Upcoming Beam Batches and Conditioning Status for LHC - Action Required by Friday Morning

We are currently managing several beam batches with specific readiness and outgassing conditions. The .25nsec batch comprises 2 batches with intensity of 1 to 1.2e11 eH/V, ready since 11/3, although H2 remains unchecked, while MKE4 is still outgassing. The 50nsec single batch from PSB is ready with an intensity of 1.35 to 1.45e11 eH/V, having been prepared since 18/3, with MKE4 outgassing. A double batch from the booster is ready in PS. Prioritize conditioning of TIDV and MKDH so we can inform LHC by Friday morning about the weekend's expectations.
