Abstract:
PURPOSE: An X-ray spectrometer system for nuclear fusion plasma diagnosis is provided to correct a horizontally polarized X-ray image crystal spectrometer and a vertically polarized X-ray image crystal spectrometer at a time. CONSTITUTION: An X-ray spectrometer system for nuclear fusion plasma diagnosis includes a first X-ray image crystal spectrometer and a second X-ray image crystal spectrometer. The first X-ray image crystal spectrometer includes a first spherical surface crystal and a first detector. The first spherical surface crystal(20) horizontally reflects an X-ray generated from plasma of a nuclear fusion plasma generating device(1). The first detector(10) detects the X-ray reflected in the first spherical surface crystal. The second X-ray image crystal spectrometer includes a second spherical surface crystal and a second detector. The second spherical surface crystal(200) vertically reflects the X-ray generated from the plasma of the nuclear fusion plasma generating device. The second detector(100) detects the X-ray reflected in the second spherical surface crystal.

PURPOSE: A plasma probe assembly is provided to draw a signal line out by a shielding member, thereby arranging a probe unit without respect to a coolant path of a fixing frame. CONSTITUTION: A probe unit is attached/detached to/from a fixing supporting member of a fixing frame fixed to the inside of a vacuum container of a tokamak. The probe unit includes an exposure unit which senses a physical parameter of plasma. A shielding member(50) shields the parts except for the exposure unit. The probe unit comprises an insulation supporting member(31), a probe body(32), and a signal line(34). The signal line is connected to the probe body. The signal line is drawn out to the outside through the shielding member.

PURPOSE: A plasma prove driving apparatus is provided to rapidly measure a spacious distribution value of a plasma constant by rapidly moving the plasma prove to an initial location. CONSTITUTION: A driving cylinder(40) is movably mounted on a fixing member(20). A rod of the driving cylinder is driven to moving direction of a probe part. The probe part is arranged on one end of a probe part moving part(50). The other end of the probe part moving part is connected to the rod of the driving cylinder. The probe part moving part moves the probe part with connecting a movement of the rod of the driving cylinder. A driving unit(60) moves the driving cylinder to the moving direction of the probe part in order to move the probe part to the initial location.

A magnetic probe for measuring a high frequency magnetic fluctuation under high temperature, ultra-vacuum and high magnetic field environments is provided to reduce a ratio of an electromagnetic wave noise signal under a high electromagnetic environment. A magnetic probe for measuring a high frequency magnetic fluctuation under high temperature, ultra-vacuum and high magnetic field environments includes a ceramic bobbin(1) and a conductive wire(2). The conductive wire is wound around on the ceramic bobbin. Two spiral grooves with different depths are formed on a surface of the ceramic bobbin. The spiral grooves are formed at positions opposite to each other on a central axis of the ceramic bobbin and are connected with each other at an upper part of the ceramic bobbin. The conductive wire is continuously wound around the ceramic bobbin along the two spiral grooves. Both ends of the conductive wire are placed at a lower part of the bobbin. The conductive wire is a bare wire.

A method for generating a uniform and monochromatic X-ray and an apparatus to generate an X-ray are provided to apply the apparatus to an image needed for high definition and accurate analysis by realizing the uniform and monochromatic X-ray having a large area. In a method for generating a uniform and monochromatic X-ray, the monochromatic X-ray is generated by reflecting an X-ray generated in an X-ray generator(1) to a spherical crystal(2) by using the X-ray generator(1) located on the same rowland circle(3) and the spherical crystal(2) forming a part of an arc of the rowland circle(3). The X-ray is generated by an X-ray tube.

A large-area multi-segmented two-dimensional position-sensitive proportional gas injection type counter includes anode lines(30) and lower and upper cathode lines(20,40). The anode lines and the lower and upper cathode lines are formed by a plurality of metal lines and are arranged at a PCB(Printed Circuit Board). The anode lines and the lower and upper cathode lines arranged at the PCB are sequentially fixed by a frame having a radiational incidence surface. Gas is charged in the frame. The anode lines are connected to a power source. Delay-lines are connected to both ends of the upper and lower cathode lines. At least one of the PCBs with the anode lines and the lower and upper cathode lines is divided into at least two.
