Generating Electromagnetic Radiations01:10

Generating Electromagnetic Radiations

2.9K
The German physicist Heinrich Hertz (1857–1894) was the first to generate and detect certain types of electromagnetic waves in the laboratory. Starting in 1887, he performed a series of experiments that confirmed the existence of electromagnetic waves and verified that they travel at the speed of light. Hertz used an alternating-current RLC (resistor-inductor-capacitor) circuit that resonated at a known frequency and connected it to a loop of wire. High voltages induced across the gap in...

Transmission Electron Microscopy

5.5K
In 1931, physicist Ernst Ruska—building on the idea that magnetic fields can direct an electron beam just as lenses can direct a beam of light in an optical microscope—developed the first prototype of the electron microscope. This development led to the development of the field of electron microscopy. In the transmission electron microscope (TEM), electrons are produced by a hot tungsten element and accelerated by a potential difference in an electron gun, which gives them up to 400...

    • Physics
    • Engineering
    • Materials Science

    Background:

    • Compact electron sources are vital for physics, medicine, and industry.
    • Terahertz (THz)-driven electron manipulation shows promise for high-gradient acceleration in dielectric-lined waveguides (DLW).
    • Previous methods using THz surface waves achieved high THz energy but suffered from large electron energy spread.

    • To overcome the limitations of large energy spread in laser-induced electron pulses.
    • To develop a more practical and efficient THz-driven electron source.

    Main Methods:

    • Proposed a scheme extending THz surface-wave concepts to commercial electron guns.
    • Utilized a simple hollow cylinder tube for electron transmission.
    • Employed a 2.9 mJ single-cycle terahertz pulse for electron manipulation.

    Main Results:

    • Achieved significant electron energy modulation up to 860 keV.
    • Demonstrated electron pulse width compression to 15 femtoseconds (fs).
    • The hollow tube design facilitates cascading the system for enhanced performance.

    Conclusions:

    • The proposed scheme effectively modulates electron energy and compresses pulse width using mature electron sources.
    • The hollow tube design offers a practical pathway for compact and efficient THz-driven electron sources.
    • This advancement is expected to significantly impact fundamental physics, oncology, and advanced industrial applications.
