Electron Flood Guns

Low cost electron flood guns for charge neutralisation.

The FS 40A1 is a compact, easy to use and reliable electron flood gun for charge neutralisation of insulators or semiconductors in XPS/AES and SIMS applications.

The electron flood gun operates over two energy ranges 0 ...10 and 10 ... 500 eV, is fully software controlled and can also be supplied with custom insertion lengths and shielding materials, e.g. mu-metal, copper. The electron current is continuously variable over the range 0.1 to 500 μA.

Standard insertion depth is 145 mm and recommended working distance is 41 mm. Mounting flange is DN 40CF.
