From their lab data, the plasma doesn't look stable: http://www.aa.washington.edu/research/ZaP/publications/ICENES11_shumlak_poster.pdf

For years we've been hearing that EUV will be ready for production use in "just a few more years" and now they're applying nuclear fusion technologies to create the light source? That's almost comical.

Thanks for clarifying, but in any case the plasma stable duration is independent of power.

You can't avoid neutrals going out radially and skipping out the light emitted and charges moving axially.

A few clarifications: * Zplasma's design goal is higher power, not higher energy. * Our core technology is a flow-stabilized Z-pinch. While developed as part of nuclear fusion research, it is not related to nuclear fusion itself. * Our DPP source does use a plasma Z-pinch, but a flow-stabilized pinch, not the unstable pinch used by others in the past. * Our source ends without the explosive instabilities of other DPP sources, so it does not produce high-energy debris. * Optical collection in our design is side-on, not downstream. Thanks, Henry Berg, CEO, Zplasma, Inc.

Another example of a misguided group/startup. They focus so much on solving a big issue, but neglect to follow up on downstream system consequences. A longer pulse per cycle obviously exposes the downstream mirrors to more ionic bombardment, despite best mitigation efforts. They need to make a positive announcement before actual integration with collection optics. Obviously, they won't get anywhere with it.

In fact, the group uses a Z-pinch plasma, same as Ushio's DPP. They have to use xenon or tin, not hydrogen (deuterium/tritium) as the plasma medium. http://www.aa.washington.edu/research/ZaP/index.html

Nuclear fusion plasmas are deuterium, which don't emit EUV.

It is very impressive these advancements that we are currently having in the area of nuclear fusion research, hopefully soon everything will become reality in order to make a better world. http://www.youtube.com/watch?v=ro5-QYqqxzM

There's also a coarseness problem, where now you're dealing with resist outgassing, crosslinking and even ablation at J/cm^2 instead of mJ/cm^2.

IoT Network Shoot Out
July 16, 1pm EDT Thursday

Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion. Join in and ask his guests questions.
