Summary

Link to report from morning meeting

Monday 12^th Mar

• Access.

8:30 meeting

Sunday 11^th Mar

• Morning: access for ATLAS cooling until ~15:00.
• Afternoon and evening : TOTEM and ALFA interlock tests, including SMP parameters.
• Commissioning of RQT13.L8B1 to 440 A (was 400 A).
• Squeeze test to 0.6 m - OK !
• Squeeze attempt for high beta (90 m) failed due to current limit in RQF (6400 A, 6415 A required).

9:00 meeting

Saturday 10^th Mar

• LBDS tests.
• 10:30 Beam to TI8 downstream TED.
• Problem with injection timing tables - fixed by expert. Some duplicate hidden tables in the MTG HW.
• 14:00 LBDS TSU tests finished.
• 15:00 Beam down to TI2 TED.
• MKE4 waveform scan in TI8 with probe bunches.
• MKI8 pulsing and tested.
• 23:00: MKI and LBDS tests finished and almost completed. Delay of ~160 ns on the MKIs to to adjusted.
• Overnight - run again through nominal sequence. Issue with RQT13.L8B1 were the IPNO is set to 400 A while 405 A are required for the squeeze.

9:00 meeting

Friday 9^th Mar

• TOTEM interlock tests.
• 20:00 All valves open, LHC closed.
• 21:30 : beam dumped armed for the first time in 2012 !
• Ramp with LBDS armed.
• 22:00 Machine at 4 TeV with armed beam dump.
• BETS interlock tests at 4 TeV on RBs, Q4s, MSDs.
• Cycle tests - so issue with settings incorporation.

8:30 meeting

Thursday 8^th Mar

• LBDS BETS tests. Machine cycled with most PCs, including the squeeze.

8:30 meeting

Wednesday 7^th Mar

• LBDS BETS test on RBs, Q4s and MSD in 6. OK.
• Beta* reconstruction and distribution test (SIS+SMP+MTG). Ok from injection to end of squeeze (0.6/3/0.6/3m).
• S23 through ramp and squeeze (except QTD/F) OK.

8:30 meeting

Tuesday 6^th Mar

• LBDS BETS test on RBs, Q4s and MSD in 6. RB45 missing. Calibration curves for Q4 and MSD were found clamped.
