Key Features
-
Bespoke Design Solutions: Fully customizable geometries, dimensions, and sealing configurations to meet unique operational requirements, including tailored electrode positioning, port placements, and beam path alignment.
-
Advanced Glass-Alloy Construction: Engineered with proprietary glass-metal hybrid materials, offering exceptional thermal shock resistance, minimal outgassing, and compatibility with ultra-high vacuum (UHV) conditions.
-
Hermetic Sealing Excellence: Precision glass-to-metal or glass-to-ceramic seals ensure leak-proof performance (helium leak rate ≤1×10⁻¹¹ mbar·L/s), even under extreme thermal cycling (-50°C to +500°C).
-
High-Energy Compatibility: Optimized for X-ray, electron beam, or ionizing radiation applications, with shielding options to minimize electromagnetic interference (EMI) and parasitic currents.
-
Nanoscale Precision: Sub-micron tolerances (±0.05mm) and ultra-smooth internal surfaces to maximize beam focus efficiency and minimize particle contamination.
Applications
-
Medical Imaging: X-ray tubes for CT scanners, radiotherapy systems, and diagnostic equipment.
-
Industrial Non-Destructive Testing (NDT): High-energy beam sources for material inspection, weld analysis, and aerospace component evaluation.
-
Scientific Research: Particle accelerators, synchrotron radiation devices, and vacuum chamber instrumentation.
-
Semiconductor Manufacturing: Electron beam lithography and ion implantation systems.

Customization Options
-
Material Pairings: Kovar, Invar, or stainless steel interfaces for thermal expansion matching.
-
Window Configurations: Beryllium, aluminum, or diamond-coated windows for specific radiation transmission.
-
Cooling Integration: Air- or water-cooled jackets for high-power applications.
-
Certifications: Compliance with ISO 13485 (medical), MIL-STD-810 (aerospace), or IEC 60601 standards.
Quality Assurance
Every assembly undergoes rigorous validation:
-
High-voltage arcing tests (up to 200 kV).
-
Residual gas analysis (RGA) for vacuum purity.
