        Injection protection

        • checklist here
        • 1 yellow : BLM thresholds OK up to presently highest intensity injected. Continuous update of the test during ramp-up
        • 2 grey items: Blindable BLMs commissioning. Scheduled sometime after the scrubbing

         

        Extraction protection

        • checklist here
        • Beam commissioning completes
        • (11) Yellow
          • (1) Aperture in P6
            • for B1 using direct extraction with bump showed losses at a simulated 14.5MKDs.
            • However, comparison with previous years show similar behaviour at higher amplitudes.
            • Therefore the test this year may have seen higher tails from the pilot used.
            • No issues indicated by other measurement, hence recommending start of operation
          • (10) Intensity ramp-up items
        • (6) grey/TODO
          • (6) bort gap cleaning is not commissioined
