Will a corona discharge form around a charged glass insulator (without a conductor)?

  1. Dec 24, 2012 #1
    ...........Considering there is NO dielectric breakdown or breaking of glass/dielectric..............

    Can there be a corona discharge ever around a charged glass/dielectric without a conductor in the vicinity?
    For instance; take a single-electrode glass high-vacuum tube, charge it to high voltage like 4 millions. Electrons will be emitted from the electrode in the vacuum, but will there be a CORONA discharge in the free air outside and around the glass-tube?

    Regards
