Continuous electrode inertial electrostatic confinement fusion

Continuous electrode inertial electrostatic confinement fusion

Motivation:
Power availability as limiter to space exploration

No pressure vessel. Fusion not fission
Aneutronic shielding: no shielding
DEC direct energy conversion

Reduce mass by 4x
Fusers of the 60s
Radian acceeration of furl lions. T center, most unfortunately lost to cathode good.

The idea is to use a multi grid device, greater survivability of ions

Continuous electrode IEC
Simultaneous impact to the cathode, sloth thermalization process and this is important for aneutronic fuel.
System is highly transparent to the fusion products
Waste heat generated as a result of impact of ions and no additional radiators are necessitated forthesystem(radiators make a substantial mass of projected finished product)

C60 buckyball, each of the vertices from icosahedral, yield irregular hexagons and regular pentagons with roughly the same area
The center is where the fusion occurs… 32 channels, 16 beam lines

Aneutronic fuel
D-T lowest hanging fruit in terms of fuel
17..6 MeV >> 14.1 MeV neurtrons (low efficiency of the heat source)

So we focus on  p11 B 
Still poor thermal plasma performance, 175% bremsstrahlung losses
Possible to produce more fusion power, and is produced as alpha particles, @4MeV apiece and one around 1 MeV
Standing Wave Direct energy Converter:
Up to 90% energy extracted. Spread of energy loses more in alphas we will see.
QA
It has become clear that within the next 5-10 years something big will happen in fusion.
When will this move to phase 2?
Experimental confinement fusion elsewhere?
No.
Ions are primarily radially, hence the icasehedral design of the cofinemnet, it is a sort of geometry game to avoid some issues
A little curious if the 80% conversion efficiency is not that good? Also what about the 20% of alphas that can be very damaging floating around to existing structures?

We are perhaps naively hopeful that all alphas will leave the system, there is no entrapment in the system.
