Application 07/801,248
DECISION ON APPEAL
This is a decision on appeal under 35 U.S.C. § 134 from
the final rejection of claims 1-10.
We reverse.
BACKGROUND
The disclosed invention is directed to a method and
apparatus for transporting an intense positive ion beam to a
distant target.
Claim 1 is reproduced below.
1. An apparatus for transporting an intense ion beam
comprising:
means for creating a plasma channel in a gas;
means for injecting a positive ion beam into said
channel at a mildly-relativistic mean velocity;
wherein the magnitude and direction of current
caused by propagation of said beam in said channel, the
magnitude of charge density in said beam, the magnitude
of charge density in said plasma channel, and said mean
velocity of ions in said ion beam are effective to
create net currents within said beam sufficient to
pinch said ion beam.
The examiner relies on the following prior art:
