KRI KDC75 Source Profile

The ion mill system is equipped with a KRI KDC75 ion source with defocused molybdenum grids and an automatic controller. The source was purchased new on 10/16/2014. Figure 1 is a snippet from the certificate showing the ion current density profile when measured 15 [cm] away from the source. The process parameters for the measurement is shown in the table below.
