High-field split solenoids requirements for beamline applications have become increasingly demanding and an area of significant development in magnet engineering. A number of new magnet designs have been developed utilizing the high current density achievable in modern Nb3Sn superconductors. The magnets described are custom designed for individual experimental applications and have unique...
In this presentation, the concept of a Hybrid Trapped Field Magnet Lens (HTFML) is described, which exploits two different characteristics of type II superconductors: the “vortex pinning effect” of an outer superconducting bulk cylinder, which acts as a trapped field magnet (TFM) using field-cooled magnetization (FCM), combined with the “diamagnetic shielding effect” of an inner bulk magnetic...
Combined with the design of magnetic properties measurement structure and high frequency transformer, the traditional copper stranded wire windings increase the design demand of the core window area to limit the improvement of measuring device. The kind of winding has many turns leading to an increase in inductance. In this paper, an improved windings design method is proposed to optimize the...
An MgB2 superconducting magnet for X-band (12 GHz) Klystrons has been designed, manufactured and tested. According to a CLIC-380GeV staging scenario at CERN, about 5000 sets of klystrons will be used. The Klystrons need electron beam focusing solenoid magnets, and the power consumption of 5000 magnets using Cu conductor is estimated to be 100 MW in case. This MgB2 superconducting solenoid...
This article investigates the main parameters influencing the joint strength of tubular components by electromagnetic compression, more specifically interference-fit (force-fit) by crimping tubes into mandrels. The mechanical parameters considered in this analysis are the remaining residual stress on the mandrel, the joining area and its shape, and the interfacial friction coefficient between...
Stirring casting is one of the most commonly used fabrication processes for particle-reinforced aluminum matrix composites (PRAMCs). It includes mechanical stirring and electromagnetic stirring. Compared with the former, electromagnetic stirring has advantages of non-contact, flexible force loading and so on. However, the structure of traditional electromagnetic stirrer (EMS) is similar to the...
This paper deals with the design and fabrication of a laboratory electromagnet utilizing high temperature superconducting (HTS) coils which is applied to excitate high magnetic fields compared with the conventional laboratory electromagnet with copper coils. The proposed electromagnet was composed of iron-core, HTS coils, and cryostat for the HTS coils. The components are designed using...
This work was performed as part of the international Project 8 collaboration. The goal of the Project 8 experiment is to measure the absolute neutrino mass using tritium beta decays, which involves precisely measuring the energies of the beta-decay electrons in the high-energy tail of the spectrum.
To achieve its design sensitivity of $m_\beta\sim$ 40 meV, Project 8 has chosen an...
Usually, the electromagnetic trip unit in AC circuit breaker has only one trip current value. When a current in circuit is greater than the trip current, the electromagnetic trip unit will be released, so it is suitable for instantaneous tripping in the case of short circuit. In this paper, a novel electromagnetic trip system with two trip current values is studied, which is suitable for...
Induction heating is essentially the use of electromagnetic induction in the conductor of eddy current heating to achieve the purpose of heating the workpiece, with fast, clean, convenient for surface and local heating, and in most cases energy-saving advantages. Compared with the traditional AC induction heating process, the superconducting DC induction heating device uses superconducting...
This paper introduces a novel method of frequency measurement of terahertz (THz) wave with the high magnetic field technology. According to the Zeeman Effect, the magnetic field and frequency are linear, so we can convert the measurement of frequency into the measurement of magnetic field strength by this method. Two magnet systems were used in the experiment, one of them is a pulse magnet...
