Papers on polywell research

Post by crowberry »

I could not search for older threads with the subject "papers" because it is an too common term according to the forum search function, so I created a new thread. Maybe one could collect in this thread new polywell papers?

There is a new published paper from the Sydney group:

Scaling law of electron confinement in a zero beta polywell device
David V. Gummersall, Matthew Carr, Scott Cornish, and Joe Kachan
Department of Plasma Physics, School of Physics A28, University of
Sydney, NSW 2006, Australia

Orbital theory simulation was applied to an electron trap that uses a
cube shaped magnetic cusp known as a Polywell device. The purpose of
this device is to create a virtual cathode in order to achieve nuclear
fusion using inertial electrostatic confinement. Analytical expressions
of the electron confinement time and average position within the device
were obtained in terms of the current in the field coils, the dimensions
of the device, and the kinetic energy of the electrons. Comparisons with
numerical simulations showed good agreement over a parameter range that
spanned several orders of magnitude for the current. In addition, power
loss from electrons exiting the trap was estimated in order to obtain
minimum power requirement to maintain a virtual cathode within the
device.

There are a whole bunch of papers/reports hosted on Askmar. Includes many from Bussard and EMC2 as well as other sources on topics either directly related to IEC/polywell or associated support technologies.
