Patent ID: 8269510

Claim:
An apparatus, comprising: a chamber formed from an electrically conductive material, the chamber electrically connected to a ground potential; a hot electrode disposed in a substantially horizontal orientation within the chamber and physically separated from the chamber, the hot electrode formed from an electrically conductive material and including a top surface exposed to physically contact and support a part to be measured when placed upon the top surface, the hot electrode separable from the part to be measured such that the part to be measured can be placed on and removed from the hot electrode; a radiofrequency (RF) transmission rod connected to a bottom surface of the hot electrode, the RF transmission rod disposed to extend from the bottom surface of the hot electrode through an opening in a bottom of the chamber and be physically separated from the chamber, the RF transmission rod defined to transmit RF power to the hot electrode; and an upper electrode disposed in a substantially horizontal orientation within the chamber above the hot electrode, the upper electrode formed from an electrically conductive material and electrically connected to the chamber, the upper electrode defined to be movable in a vertical direction within the chamber.
