Second report on the experimental progress of the one microsecond one kilojoule per pulse L-band relativistic klystron at Los AlamosAbstract: Work is continuing on a high-current relativistic klystron amplifier (RKA) with the goal of producing 1 kJ per pulse with a 1 $mu@s pulsewidth and a...
aA typical automobile engine has a maximum power output of 200 horsepower. One horsepower is 746 watts. One watt is one joule per second. Assume that a car traveling at 61 mph gets 25 miles per gallon of gasoline using 26% of the maximum power of the engine 一个典型的汽车引擎有200马力...
In a bid to respond to the challenges being faced in the installation of flywheel-based electric energy storage systems (EESSs) in customer-side facilities, namely high safety, high energy/power densities and low cost, research work towards the development of a novel, one-body, laminated-rotor...
respectively. Secondly, the start thiazole derivative7was obtained from the intermolecular cyclization of thiourea, chloroacetic acid,p-nitobezaldehyde in the presence of sodium acetate. We synthesized various derivatives from this second starting compound7by being subjected to different reagents such as ...
Energyis the ability to do work, and it comes in different forms: heat (thermal), light (radiant), motion (kinetic), electrical, chemical, nuclear and gravitational. mg/mm³ to sl/metric c conversion table,mg/mm³ to sl/metric c unit converteror convert between all units ofdensitymeas...
A PFN consisting of two stages (the main energy storage stage and a pulse shaping stage) was evaluated in this study. Each stage generates a different harmonic of the desired waveshape. When the outputs of both stages are added together at the load, the resultant waveform has the desired ...
Energy storage and conversionDeveloping highly efficient anodic catalyst is important, yet still challenging. Here, hybrid catalyst of Pd with multi-metallic oxides (Pd/MMO) was synthesized in one step on commercial carbon black with one-second high-temperature shock through Joule heating. Thanks to...
An effort was made to produce a compact, lightweight, high-energy modulator. The device was to power various low-impedance loads including up to 25 vacuum diodes in parallel. Desired characteristics were a 1 mu s rectangular pulse of 200 kV amplitude into 1 to 2.5 Omega loads. Pulse ...

However, the surge in demand has led to an imbalance between the supply and demand of battery raw materials, which has led to an increasing cost of vehicle manufacture. At the same time, with technological progress and industrial improvement, the new-energy automobile subsidy standards implemented...
