3. IA rise time and ringing with KD*P and new IA waveform measured
4. CST/GPT simulations of R30-6 high/low by 1mm indicate no issue
COMMENT ON 20 Amp Trim System Preventative Maintenance 2026
Tunnel magnet connection inspections completed for the North Access powered magnets. One loose connection found and corrected for MQK6R01. The loose connection was associated with the magnet thermal interlock wiring, not the DC power wiring.

COMMENT ON SAM 2026 Box Supply Work Preventative Maintenance/interlock checks
Working under PTW - 11789. BSY1C has been tested up to 500A on the high-power resistive load. Replacing the control power transformer confirmed that it was the issue, as the supply could not stay on previously. The supply has been locked back out, and all resistive load connections will be removed tomorrow.
