Re: Z-Pinch Renaissance

I do not know where people are seeing 10 million Isp. I read an Isp of ~360,000 seconds and 330 kN of thrust for the D+He3 configuration. http://adsabs.harvard.edu/abs/2018APS..DPPC11163S Building on the ZaP, ZaP-HD, and FuZE projects, scaling studies will be presented of an SFS Z-pinch as a fusion...

Re: Z-Pinch Renaissance

From what I have seen, they are already at 300kA with the current setup, but they need to upgrade the power supply for 400 kA. I didn't notice that in the start..... its weird, because all the results they listed for this 300kA pinch (1-2 keV ion temperatures, 1-2x10^23 m-3 densities and neutron yi...

Re: Small Tri Alpha news blurp

So my take away is that C2-W is performing OK, but they want to upgrade it one more time before we can see the anticipated results for this machine. They are sure are not moving as quickly as they (and we) originally hoped they would.

Re: Z-Pinch Renaissance

This is just published and related to FuZe investigation and characterization of the produced neutron flux: From what I gather is just more confirmation of the neutron production in FuZe and that these neutrons are indeed thermonuclear in nature. I am excited to see them move on to higher currents ...

Re: Z-Pinch Renaissance

Uri and his team will present a lot of interesting new papers at the 61st Annual Meeting of the APS Division of Plasma Physics. This one is standing out to me: Zap Energy Inc. (ZEI) is scaling the sheared-flow stabilized (SFS) Z-pinch toward fusion reactor conditions. The UW and LLNL collaborated on...

Re: Tokamak Energy news

This is really good news! It will be interesting to learn how these new high performance HTS magnets behave after prolonged irradiation tests. It will also be interesting to learn at some point where CFS is in their magnet development. https://www.tokamakenergy.co.uk/tokamak-energy-exceeds-target-o...

Re: ARPA-E Fusion Workshop 2019 Enabling Timely and Commercially Viable Fusion Energy

Lots of cool presentations there!
Looks like ZAP is pushing their FuZE device to 400kA and 10^8 neutrons/pulse. Not bad!

Re: Z-Pinch Renaissance

I don't want to have this thread drift too much off topic. I just want to add that I love MSNW's Fusion Driven Rocket design. I think it is amazing, since it does get a lot of thrust and has none of the problems you mentioned. I am not sure about the temperature problems of the Z- Pinch design. As f...

Re: Z-Pinch Renaissance

Maybe they didn't fully disclose the abilities of FuZE or it was built in a way to be easily upgradeable. After al they are now a commercial company and if I was in their shoes I would also not fully disclose what I am able to do unless i discuss with a qualified investor. Well, it is what Uri told...

Re: Z-Pinch Renaissance

ZAP is generally cautious and tries to avoid over hyping things. So your point is valid (and their wording makes sense).
That said, they are already moving on to higher currents, it seems. I am a bit surprised by that. I was under the impression that FuZE can't handle currents over 300 kA.

Re: Z-Pinch Renaissance

That video above is from May. They have proven that the neutrons are from D2 fusion. I will need to check it back again, I seem to remember that also in the video they said (like in the 2018 paper) that the neutron flux was "coherent" with Deuterium fusion occurences, but there was no definitive pr...

Re: Z-Pinch Renaissance

Zap Energy got the grant in November 2018, so it should almost be time for an update. If they can prove that the nature of neutrons generated was indeed coming from Deuterium fusion and that the system can scale as expected while keeping stability, we might have indeed the technological base for a ...

Re: Z-Pinch Renaissance

I love the Fusion Driven Rocket. It is foil liner compressed FRCs. It has a lot of thrust compared to other fusion engine designs and a Isp of 5000 is still plenty good. That said, if the Sheared Flow Stabilized Z- Pinch works, it would have this design beat in terms of Isp and thrust, which is quit...
