An electron beam is generated in a packetized form defined by pulses having a duty cycle of less than 1:1000. Each pulse may have a width of approximately one microsecond (1. mu. sec. ) and may be separated by approximately one (1) second from the next pulse. The electrical beam may be accelerated, preferably linearly. The electrical beam may be modulated at a particular frequency (e. g. 3 gigahertz) by bunching the electrons during the beam acceleration. The electrons may be converted to photons (e. g. X-rays) by directing the electron beam to a target made from a suitable material (e. g. tungsten). The photons are then interacted with the electrical circuitry to produce photoelectrons. The photoelectrons impair the operation of the electronic circuitry by generating an electrical current in the electrical circuitry, generating capacitive charges in the circuitry and generating an electromagnetic field in the vicinity of the circuitry. The electrical circuitry may be disposed within an enclosure substantially impervious to the penetration of external electromagnetic fields, but passing energetic photons (x-rays).

The acceleration of large numbers of ions to high energies uses an intense relativistic electron beam produced by a vacuum diode. An electron beam radial profile is maintained by a strong longitudinal magnetic field. A virtual cathode, characterized by an electrostatic potential depression whose depth corresponds to the injected electron beam kinetic energy will form. The virtual cathode is caused to move backwards toward the vacuum diode by utilizing the time history of the injected electron beam voltage and current, and by appropriately flaring the drift tube. Ions trapped in the potential well associated with the virtual cathode move with the virtual cathode and are synchronously accelerated.

An accelerator directs an electron beam to a scanner which operates under microprocessor control to convert the beam into two (2) sets of spaced electron beamlets. A magnetic lens deflects the sets of beamlets to a spaced and substantially parallel relationship. A first dipole directs the first set of beamlets in a first direction to a first side of an article. A second dipole directs the second set of beamlets, in a second direction opposite to the first direction, to a second side of the article opposite to the first side of the article. In this way, a single accelerator irradiates two (2) opposite sides of the article with an enhanced precision, simplified controls, a significantly reduced number of components and reduced costs relative to the systems of the prior art. The electron beam may be converted to an x-ray beam which is then processed in the manner described above.

An interstitial X-ray needle includes an elongated X-ray tube coupled to an electron emitter at one end of the tube, with a converter element being disposed at a tip of the other end of the tube for converting emitted electrons into X-ray; a solenoid coil wound around the tube for providing a magnetic field that confines the emitted electrons within a narrow beam; an elongated outer casing enclosing the tube and coil; and a pipe coaxially disposed between the casing and the tube for defining an inner annular flow chamber between the tip of the tube and a coolant inlet in the casing and an outer annular flow chamber between the tip of the tube and a coolant outlet in the casing.

A self-contained hermetically sealed foil changer for advancing a portion of foil web into a position normal to the path of a high energy particle beam. The path of the beam is defined generally by an aperture plate and cooperating axially movable barrel such that the barrel can be advanced toward the plate thereby positioning a portion of the foil across the beam path and sealing the foil between the barrel and the plate to form a membrane across said beam path. A spooling apparatus contained in the foil changer permits selectively advancing a fresh supply of foil across the beam path without breaking the foil changer seal.
