Comment: This is a lightly reworded version of an originally LLM-generated draft; merely rewording LLM-generated text usually does not resolve the problem of LLM usage. Please remove all text (while keeping the review template) and start over without LLMs. For general advice, see Help:Your first article. Helpful Raccoon (talk) 07:52, 24 September 2026 (UTC)

Steady-state microbunching (SSMB) is a proposed approach to create synchrotron radiation light with both high brightness and coherence.[1]
accelerator-based Synchrotron light source architecture designed to generate high-average-power, continuous-wave (CW) Extreme ultraviolet (EUV) light. To overcome the temporal incoherence of conventional storage ring and the low duty cycles of pulsed linear Free-electron laser (FEL), SSMB synthesizes the strengths of both systems to achieve highly coherent radiation at megahertz repetition rates. It achieves this by utilizing an external high-power laser modulator and magnetic elements to organize a continuously circulating electron beam into regularly spaced, longitudinal microbunches at optical or EUV wavelengths. This externally maintained, periodic structure allows the electrons' electromagnetic fields to add coherently as they pass through an undulator.[2][3] The primary application for SSMB is multi-kilowatt, 13.5 nm wavelength demands of next-generation high-numerical-aperture (High-NA) semiconductor lithography for sub-3 nm logic nodes. SSMB can achieve average powers exceeding 1 kW, which aims to bypass the physical scaling limitations and theoretical ~500 W ceiling of current laser-produced plasma (LPP) sources. First theorized in 2010 and successfully demonstrated at the Metrology Light Source (MLS) in Berlin in 2021, the technology is now being scaled toward kilowatt-class viability, notably through a Tsinghua University-led prototype facility under construction in Xiong'an New Area, Hebei, China.[3][4]

Please delete the portions which were LLM-generated, and summarize in your own words a range of independent, reliable, published sources that discuss the subject. If you have used an LLM but you believe that your use is covered by one of the two exceptions (basic copyediting and translation between two languages in which you are fully fluent), please provide a transcript of the prompt(s) you used while writing your draft (see the how-to guide). Reviewers can make mistakes. If you have not received any LLM assistance, you may seek a second opinion at the AfC Help Desk.
