1. Calculations of Beam Intensities Kick-off meeting, GSI, 17. 3. 2005 Task 11 : Calculations of Beam Intensities Kick-off meeting, GSI, 17. 3. 2005

2. Motivation for Task 11 The scope of the science addressed by EURISOL is strongly dependent on the beam intensities delivered. The major goal is establishing standard calculation procedures and codes, which are currently lacking, to facilitate comparison of various technical solutions for the facility. These codes will be based on existing experimental data, and, in a few specific cases, on new data acquired in the framework of the DS. In particular assessing the importance of having a driver with heavy-ion capability will be explored. The second important goal regards the investigation of novel ideas for secondary fragmentation and the assessment of the role of secondary reactions in single and two-stage targets, respectively.

14. Meetings, Feb. 05 - Jan. 06 It is planned to have a general meeting of all participants and contributors of Task 11 in February 2005 (the date is still not fixed). During this meeting, different working groups will be formed. Two other meetings of all participants and contributors are planned (after 6 months and after 12 months) where the results of the different working groups as well as deliverables and reports will be presented. Moreover, if necessary, the members of different working groups can meet more frequently.
