Photo-Electron guns require Ultra-High vacuum (UHV)
in order to maximize quantum efficiency and cathode lifetime.
The vacuum levels required for the electron gun exceed the requirements of
any other portion of the CEBAF accelerator.
Extensive research has been performed within the Electron Gun Group to
produce this UHV environment. This research includes:
- Bake temperature vs.
ultimate pressure studies
- Material Outgassing rate studies
- Material coating
studies
- Neg materal
selection and geometry studies
- Ion pump ultimate
pressure studies
