Product Specifications

Titanium UHV Sealing for Aluminum Chambers

The Atlas Bimetal Ti/Al CF Flange with aluminum flange body bonded to rugged titanium uses the time-tested reliability of the ConFlat® (CF) knife-edge seal. After welding the CFTA™ flange to an aluminum vacuum chamber, it becomes a completely non-magnetic UHV chamber. This supports applications where high magnetic permeability is detrimental to beam quality or experimental results. 

Non-magnetic aluminum vacuum chambers are used for UHV synchrotron, particle physics, and industrial applications where high magnetic permeability is detrimental to beam quality or experimental results. Such applications include non-magnetic beam tubes, wigglers, undulators, free electron lasers (FEL), drift tubes, and spectrometers.


Applications:

  • UHV synchrotron
  • Particle physics 
  • Semiconductor fabrication
  • Industrial applications
  • XHV quantum physics 
  • Beam tubes
  • Wigglers and undulators 
  • Free electron lasers (FEL) 
  • Drift tubes
  • Spectrometers

Low Z, Low Nuclear: Atlas titanium-aluminum flanges enable aluminum UHV systems to be used in demanding nuclear applications requiring a low z environment.

  • Cyclotrons 
  • Nuclear reactors
  • Medical imaging

Light/Low Weight: With weight-to-volume ratios 1/3 that of stainless vacuum chambers, an aluminum chamber with Ti/Al flanges significantly reduces overall weight:

  • Aerospace  
  • Portable systems
