The scheme that the sharp pulse disturbance filter consists of the magnetic core inductor and feed-through capacitor is proposed. The filter is a sort of LC filter where L represents the inductor with a high magnetic permeability core and little distributive capacitance and C represents a feed-through capacitor with little parasitic inductance. Moreover, the method for designing the filter is given...
In this work, we report a SU-8-based fully integrated miniaturized inductively powered LC transponder for generic implantable wireless sensor applications. It consists of a 1 mm diameter octagonal spiral inductor and a micro fabricated MIM (metal insulator metal) capacitor. Polyvinylidene Fluoride-Trifluoroethylene (PVDF-TrFE) copolymer is applied as a dielectric material for the capacitor fabrication...
The development of pulsed magnets as practical and efficient research instruments is reviewed, from a few notes on early developments to the sophisticated high performance magnets that are in use nowadays. This includes a review of magnet laboratories that are now in operation. The distinction is made between non-destructive, semi-destructive and destructive magnets, with emphasis on ldquouserrdquo...
A new facility for experiments in pulsed high magnetic fields up to 80 T is under construction at the Huazhong University of Science and Technology (HUST) in Wuhan, China, funded by the National Development and Reformation Committee (NDRC). The pulsed power supplies are a modular 12 MJ/25 kV capacitor bank and a 100 MW/100 MJ flywheel pulse generator, and most of field coils are energized by the capacitor...
Wuhan pulsed high magnetic field facility is under development. Magnets of bore sizes from 12 to 34 mm with the peak field in the range of 50 to 80 T have been designed. The pulsed power supplies consists of a 12 MJ, 25 kV capacitor bank and a 100 MVA/100 MJ flywheel pulse generator. A prototype 1 MJ, 25 kV capacitor bank is under construction. Five magnets wound with CuNb wire and copper wire reinforced...
This paper presents an approach for the evaluation of the instantaneous transverse magnetic field (TMF) in the inter electrode space of a Walkie Edgar type spark-gap device. The method has been integrated into a time marching routine to enable studies of arc velocity variation in the device. The analysis shows that the TMF and hence the arc velocity vary over the peripheral length of the device. The...
