Electrostatic wire for stabilizing a charged particle beam
First Claim
1. In a system including a charged particle beam generator, an accelerator, and a beam transport pipe, apparatus for stabilizing a beam of electrically charged particles which are propelled and guided to travel in a selected direction, said apparatus comprised of:
- guiding means, disposed within said beam transport pipe, comprised of a material upon which an electric charge is induced by said electrically charged particle beam, said induced electric charge having a sign which is opposite to the sign of the electric charge of said particle beam, said electrically charged guiding means causing said particles of said particle beam to be electrically attracted to said guiding means, thus causing said particles to move toward and cluster around said guiding means to stabilize said particle beam as it travels.

Abstract
In combination with a charged particle beam generator and accelerator, apparatus and method are provided for stabilizing a beam of electrically charged particles. A guiding means, disposed within the particle beam, has an electric charge induced upon it by the charged particle beam. Because the sign of the electric charge on the guiding means and the sign of the particle beam are opposite, the particles are attracted toward and cluster around the guiding means to thereby stabilize the particle beam as it travels.

12. For use with a charged particle beam generator and accelerator, a method for guiding, focusing and damping transverse oscillations of a moving charged particle beam, comprising the steps of:
-
(a) disposing at least one guiding means substantially on the longitudinal axis of at least a portion of the particle beam; and (b) inducing with the particle beam an electric charge on the guiding means, which electric charge is opposite in sign to that of said particle beam, said guiding means thus causing said particles to move toward and cluster around said guiding means as said particle beam moves along its direction of travel. - View Dependent Claims (13)
