Tuesday, Feb 1, SWING
* running on LAr until 8pm ** 6 GeV 25 nA on LAr 70.7M events, runs 15289 - 15802 * empty LAr target * 1 hour empty target run, 150nA, beam blocker IN * beam blocker calibration
* insert single foil Sn (200 mg/cm2) target * beam blocker calibration for 6 GeV on single foil Sn target ** noticed that target cannot be in beam * beam line expert (Eugene) to the rescue: positions target per expert mode * from Run #15805 on: beam blocker calibration from 4 GeV run on Sn(x4) target is uploaded <-- * start running on repositioned target Sn with 90 nA, beam blocker IN ** tdcpcal3 histograms empty goes unnoticed
Wednesday, Feb 2, OWL
* continue running on Sn target with 90 nA, beam blocker IN ** some detector/DAQ issues, some beam issues ** tdcpcal3 histograms empty goes unnoticed ** BST has noisy strips with SN target and in beam *** expert: most prominent with tin target and this might be due to electrical conductivity of the foil
Wednesday Feb 2, DAY
* warming up LAr target to room temp while running * continue running on Sn target with 90 nA, beam blocker IN ** tdcpcal3 issuefixed ** more issues: HV drop pcal and ftof in sector 3, ok after turning HVs back on
* BST noisy strips: access hall to make a test with target motor off, no change
* performed beam blocker calibration with Sn target * continue running on Sn target with 90 nA, beam blocker IN
Wednesday, Feb 2, SWING
* continue running on Sn target with 90 nA, beam blocker IN * from Run#15819 on, beam blocker calibration from 4 GeV run on Sn(x4) target is uploaded <--
