The core hypothesis underlying the ARCO patents was to generate copious amounts of MEV electrons along
magnetic field lines above the earth's surface as shown above. Resonance energy can be applied many ways to
objects. Wind was the force that created a resonance effect and toppled the Tacoma narrows bridge in 1940.

A resonant heating method of creating MEV electrons using RF waves was developed and exploited by the
Oak Ridge National Laboratory (ORNL) Subsequent plasma devices have generated MEV electrons in the
laboratory with resonant heating. A figure from the "
Large Helical Device" project depicts such electrons
confined by a magnetic field.
The ARCO patents by Dr. Eastlund, hypothesized a large phased array antenna located in Alaska with its RF
energy focused at altitudes 100km or more above the earth. The system is illustrated at the top of the page.
The frequency was t chosen to be in the 1-3 MHz range to create an electron resonance heating that would
create MEV electrons along the magnetic field lines. The RF beam is shown in yellow in the figure. The heating
process is depicted as a helix along a magnetic field line. The electrons spiral along the field line with
increasingly large orbits as their energy increases. MEV electrons are formed and a magnetic mirror force
pushes the electrons away from the earth along the magnetic field lines. When such electrons impinge on a
missile warhead or a satellite, they are buried in the material and heat components. In the case of a missile
warhead, this can lead to destruction, in the case of a satellite, it can make the satellite inoperative.

The first DOD contract regarding the ARCO patents by Eastlund was from DARPA and was entitled "The
Alaska North Slope Electric Missile Shield", contract No. DAAHD1-86-C-0420. The objective was to determine
the feasibility of generating the MEV electrons and determining the feasibility of the applications. A summary of
the work performed is available as a paper entitled "Applications of In Situ Generated Relativistic Electrons in
the Ionosphere", by Dr. Bernard J. Eastlund, December 13, 1990. ESEC Technical Report 136. Distribution of
this paper was authorized by DARPA in 1990. See letter below.
Eastlund's Patent 5,038,664 estimated
electron acceleration power requirement of
0.1 to 1 watt/cm2 at 250 KM.

This hypothesis was verified theoretically by
Menyuk et al, Phys. Rev. Letters, Vol. 58,
Number 20, May 18, 1987  who were
supported by the “Alaskan North Slope
Electric Missile Shield” contract. The paper
concludes that 0.5 watt/cm2 at 130 KM
could accelerate ambient electrons to 5
Dr. Eastlund was the principal investigator
on the contract.
The request for proposal by the Joint Services was issued in
February, 1990.
The bidders conference had only 13 attendees, reflecting the
closeness with which the project was held by APTI. Eastlund
was represented by 1 of the 13 attendees. On page 5 of that
document, In a section entitled, "Potential Applications" it is
stated that:

" Finally, the use of an HF heater to accelerate electrons to
Kev or MEV energy levels could be used, in conjunction with
satellite sensor measurements for controlled investigation of
the effects of high energy electrons on space platforms. There
already is indication that high power transmitters on
space-craft accelerate electrons in space to such high energy
levels, and that those charged particles can impact on the
space-craft with harmful effects. The processes which trigger
such phenomena and the development of techniques to avoid
or mitigate them could be investigated as part of the DOD
