Ok, so you are blocking the alphas coming from Am241 so they can't excite the target, right?? But doesn't that also block the lower energy xrays we would like to detect coming from the target?
It is a dual gooseneck halogen source.

See pic of normal interfering 2 keV peak (black outline) vs Red Filled=Alpha Blocked. Is that a 2 or 3 light setup? I see 2 sidelights but can tell if there is a toplight. Geo
