More quartz! Shown here is the beginning of a Polaris vacuum vessel being removed from its spinning mold; these large tubes are made with fused silica (quartz). Next up, this tube will be machined to create a final vacuum vessel. Each end of Polaris will have a large tube, and our team is making several tubes now to down-select for the highest performance. #quartz #hardtech
I am impressed!
Id like to see the machining of those little puppies
Bet those blocking paddles got hot.

1moIs quartz selected for its high heat tolerance and potentially greater resistance to wear from the formed plasma?
