Here's the next step, it's a redo of the Source Filter test (which I built
close to but not exactly to your specifications, will clean that up later in
the shop) with the Cu close to the source rather than the sensor side, allowing
the Ti and Al to attenuate the cu characteristic X-Rays that showed up on the
last plot.
More tests tomorrow, this has been real-time, making adjustments per
recommendations.
Great fun
PS in between these trials, the Ba-133 testing was running on another
instrument. Will post that tomorrow. Looks good.
