their colleagues) are willing and able to make a short presentation during this time. I am sorry that we haven't contacted you earlier about these proposed presentations. Early next week we will be distributing to you for comment a draft opinion paper on Neutron Sources and Large-Scale Technology Facilities. Sincerely, Steve Zinkle
