Profile: Nonsequitur Technologies Inc specializes in the development, design and manufacture of electron & gas phase ion sources. Our ion gun products are used for a variety of applications. Our products include ion optical columns & electron guns/emitters and surface analysis equipment. The model 1401 ion gun is ideal for use in surface chemistry experiments such as sample preparation and depth profiling with auger and ESCA. It can be used with inert gasses. The controller with power supplies and scan electronics is housed in a single rack mount cabinet. The ion gun can be controlled either from the front panel or through a flexible interface allowing control of beam and focus voltages, ionization current, gas, beam on/off & raster. The raster scan is digitally generated for uniform etch rate.
