    Diamond dielectric laser accelerators (DLA) show promise for future applications. Researchers found diamond gratings achieve three times higher acceleration gradients than silicon, paving the way for more powerful particle accelerators.

    Area of Science:

    • Accelerator science
    • Laser-driven acceleration
    • Dielectric laser accelerators (DLA)

    Background:

    • Dielectric laser accelerators (DLA) are a rapidly developing field.
    • Silicon-based structures are currently prevalent due to material properties and processing.
    • A higher damage threshold material is needed for improved performance.

    Purpose of the Study:

    • To investigate diamond as an alternative material for dielectric laser accelerators.
    • To compare the performance of diamond gratings against silicon gratings.
    • To explore the potential for higher acceleration gradients using diamond.

    Main Methods:

    • Fabrication of diamond gratings for DLA.
    • Experimental testing of acceleration gradients.
