    摘要: A vacuum plasma system has a table with a table power connector, and a fixture spaced apart from the table for defining a chamber between the table and the fixture. An electrostatic chuck (ESC) is mounted to the table in the chamber. The ESC has a side for supporting a workpiece, and an ESC power connector that electrically couples with the table power connector. A coupling extends between the table and ESC power connectors to provide electrical connection therebetween. A shield surrounds the coupling and portions of the table and ESC power connectors to reduce external fields applied to the coupling.

    摘要: A marine seismic survey is performed in icy waters by initially planning a survey track traversing a survey area. The initial track is planned based on initial ice conditions in the survey area having the icy waters. After preparing the system, a seismic system is deployed into the water from a survey vessel at the survey area. This is typically done in an area relatively free of ice. At least one escort vessel escorts the survey vessel as it traverses the survey track and obtains seismic data. The survey vessel tows the seismic system under the surface of the icy water to avoid the ice. All the while, systems and operators monitor the survey area along the survey track for actual ice conditions. In this way, the escort vessel can handling the actual ice conditions along the survey track so the survey vessel does not need to halt.
