IBEX components:
LeCroy WaveStation WS2052 arbitrary waveform generator wasn't good enough, used Tabor WaveSeries WW2074
Eventually went for custom amplifiers from APEX, using P898 or PA194 op amps, the latter goes to 450V.

Ion gas pressure O(1e-7) mbar to create O(1e6) ions

Good results in integrable optics test
