Abstract: In a radiation source and a method for the generation of X-radiation, a liquid is arranged in a liquid line, the liquid being completely surrounded by the liquid line in the direction of an evacuated chamber. A portion of the liquid line is permeable to an electron beam such that the electron beam extending through the chamber is able to enter via the liquid line so as to interact with the liquid in an interaction zone for the generation of X-radiation. The radiation source ensures a good dissipation of heat from the interaction zone and prevents liquid from entering the chamber.

Abstract: A microminiature X-ray tube with a triode structure using a nano emitter is provided, which can increase a field emission region as much as possible by means of nano emitters fine-patterned in a cathode to not only increase an emission current per unit area as much as possible but secure high electrical characteristics, reliability, and structural stability by means of a cover and a bonding material. In addition, gate holes having a macro structure can be formed in the gate to promote electron beam focusing by means of the gate without using a separate focusing electrode and to prevent a leakage current from occurring on the gate. Further, an auxiliary electrode can be formed on a top or an inner surface of a cover applied for structural stability to further promote the electron beam focusing and to control the output amounts per individual X-ray tubes output according to current switching to be equal to each other.

Abstract: The present invention is made to provide an extreme ultraviolet light source target or an X-ray source target having a good operationality. An extreme ultraviolet light source target in accordance with an aspect of the present invention is obtained by including a heavy metal such as tin into a matrix made of a polymeric material such as hydroxylpropylcellulose (HPC). The target can be manufactured by mixing the heavy metal and the polymeric material with a solvent, and evaporating the solvent. Since the target uses the polymeric material as a matrix, the target can be easily deformed to have a desired shape. For this reason, the target can be easily attached to a target holder irrespective of the shape of the holder, resulting in a good operationality of the target. Furthermore, an emission efficiency can be improved by including the heavy metal at a low density.

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.
