RHEED

  • Fundamental unit of PASCAL Reflection High-Energy Electron Diffraction (RHEED) consists a compact size electron-gun with mounting via CF1.33″ (ICF34) flange.
  • The compact size e-gun brings easy mount to a vacuum chamber or easy maintenance.
  • Reflection High-Energy Electron Diffraction (RHEED), a reflection high-energy electron diffraction equipment, consists of a CF 1.33″” flange mount and a small size electron gun.
  • The compact electron gun enables easy maintenance and allows parallel operation of other optional devices under high pressure conditions or when observing scanning plane samples of the electron beam.
