flea jumping

Flea main project, the brain reader, implies a lot of rather special 
technologies, each is a gamble and some thinking must be invested in 
alternative solutions. The main challenge may be the nuclear pumping with 
entangled optical photons. Making the holographic mirrors for that task is a 
big project in itself. So, it may be useful to find an alternative. The only 
one is a fusion device. With He3 load and shapped charge, there may be a 
single domain of nuclear spin orientation when fusion starts. The down 
cascading of nuclei may then produce highly entangled X-rays in a laser 
process. Such radiation would be directly usable in the interferometer, 
without recourse to non-linear states of individual nuclei.

This process works only if nuclear spins are cooled at bulk scale. There is 
no way to get it outside fast compression out of thermodynamical equilibrium 
(The volume shrink faster than the temperature can scale up, so entropy must 
go down. Because this is contrary to the second thermodynamics principle, 
some disorder is pumped at another scale, namely the nuclear one. When all 
nuclei are cooled they fall in the same quantum state and fusion can start.

We know that in military devices, compression is produced by the rocket 
effect generated by x-ray evaporation of an outher capsule. The X-rays come 
from a fission trigger. Great efforts have been spent to duplicate that with 
laser or particle beams with no success up to now. Powerful electric 
discharges in a double crown of wires seem a better solution. That is all for 
official civilian researches.

Recently, a system dubbed lasertron has produced (on the paper!) another way 
to ignition: Very strong laser pulses along a rod would generate a strong 
electromagnetic field able to accelerate a plasma until fusion energy. This 
would work too with radio frequency waves sent along a "needle" with a 
reflector at end. That kind of fusion device would not produce a coherent 
high entanglement X-ray pulse, but its X-ray flash could be used in a staged 
device to compress a larger fusion load. 

A fast gun using solid rocket propellant load could launch a shell at 3000 
m/s. If stopped in a magnetic field in an Electro-Magnetic Pulse device, it 
could, after proper shapping of the pulse, produce the needle field of a 
lasertron.

Another gun solution, is to fire two hollow shapped shells one against the 
other and put at the contact point a frozen load made from deuterium-tritium 
mixed with xenon. With rocket propellant and litium hydride, the speed may be 
near 4000 m/s. Shock waves in a tungsten shapped charge my propel a dart at 
four time that value, so in head to head collision the relative speed would 
be 32 km/s. Compressing hydrogen-xenon, a product with low sound speed that 
way would pump entropy from the nuclear level. A trigger (classical) X-ray 
source would then start the fusion process.

The velocity in the above solution is at the limit to start fusion with one 
dimensional compression. It don't produce neither a single nuclear spin 
domain. The fusion pulse would then be used to compress a larger shapped 
charge. If the hydrogen-xenon charge was suppressed, an aluminium ball could 
convert the impact energy into X-rays, producing a 100 nano-second pulse. 
Specially studied optical fibers could compress in time that to 10 ns, giving 
a better rocket compression effect.

The canadian engeener John Bull seems to have studied a similar system: A big 
gun worked as the first stage of a two stages gun, the second using helium. A 
shapped hollow shell would have been launched at 9 Km/s, producing at impact 
a 36 Km/s dart. Two head to head such guns would have started without problem 
a fusion reaction in hydrogen-xenon. He was killed by Israeli secret service 
when he built one such gun in Irak. A rocket could not launch such a nuke, 
but it could have been put on an oil tanker. With staging, the explosion at 
sea of a 100 + Mt device would have drown Israel under a giant tsunami.

A powerfull, pulse mode MHD generator could produce a discharge in helium, 
able to launch a shapped charge at 10+ km/s, without supergun. This seems to 
be the best laboratory scale fusion device without fission trigger. Megaton 
yeld would be only two stages or so away.
