Electrical FeedThru
The low voltage feedthru is on the left and in place. The HV feedthru will connect thru the center port.
Low Voltage FeedThru
The low voltage feedthru will be connected to the outer grid and operate at ground potential. A second feedthru is available for future use to power an ion generator.
High Voltage Feed Thru
The high voltage feedthru is connected to the center grid and will operate up to about -30 kVdc
Hemisphere with Feedthrus
Here we can see the two electric feedthrus installed as well as a viewport and the discharge valve.
Hemispheres with Grids
Picture shows both inner and outer grids installed. On the lower left the connectoion between the LV feedthru and outer grid can be seen.
QA Approval
The Supervisor was called in to approve the installation of the inner and outer grids prior to final assembly.
Grid Installation
Close up view of the Grid installation. On the lower left and right the ceramic standoffs that isolate the outer grid from the chamber are obseved. Four views of the final assembly follow.
