In an x-ray preionised XeF(B~X) dischargeexcited laser driven by a magnetic-spiker sustainer circuit with a magnetic pulse compressor the influence of the various parameters on the optical pulse duration was experimentally investigated. Laser pulses at 2= 351 nm with a duration of 212 ns (FWHM) have been achieved in a NF3/Xe/Ne mixture by using very low (0.25 mbar) NF3 partial pressures in a to...

Linear motors are strong candidates in electromagnetic launching technology for space-use. In this paper, two types linear motors, including parallel magnetic circuit linear permanent magnet brushless DC motor (PMC-LPMBDCM) and serial magnetic circuit linear permanent magnet brushless DC motor (SMC-LPMBDCM), have been presented for electromagnetic catapult. The rudimental configurations of thes...

This paper presents two methods for determining the complex antenna factor (CAF) of a shielded loop antenna for HF magnetic field measurements. A circuit model is introduced to apply the field-transferred 3-antenna method to double-loaded shielded loop antennas. In addition, a new 3-antenna method is proposed, where theoretical calculation and circuit measurement are combined. Experiments are m...

We develop a theory for the quantum circuit consisting of a superconducting loop interrupted by four Josephson junctions and pierced by a magnetic flux (either static or time-dependent). In addition to the similarity with the typical three-junction flux qubit in the double-well regime, we demonstrate the difference of the four-junction circuit from its three-junction analogue, including its adv...

AbstructOne-dimensional parallel arrays of Josephson junctions have the ability to perform as oscillators tunable hy magnetic flux. We have designed and tested an array impedance matched to a detector junction load. The amplitude and frequency of the array are controlled by the independent variables of magnetic field and current bias. We report on the array's characteristics and compare them to...

MOS devices go 3D, new quantum effect devices appear in the research labs. This paper discusses the impact of various innovative device architectures on circuit design. Examples of circuits with FinFETs or Multi-Gate-FETs are shown and their performance is compared with classically scaled CMOS circuits both for digital and analog applications.

In this work, approximate formulas are presented for computing the magnetic field intensity near electric power transmission lines. Original expressions are given for single circuit lines of any type of arrangement and double circuit lines in both super-bundle and low-reactance conductor phasing. These expressions can be used for assessing directly the Right-of-Way width of power lines related ...
