Another hybrid design idea

It may be difficult to separate "theory" from "application," but let''s see if this helps facilitate the discussion.

Just a couple ideas to add. First, I would suggest a second set of rods staggered to the outside of the first set, so that any neutrons will always have to pass through a rod on it's way to the outer wall. The outer wall should be made of a neutron-reflective material of course, and the inner wall and fuel rods should be composed of a material that is relatively transparent to neutrons, such as a zirconium alloy like Zircalloy.

Just my loose change...

I am looking at a change in the basic architecture of the Fusor as the starting point for future development, possibly leading to a Fusion/Fission reactor. I have rearranged the Fusor in an attempt to make it more effective. I call this the Linear Focused Fusion Reactor.

The Linear Focused Fusion Reactor is a form of “Fusor” but with a substantially different architecture. The architecture is cylindrical rather than spherical (there are some cylindrical Fusors), linear and focused from just two directions (compared to 360 degrees). The goal of this effort is to build a Linear Focused Fusion Reactor that can generate high neutron levels for use in a Fusion/Fission Engine for space energy and propulsion. The device is relatively simple and inexpensive to construct and based on well understood physics.

Benefits of the new architecture:
Compact cylindrical shape.
The fuel is completely ionized before it enters the reactor from each end. Current designs most often ionize the fuel slowly after it enters the reactor resulting in a very low level of active ions (>1%).
The reactor has a mechanism for confinement of low energy ions, at each end, which keeps them from flooding the reactor thereby reducing low energy (unproductive) collisions.
The center cathode grid is two-dimensional (rather than spherical), there are only two ways to approach the grid and each way is 180 degrees opposite resulting in high speed ion collisions. This is a major change in architecture and a patentable design.
The reactor operates at the “sweet spot” of D-T fusion at 100,000 volts on the center grid. However, this is achieved with only 50,000 volts since the well is two sided. Ions approaching the grid from either side are capable of fusion at or near the grid.
Another unique feature is that the ions that don’t fuse are collected at the end grids until they have sufficient energy to escape toward the center grid for another attempt. This keeps ions from randomly flowing around the reactor causing low energy collisions.
Permanent magnets are used to help confine the ions into a narrow band toward the center of the well.

Why are you using a old post by someone else (and 2004 no less)? Shouldn't you start a new thread?

Perhaps, but since it was related to Fusion/Fission it I just jumped in here.

Just that your thread and their's will confuse search features. Best to define your own thread.

A new thread better allows searches and responses.
