        L-H transition

        TSVV3 private discussion following TSVV1-TSVV3 joint session

        Questions to address: do we believe we the phenomenology observed in GRILLIX and GBS is related to the L-H transition? Are they similar? Why is SOLEDGE3X behaving so differently? Can we sustain a pedestal?...
