Gyrotron is a promising source of high-frequency, high-power RF radiation for plasma heating, ESR spectroscopy, new medical technology and so on. The magnetic field system, which controls the trajectory of the electron beam and the cyclotron frequency of electrons at the resonator cavity, is one of the key parts of the gyrotron. According to the theory of electron cyclotron masers, an 800 GHz...

We constructed a long and flexible solenoid coil by winding a thin, enameled wire around a slightly thicker enameled wire. The structure of this flexible solenoid resembles that of a string of a guitar or a piano. The flexible solenoid is wound on a torus in toroidal direction.

Due to its high efficiency and uniform deformation force, the uniform pressure actuator (UPA) is a potential electromagnetic forming (EMF) technology for shaping of mesoscale dimensional metals, such as metal bipolar plates. However, because of its complex structure, the current simplified two-dimensional model or three-dimensional model cannot fully reveal the law and characteristics of UPA,...

In order to solve the problem that the traditional gas wiping method cannot meet the needs of high-speed production, the oxidation and atomization of zinc liquid which not only wastes zinc, but also disperses zinc into the air to pollute environment, a three-phase electromagnetic wiping based on traveling wave magnetic field is proposed. By using a three-phase coil, a traveling wave magnetic...

Under the earth magnetic field, ferromagnetic equipments on a naval ship are magnetized, and accordingly they are apt to cause a local field disturbance underwater. To mitigate such magnetic field for ship’s safety, modern vessels are usually equipped with a degaussing system. In order to minimize the underwater field anomaly, individual coil currents are elaborately tuned, and so there are...

REBCO coated conductor has been regarded as one of the most viable high-temperature superconductor (HTS) options for next-generation high field magnets, mainly owing to its large in-field current carrying capacity and higher mechanical strength. To explore REBCO coil technology, a small-scale REBCO coil was designed, fabricated and tested. The REBCO coil has a winding inner diameter of 15 mm,...

We propose a model of the spherical vector-potential coil, and we investigate the properties of the coil especially the uniform distribution of vector potential. The model is designed base on a spherical winding which made by the long flexible thin solenoid. When we apply a current to a very long solenoid coil, it creates a magnetic field within the coil only; there is no magnetic field...

As the pellet injection for the fuel of the Large Helical Device (LHD), a pneumatic pellet injection is generally used. Although this method injects some pellets made of frozen hydrogen gas into a plasma of the LHD at the velocity of 1.2 km/s, the pellet does not reach the plasma core. For this reason, this method is not efficient in the fuel supply.
Recently, a novel pellet injection...

In previous studies, the advantages of high temperature superconductor (HTS) DC induction heater (HIH) in energy saving and better heating quality had been provided. Compared with the conventional AC induction heater, the initial capital investment for HIH is high. The energy cost saved in the future is applied to pay the cost of HIH project. The key issue of the industrial application is to...

In this study, a wireless power transfer (WPT) technology with a superconductor was proposed. The proposed technology maximizes efficiency by applying superconducting characteristics to the resonance coil. To maximize the efficiency of the resonance coil during WPT, it is essential to consider the inductance and coupling coefficient (k). They are determined by the shape of the resonance...
