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:
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:
Disclosed is an aluminum-polymer resin composite. The composite includes i) aluminum and ii) a polymer resin bonded to the aluminum after modification of the aluminum surface with at least one surface modifier selected from the group consisting of sulfur-containing diazole derivatives, sulfur-containing diamine derivatives, sulfur-containing thiol derivatives, sulfur-containing pyrimidine derivatives, and sulfur-containing silane coupling agents. The intensity ratios of C/Al, N/Al, O/Al, Na/Al, Si/Al, and S/Al in the composite are in the range of 9.75×10−6 to 9.5×10−1 at depths of 100 nm to 500 nm, as analyzed by secondary ion mass spectrometry (SIMS). The composite has improved adhesive strength between the metal and the resin while maintaining its tensile strength and air tightness even after thermal shock testing. The composite is produced through various processing steps, including pretreatment, appropriate surface roughening, thermal treatment and surface coating, to enhance the bonding strength between the metal and the resin. The use of compounds containing S, N and Si further increases the bonding strength between the metal and the resin.
