Description of Beryllium CF Flange Window Assemblies
A beryllium window is a type of window made of beryllium material, which has excellent X-ray penetration and other physical properties. Beryllium windows are widely used in X-ray equipment, mainly for windows in X-ray tubes, detectors, and low-energy photon sources. Its excellent X-ray penetrability makes beryllium windows have important applications in medical diagnosis and treatment, industrial non-destructive testing, structural analysis, spectral analysis, and film exposure.
Beryllium CF Flange Window Assemblies are a commonly used window material in the field of medical imaging. Beryllium CF Flange Window Assemblies have the advantages of low atomic coefficient, high stability, high ray transmittance, strong corrosion resistance, and high temperature and pressure resistance. The low uptake of the Beryllium Window limits the warming effects of the high-power, low-energy x-ray beam, providing constant transmission across the window.
Beryllium CF Flange Window Assemblies have high moisture resistance, chemical resistance, and abrasion resistance, which can ensure that they remain vacuum-tight in harsh operating environments, and are widely used in imaging, diagnostic, and laser applications in the medical industry, homeland security imaging equipment.
Features Of Beryllium CF Flange Window Assemblies
Extremely Low Mass Absorption: Beryllium (Z=4) is lighter than many materials, with a density of 1.85 g/cm³. Moreover, beryllium's transmittance surpasses that of aluminum or quartz for SX and neutron beams. This enables reduced beam attenuation just with a window thickness of 0.1-0.5 mm, which can achieve over 80% transmittance.
Ultra-High Vacuum Compatibility: Beryllium's transmittance surpasses quartz and aluminum for SX and neutron beams. This enables reduced beam attenuation just with a window thickness of 0.1-0.5 mm, which can achieve over 80% transmittance. The structure of a CF knife-edge flange with 316L Stainless Steel bonded to a Be disc via metal diffusion or silver-copper brazing creates an all-metal seal. In addition, the seal is capable of withstanding high-temperature bakeouts of 450°C, which is of advantage when achieving an ultimate vacuum of < 1 ×10-11 mbar and eliminating the risk of rubber outgassing.
Airtightness and Pressure Resistance: The disc is rated to have a post-weld edge leak rate of <1×10−10 Pa·m³/s with a 1 bar pressure differential. Moreover, the beryllium disc can be reinforced with a stainless steel honeycomb or mesh for increased pressure resistance and less reduction to the light transmissive area. Beryllium is thermally stable, with a coefficient of expansion that matches that of the brazing alloy, which ensures welds stay intact for 1000 cycles of 200°C is hot. Shelving is also extended with a 50 nm coating of anti-oxidation with Al₂O₃ or Parylene-C.
Applications Of Beryllium CF Flange Window Assemblies
Synchrotron radiation and free electron lasers: Act as X-ray exit windows in back-end vacuum pipelines, enduring high power beam currents and preserving beamline ultra-vacuum conditions.
Semiconductor inspection equipment: Act as vacuum chamber windows for X-ray lithography (EUV/XRL), permitting precision alignment and defect identification.
Neutron scattering devices: Serve as neutron guide end windows and detector entrance windows, providing low absorption and high voltage resistance.
Electron beam/ion beam systems: Serve as observation windows and beam diagnostic windows in high vacuum chambers to shield from magnetic fields.
