Description
This work presents the development of a collimated electron beam suitable for acceleration in dielectric laser accelerators (DLA). A thermionic electron gun was designed to produce a stable ~0.2 mm beam under high-vacuum conditions with electron energies of 10–47 keV. Beam emission and focusing parameters were optimized to enable reliable injection into compact accelerating structures. To ensure the required vacuum quality, a custom hydrogen-based leak detector was developed and successfully applied to identify and eliminate leakage in the beamline. Additionally, a beam deflection system and diagnostic tools for measuring beam current and electron yield were implemented and tested. The results confirm the feasibility of the proposed solutions and highlight the potential for further advancement of compact accelerator technology.
