摘要： PROBLEM TO BE SOLVED: To provide a beam current attenuator easily manufactured and capable of easily adjusting a beam current of charged particle beams.
SOLUTION: This beam current attenuator 1 is provided with a metal plate 2 provided with a plurality of slits 4, and a supporting shaft 3 supporting the metal plate 2 and movable reciprocating in an axial direction. A plurality of slits 4 are provided at the metal plate 2 parallel with one another, and the width dimension of the slits 4 is continuously reduced toward the supporting shaft 3 along the longitudinal direction. Consequently, when the metal plate 2 is irradiated with the charged particle beams 5, the charged particle beams 5 pass through only the slits 4 but do not pass through other metal parts. The beam current can thereby be attenuated, and the width dimension of the slits 4 is changed by reciprocating the metal plate, thus changing the attenuation factor of the beam current.

摘要翻译：要解决的问题：提供容易制造并能够容易地调节带电粒子束的束电流的束流衰减器。解决方案：该束流衰减器1设置有设置有多个狭缝4的金属板2和支撑金属板2并沿轴向往复运动的支撑轴3。多个狭缝4彼此平行地设置在金属板2处，并且狭缝4的宽度尺寸沿着纵向方向朝着支撑轴3连续地减小。因此，当金属板2被带电粒子束5照射时，带电粒子束5仅穿过狭缝4但不通过其它金属部件。射束电流因此可以被衰减，并且通过使金属板往复运动来改变狭缝4的宽度尺寸，从而改变束电流的衰减系数。

摘要： PROBLEM TO BE SOLVED: To provide a radiation detector that efficiently condenses light which has passed through scintillation fibers on the side opposite a photomultiplier tube onto the photomultiplier tube and reduce the variations in detection sensitivity due to the distance between a radiation incident position and the photomultiplier tube. SOLUTION: The radiation detector uses the scintillation fibers 1 which emit fluorescence, in response to the incident of radiation and are arranged in a planar manner. The radiation detector comprises U-shaped, and strip-shaped arrangement parts (2, 3) which consist of the scintillation fibers, having two parallel linear parts and U-shaped folded parts which couple one ends of the linear parts to each other and the photomultiplier tube (7) which is optically coupled to the other ends of the linear parts of the U-shaped, strip-shaped arrangement parts.

摘要： PROBLEM TO BE SOLVED: To provide an image processing system capable of precisely analyzing the characteristic amount of an image even if an image input means or a subject to be imaged is damaged by radiation when the system is used in a radiation environment, thus ensuring a long life as to radiation-induced degradation. SOLUTION: An image of a fluorescent plate 2 not irradiated with a beam 1 is picked up using a camera 4 and a background brightness distribution 10 formed by processing the image using an image processing means is stored. An image of the fluorescent plate 2 with a luminous image 3 formed thereon by the beam 1 is picked up using the camera 4. The image of the fluorescent plate 2 picked up using the camera 4 is processed by the image processing means to form a twodimensional brightness distribution 6 corresponding to the luminous image 3. Also, using the previously stored background brightness distribution 10, defective pixels 7 in the two-dimensional brightness distribution 6 corresponding to the luminous image 3 are corrected and the characteristic amount of the luminous image 3 is extracted.

摘要： PROBLEM TO BE SOLVED: To form an efficient effective magnetic field region corresponding to charged particle beam width and to accurately set an edge angle as occasion demands by changing stacking structure of electromagnetic steel plates. SOLUTION: This deflecting electromagnet sets an edge angle α by inclining electromagnetic steel plates 2a, 2b in charged particle beam outlet and inlet 6A, 6B of an electromagnet main body 1 by a specified angle to the perpendicularly crossing surface with the beam axis of a charged particle beam 7, other electromagnetic steel plates are stacked so as to match with a designed orbit 8 through which the charged particle beam is passed by shifting one by one in parallel to the electromagnetic steel plates 2A, 2B in the charged particle beam outlet and inlet 6A, 6B, and thereby, magnetic pole width H is made wider in the central part of the designed orbit 8 than the charged particle beam outlet and inlet 6A, 6B sides.
