We could try 2.2 Vpp on both x and y, and at the same time add an offset of -0.1 V to y to lower the beam a little. That way we would avoid the void at top and still raster over the “good part” of the target.
<div class="">Similarly, we could increase the offset on x to +0.1 V.</div>

<div class="">Finally, on an unrelated note, we should ask MCC to deliver 4 nA on the FC, not 3.6 or even less.</div>

Yes, we are touching the wall on the top slightly. The void is real, less material there. Shal we reduce the size for the next run?<o:p class=""></o:p></div>

It looks like we are a bit overrastering. I think we should reduce the size a bit. Maybe change Vpp from 2.4 to 2.3 V.<o:p class=""></o:p></div>
