  20. 4. Status of JT-60U Tentative JT-60U Operation plan in FY2004. • H-MG will not be used. • T-MG will be used for heating. • Only commercial electric power line will be used for Toroidal coil. • BT is limited to < 3.2 T • Discrete BT - 19 -

  21. 5. Remote participation Previous access method DB server for DLS * Data Linkage System DLS* server JT-60U experiment DB server Naka main computer Remote user New access method O. Naito Direct access to JT-60 DB server • Users at remote sites can now access directly to the main computer at JAERI Naka site for viewing and analyzing JT-60U experiment data. • Remote users (both domestic and international) can use the same analysis tools as in Naka site provided they have appropriate X-window environment. - 20 -

  22. 5. Remote participation O. Naito Format of PDS has been simplified - 21 -

  23. 5. Remote participation O. Naito Change in the Proposal Document Sheet format • Due to the change in the remote access method, the format of PDS has been modified and somewhat simplified: • “Registration Items for DLS” • This section is now replaced by “Remote Access to JT-60 Data and Computers”. • “Research Plan” • Specification of “Codes and Programs” and “Exchange Data” is no longer necessary. • But as described in “Policy Agreement on the Usage of JT-60U Data and JAERI Computers”, data, codes, and computers must be used only for the official purpose granted in PDS. • “Notices” • A remark on the one-time password authentication system has been added. - 22 -

  24. 5. Remote participation O. Naito Requirements for remote access to JT-60U data • To access to JT-60U data, a remote user needs: • One’s name listed on the “Proposal Document Sheet” as a remote user • At least one on-site participation to JT-60U project • Signed “Policy Agreement on the Usage of JT-60U Data and JAERI Computers” sent to JAERI • On completion of these requirements, JAERI will provide a remote access account for computers at Naka site, along with a SecurID token necessary for one-time password authentication system. RSA SecurID token - 23 -

  26. 7. Future plan National Centralized Tokamak Program • Objectives: to realize high-beta steady-state operation with the use of reduced radio-activation ferritic steel in a collision-less regime. • Planning : For further progress in the high beta steady state research, the modification of JT-60 is regarded as “National centralized tokamak facility program”. Detailed design work is ongoing in collaboration with universities, institutes and industries in Japan. - 25 -
