UHV Variable Attenuators. Mega Industries specializes in manual and motorized waveguide variable attenuators for use in high power, UHV applications.
Mega Industries produces an array of Ultra High Vacuum (UHV) compatible waveguide and coaxial components that are custom tailored to provide the high electrical performance in the Ultra High vacuum environment down to 1 x 10-12 Torr. That means all of these components are constructed using vacuum rated materials such as OFHC copper, non-magnetic stainless steel (304, 316L & 316LN), and ceramics such as alumina, sapphire and quartz. Our manufacturing process uses advanced vacuum brazing techniques, and all components are cleaned, assembled and tested in our clean room facility.
Mega can test and verify many UHV Variable Attenuator properties such as vacuum He leak rates down to 1.0 x 10-9 Torr l/s, and internal outgassing levels to 1.0 x 10-12 Torr l/s cm2 to deliver “UHV” clean components that can easily be integrated into your systems. Mega will perform bake out procedures and unique vacuum packaging protocols to ensure the components to be in a “vacuum ready” state.
The standard UHV level testing is:
1.0 x 10-6 Torr l/s for larger aluminum (WR650) parts or anything with elastomer seals.
1.0 x 10-9 Torr l/s for UHV (Standard).
Note: 1 Torr = 1.33mBar
Mega has designed and constructed many UHV Variable Attenuators date, each with unique characteristics and properties. Please examine the array of devices Mega’s vacuum experience has developed.
