J-port was slow in obtaining high power operation even when isolated. Antenna performance for all antennas is limited by coupled power that results in faulting. |

| Physop summary for 1020916 SL Wukitch PO Mossessian Plan - RF conditionning Summary: Very good run from PO point of view. Just one fizzle at the beginning (shot 6) caused by too high gas pressure at startup. Then all plasmas. The rate of current rise was changing from shot to shot, but we were able to control it by small changes in the pre-puff length. Fields are stable. The toroidal field was changed from 5.4 T to 4.6 on shot 3, and then to 4.5 T on shot 18. 23 shots 3 tests 1 Fizzle 19 plasmas _________________________________________________________ 1020916001 Test ---------------------------------------------------------------------------- 1020916002 The second shot will be another test. ---------------------------------------------------------------------------- 1020916003 . . . . . . . . . . . . . . . . . . . Plasma. Startup is good, although the current rise may be a little slow. The TF was programed to ramp down from 6 to 5.4 T, (PO fault)), which it did.
