The ring beam acceptance is 800-pi mm-mr and the RTBT collimators have an acceptance of 400-pi. The acceptance of the final RTBT drift is only 220-pi mm-mr, and this needs to be increased. Studies of the effect of ring failure scenarios, such as painting failures, extraction failures, and magnet field loss and errors, will be conducted.
Shimming the high deviation ring dipole magnets to match the desired average integral field is working very well. The process shows no significant impact on higher multipole harmonics. Shimming a single magnet requires about one half day. So far, 16 magnets have been completed.
Global coordinates are being calculated using both Transport and MAD. Both IP and PI points will be generated.
The Koreans are designing a 100 MeV, 20 mA, CW linac over a 10 year, $100M project. They are developing ion sources and fabricating the LEBT and RFQ. Yoshii Yamazaki presented a JHF status report, describing a normal conducting 400 MeV linac with injection to an RCS. They are also looking at a 400-600 MeV SC linac for transmutation and developiong a 700 MHz klystron. For further details, contact Dong-o Jeon (7ax@ornl.gov) or Sang Ho Kim (6sk@ornl.gov).
