 Beamtek Beryllium Window For Synchrotron Radiation

▪   Vacuum-tight windows can be used to isolate an ultrahigh vacuum (UHV) synchrotron beamline from the equipment of an experimenter operating in a non-UHV environment. A thin beryllium plate mounted on a vacuum flange can be used as a high transmission window/filter for experimenters using synchrotron radiation in the X-ray region.



Beamtek Beryllium Window
    ▪High transmissivity to x-rays.
High melting point.
High thermal conductivity.
Low electrical resistivity.
Very low specific heat at cryogenic temperatures.
Very high specific heat at normal and elevated temperatures.
Very low neutron capture cross section.

Technical pecifications
  • Window material
  • The beryllium foil is the vacuum tight IF-1 type, purity of 99.8% beryllium assay minimum by specification.
  • The flanges and the tubes are 304L stainless steel.
  • The cooling plate is OFHC copper. 
  • Surface finishes
  • The Beryllium foil is 0.1um Ra polished finish or better on both side surfaces. 
  • Windows fabrication tolerances
  • All beryllium window dimensions carry a ±0.5 mm linear and ±0.5° angular tolerance. 
  • Cleaning
  • All cleaning processes of the beryllium windows shall meet UHV requirements. 
  • Leak testing on both side of the window flanges
  • The beryllium windows are leak tested using helium mass spectrometer to no leak greater than 2×10 -10 mbar‧l/s leak rate.
  • Operating Conditions
  • Vacuum range:< 2×10-10 Torr
  • Temperature range:10℃ to 150℃ 
  • Vacuum brazing and diffusion bond
  • ALL vacuum tight joints on the assemblies are made by vacuum braze or diffusion bond and are guaranteed bake able to 450°C.
