Abstract: PURPOSE:To do focusing efficiently and to improve a filter function of the mirror, by forming the mirror shape for focusing radioactive rays as an inner shape of a revolving member which has a larger revolving radius as the distance from the radioactive ray source is larger toward a sample. CONSTITUTION:Synchrotron radiation light (SOR light) from a generating source diverges in a fan shape with an opening angle 2beta in a horizontal plane, but does not almost diverge in a vertical plane. A mirror 12 for focusing parallel the SOR light is shaped as a coniform inner shape which has a larger radius as the distance from the radioactive ray source 11 is larger toward a sample. A coniform apex angle 2alpha is selected so that viewing angles of outmost rays 13, 14 and central rays 15 of the SOR light to the mirror 12 become both theta. Thus variation of the viewing angle theta becomes very small over a wide range of incident positions of the SOR light to the mirror 12, and a focusing function of the mirror 12 and a filtering function can be improved.

Abstract: PURPOSE:To send current similar with an input voltage waveform and keep the output electric power constant by detecting the alteration of the effective value of an input a.c. voltage and correcting the standard bias based on the detected signal. CONSTITUTION:The output signal from an output terminal OUT of a switching control IC 28 is integrated in a time constant circuit for integration composed of resistors 36, 38 and a capacitor 37 and in the case the effective value of the input voltage lowers and the duty ratio of the output control signal of the IC 28 becomes high as a whole, the integration value becomes high and to the contrary, in the case the duty ratio becomes low, the integration value becomes low. The integration value is subtraction-processed by the standard bias determined by bias adjusting resistors 24, 2 5 and a computation amplifier 35. The resultant output is sent to a computation amplifier 21 as a bias component and, together with the current detected value of a switching device 12, it is subtraction-processed and further after compounded with a triangular wave, it is sent to a current detecting terminal ISENS of the IC 28. As a result, high power efficiency is achieved and at the same time the output electric power is made to be constant.
