The stellarator design as I have said is never going to provide electric power within orders of magnitude as cheap as fossil fuels assuming it even works. What the W7-X is likely to do is prove that a reactor grade plasma can be heated and held for thirty minutes. Relative to this goal, this propose...

Look's like a successful model used for Tokamak's has been extended to 3-D for stellarators. This model will be used with the Wendelstein 7-X stellarator to test an idea to reduce plasma turbulence by about half. The X-7 will be used to experimentally confirm (or prove otherwise) whether this model ...

Wow, looked up the transmission of silicon wafers and it is closer to one micron! While its just 60% over 1.4 microns (high index) it certainly would be a cheap protection plate.

Again, face masks are our best (and currently, only) defense against Covid even with active spreaders close up and in an enclosed environment; see - https://www.cdc.gov/media/releases/2020/p0714-americans-to-wear-masks.html Anecdotal and unsupported speculation is not worth the risk - masks are prov...

Don't know the wavelength your using but if it is above 4 microns, a silicon wafer could be used to protect the ZnS window. Three inch diameter silicon wafers are rather cheap - or use to be; don't know if still avialable but might be worth looking in to if that wavelength is usable.

Is your chamber only reaching 100 microns or is that the gauge giving an inaccurate reading? Try the gauge just on the pump head and that will tell you: first, if the gauge is likely accurate; second, whether your chamber is leaking or not.

Obivously good for the infrared - so I assume that is their purpose? And why so many?

One item (the He leak detector) includes a turbo and auto controller built in. Even if the electrontics don't work for the mass detector, the turbo and controller are worth bidding upon. The lot of stainless steel bellows pipes would be good and I bet are much easier to win in a bid. Do they ship or...

So Phosphine (20 ppb) was found in Venus' atmosphere; there are no known natural processes that create this except life. That does not mean there is life just that until a better process is proposed, or a probe goes there and doesn't find it, then that is the best idea. Of course, I bet NASA and oth...

The key to a useful foreline pipe is that it not collaspe; the vacuum level (as long as plasticizers aren't an issue) capablities are not terribly critical.
