  1. LHC Status ThuMorning7-June Bernhard Holzer, JoergWenninger Status:

  2. WedMorning • 05:07h beam dump, water flow fault on converter RQ10.R1 • 09:18h start precycle (EDF during precycle ... once again) • 10:00h injection probe beam • 12:49h problem with cavity in PSB, beam quality not acceptable for injection • 16:29h injection probe beam • 16:56h injection physics beam • some optimisation done • 17:25h beam dump: power converter fault RBCV18.L4.B1 • de-activated (and masked) • ?? COD status in YASP ??

  3. WedLate 18:46h injection for physics not perfect but ok 20:04h stable beams for Mike ...

  4. Wed Late / Night • bunch losses during • squeeze / adjust / stable beams ... 8 % 10 % 03:31h Fast emittance scan after 7 hours of stable beams ... an easygoing luminosity fill

  5. Thu Morning • delivered luminosity in present fill:

  6. Thu Morning • Plan: • TCSG alignment verification in point 6 (B2) (1 hour) • Physics • Scan up to 3 sigma (CMS). Propose to do that with reduced damper gain at the end of the fill. ✔ ✔ ✔ ✔
