Abstract
An apparatus and method of use for injection, confinement, neutralization, acceleration and compression of an ion field using a solenoid having an axis of symmetry and supported within a vacuum space. A pair of magnetizable elements are positioned initially in spaced apart positions within the solenoid and after the solenoid is filled with ions from an ion source, the magnetizable elements are brought into close proximity to compress the ion field and accelerate its ions.

An apparatus for confining, neutralizing, compressing and accelerating an ion field in a vacuum space, the apparatus comprising:
- a solenoid energized for producing a magnetic field therein, the solenoid and the magnetic field having a common axis of symmetry;
- a pair of magnetizable elements positioned initially in distal opposition on the axis of symmetry;
- at least one ion source enabled and positioned to project a stream of ions into the solenoid, thereby establishing the ion field between the pair of magnetizable elements;
- a drive engaged with at least one of the magnetizable elements enabling the distance therebetween to be controlled;
- and a means for space charge neutralization, wherein the drive is energized to close the distance between the magnetizable elements thereby accelerating and compressing the ion field.
A method for confining, neutralizing, compressing and accelerating an ion field in a vacuum space, the method comprising the steps of:
- a) providing a solenoid having an axis of symmetry;
- a pair of magnetizable elements positioned initially at a fixed distance therebetween on the axis of symmetry;
- an ion source;
- a drive engaged with at least one of the magnetizable elements;
- and a means for space charge neutralization;
- b) energizing the solenoid to create an axial magnetic field therewithin for receiving ions emitted by the ion source;
- c) axially magnetizing a first one of the pair of magnetizable elements thereby forming a first magnetic mirror at a distal end of the solenoid;
- d) energizing the space charge neutralization means;
- e) injecting the ions into the solenoid axially toward the first magnetic mirror until a selected ion density is reached within the solenoid;
- f) axially magnetizing a second one of the pair of magnetizable elements thereby forming a second magnetic mirror at a second end of the solenoid;
- and
- g) energizing the drive to close the distance between the magnetic mirrors thereby accelerating and compressing the ion field;
- h) energizing the drive to open the distance between the magnetic mirrors, and demagnetizing the second one of the pair of magnetizable elements, thereby resetting initial conditions.
