Flood Gun FS 100
For charge neutralization of positively charged samples like semiconductors or insulators in e.g. XPS/AES or SIMS experiments, OmniVac provides the FS 100 Flood Source, an easy to handle and reliable flood source.
The FS 100 provides a constant flux of low energy electrons which serve for effective charge neutralization in the region of interest.
The PS-FS 100 power supply allows for an easy control of the important working parameters, i.e. electron energy and emission current. If desired, an RS 232 or RS 485 can be implemented for remote control operation of the device.
