Mattman posted a link to the abstracts of the IEC 2015 conference in another thread. Here is the link to all the presentations of the conference: http://iec2015.es.titech.ac.jp/presentation/index.html. The talk by Joel Rogers is interesting Recent Polywell Patents, http://iec2015.es.titech.ac.jp/presentation/O-9.pdf.

From Joel's presentation:
A troubling problem has been discovered with conventional Polywell start-up.
● Negative space charge is trapped in the cusps. This shields out the potential well as density rises.

In other words, Joel's belief is that at beta = 1 the potential well is destroyed. Anyone given any thoughts to this claim? I know CSI has had trouble getting to beta = 1 condition and has had trouble with a deep potential well, but I blamed their trouble with the low potential well on leakage due to cusps not being closed off (EMC2 found that the start up requires jumping to beta = 1 to close off the cusps and required hefty electron guns to do that).

It is an important doubt because EMC2 has achieved beta = 1 and deep potential wells have been achieved, but not at the same time.
Near term, cheap, dark horse fusion hits the air waves, GF - TED, LM - Announcement. The race is on.

Joel has a ways to go from paper to action. EMC2's startup understanding is well beyond his.
