Mo-Re metal alloy "stamp" .002" thick.
Molybdenum-Rhenium
Skimming, tried at
222kV @ 20uA then again at 15uA. Same patterns for both, the higher current just gave higher peaks.
Pictures show geometry. Beam comes up from bottom shims through the 1mm gap between the sensor collimator and the target material.
Linear display, 2 versions with appropriate gain to show the peaks of interest.
