Fe55 with 50/50 Ar/CO2, New preamp and new HVB, ADC half-range
Mixed 50/50 at 40 sccm total, moved the source (collimated as usual) across the top of the straw towards the edge....
With the source over the edge of the straw, the count rate halves and the camel disappears.

Overlaying side and edge data, the light coloured plots are with the source above the wire.
