Abstract: Provided is an X-ray generator comprising a cathode for generating electrons; a rotating anode having a cylindrical electron impingement surface, an X-ray focal point being formed by a region in which the electrons impinge upon the electron impingement surface; and a Wehnelt electrode for imparting an electric field to the electrons emitted from the cathode. The Wehnelt electrode has a field formation surface for forming the electric field, and an electron passage aperture formed by the field formation surface. The field formation surface of the Wehnelt electrode is inclined with respect to a plane tangent to an outer circumferential surface of the rotating anode at the center of the X-ray focal point. The center of the cathode is in a plane orthogonal to the field formation surface and aligned with the center of the electron passage aperture.

Abstract: A compact apparatus can form multi-X-ray beams with good controllability. Electron beams (e) emitted from electron emission elements (15) of a multi-electron beam generating unit (12) receive the lens effect of a lens electrode (19). The resultant electron beams are accelerated to the final potential level by portions of a transmission-type target portion (13) of an anode electrode (20). The multi-X-ray beams (x) generated by the transmission-type target portion (13) pass through an X-ray shielding plate (23) and X-ray extraction portions (24) in a vacuum chamber and are extracted from the X-ray extraction windows (27) of a wall portion (25) into the atmosphere.

Abstract: A flexible ionizer uses soft X-ray and has a head unit generating soft X-ray whose wavelength is 1.2˜1.5 Å, a soft X-ray protect unit shielding the leak of the soft X-ray from the head unit, and a power control unit supplying a control signal and control voltage to the head unit. The head unit is positioned outside of the soft X-ray protect unit with the flexible ionizer further having a flexible tube protecting a high voltage cable that connects the head unit and power control unit from external impact or vibration and letting the user bend the head of the head unit at an arbitrary angle toward a charged body if necessary, a connecting device letting the ions generated at the window positioned inside of the body of the ionizer emit toward the charged body by connecting one end of the flexible tube and the head unit, and a connecting device connecting the other end of the flexible tube and the body of the ionizer. The high voltage power lines in the flexible tube are molded to prevent short circuits occurring at a near distance between the high voltage power lines and mutual induction voltages occurring. The short circuit and the mutual induction voltage are caused by the mutual influence of the high voltage lines.

Abstract: Air cooled x-ray generating apparatus is provided with a unitary vacuum enclosure having a rotating anode target and a cathode assembly for generating x-rays. The cathode assembly may be placed within the vacuum enclosure through an opening in the top wall thereof, and comprises a disk which completely covers this opening. The unitary vacuum enclosure and the disk form a radiation shield. A plurality of fins are disposed on the exterior side wall of the vacuum enclosure, and a shroud is attached to the fins to provide additional protection of ambient against radiation. The cathode assembly may be placed through a side wall of the vacuum enclosure. The additional protection against excessive radiation in this design is provided by a shielding member placed in proximity to the anode target. The shielding member extends from the side wall of the enclosure and is substantially parallel to the top wall.
