Saved tunes: 100518_1113.snapiosfc6 (strict) & 100518_1128.snapiosfc6 (tweaked). Emittance scan attached.
At noon, beam handed over to Sophia. She has questions about the defeats associated with the Q3 failure last year. Checking... done.
Summary of Q1/2/3 wiring status right now:
- Defeat remains on Q1.
- Q1+/- cables swapped at power supplies.
- Q2 output is normal (+ drives L/R and - drives T/B) and is opposite to Q1 and Q3.
- Q3 output is normal (+ drives T/B and - drives L/R).
- All wiring at DBs is normal.
Sophia is continuing her tuning using IOS tune as provided.
Later... Sophia reports that this beam transports nicely. That said, the IOS tune is a little different now. Compare attached below. |
