  • Design and installation of extra high voltage cryogenic

    Nov 01, 2011Highlights We installed high voltage cryogenic dielectric test facilities including big FRP cryostat. We designed 3 m long and 2 m wide cryostat system with busing. Low temperature and high voltage bushing were fabricated and tested. CF4 gas shows excellent characteristics in low temperature insulation. High voltage bushing could be modified for low temperature environment.Cited by: 2

    The formation rate of the etch by-product in O2/ CF4 plasma depends on the flux of oxygen radicals and ions arriving at the film surface. The oxygen radical concentration in O2/ CF4 plasma is sensitivity affected by the CF4 mixing ratio, and it shows maximum at CF4/(O2+CF4) ratio of 10% which in turn gives rise to the highest etch rate.
