    Abstract: The present invention provides a system and method of predicting the initial cooling of a superconducting magnet, which can predict the change in initial cooling temperature of a superconducting magnet when the superconducting magnet is cooled using an ultra-low refrigerator. In the system and method, the change in cooling temperature of a superconducting magnet can be accurately predicted by classifying influence factors related to the cooling of a superconducting magnet into a plurality of control volumes and inducing a governing equation with respect to each of the control volumes. Based on this system and method, the reliability of basic data required to design an apparatus for measuring a high magnetic field for forming an ultralow-temperature environment can be greatly improved.

    Abstract: Surface measurement data just provides the coordinates of an object surface without giving various parameters like the radius of curvature, conic constant, and deformation coefficients. In this paper, we propose a novel method for extracting the important parameters for the determination of unknown aspheric surface equations from the measurement of aspheric surfaces. The largest error between the original surface and the reconstructed surface in the theoretical case is shown to be about 8.6 nm. This fact implies that the new method is well suited for the reconstruction of unknown surface equations.

    Abstract: An ion trap mass spectrometer is provided, including: an electron emitter; an ion trap storing ions generated by ionization resulting from an impact with electrons emitted from the electron emitter; a secondary ion filter for blocking out secondary ions generated due to ions selectively released by the ion trap; and a detector detecting ions selectively released from the ion trap, wherein the electron emitter, the ion trap, the secondary ion filter, and the ion detector are arranged on the same axis, so that a pure mass spectrum can be measured by excluding the secondary ions which are causes of background noise signals in the procedure of detection of the ions by the ion trap mass spectrometer.

    Abstract: The present invention relates to a gaseous sample injection valve. The gaseous sample injection valve includes a middle body injecting a fixed amount of a gaseous sample into the vacuum chamber of a mass spectrometer, the middle body being constituted by a gaseous sample injection tube, a gaseous sample discharge tube, a storage part, and a vacuum chamber connection tube; an upper body accommodating a first solenoid coil, a first plunger, and a first packing; and a lower body accommodating a second solenoid coil, a second plunger, and a second packing. The gaseous sample injection valve according to the present invention may be miniaturized to utilize a lightweight portable mass spectrometer. Also, the vacuum pump may be reduced in load to extend the operation life-cycle of the vacuum pump. In addition, when the gaseous sample is analyzed by using the mass spectrometer, a uniform mass spectrum with respect to the gaseous sample may be obtained.
