The MKS Astron 2L (specifically the AX7657) is a remote plasma source used primarily in semiconductor manufacturing for chamber cleaning and reactive gas generation. Because these are specialized industrial components, a formal "user manual" is often protected by MKS proprietary rights, but you can find technical specifications and operational overviews through industrial resellers and technical support platforms. Quick Technical Summary
to produce atomic fluorine for high-efficiency chamber cleaning. Input Power: Typically 180–228 VAC, 3-phase, 50/60 Hz. Gas Requirements: Ignition: Requires 100% Argon ( Process: Supports up to 3.0 slm of Nitrogen Trifluoride ( NF3cap N cap F sub 3 Operating Pressure: During Ignition: 1 to 4 Torr. Post-Ignition: 1 to 10 Torr.
High-flow water cooling is generally required for these high-power RF units Springer Nature Link Safety & Maintenance (from the Manual) Pressure Warning: mks astron 2l manual
The MKS ASTEX Astron 2L is a high-performance Remote Plasma Source (RPS) primarily used in semiconductor manufacturing for chemical vapour deposition (CVD) chamber cleaning. Its primary function is to generate atomic fluorine by dissociating input gases like Nitrogen Trifluoride ( NF3cap N cap F sub 3
While the Astron 2L is often praised for its massive build volume and enclosed design, understanding the nuances of its operation is key. This post serves as your practical "manual"—a guide to setting up, running, and maintaining your Astron 2L so you can cure your prints safely and effectively.
