Is there a simple method to detect or even measure an electron beam in free air? Preferably without circuitry - however Im sure attaching some electrode to a FETs gate is the only simple method.

...pick up phosphorescence signatures...
In free air (under normal pressure and temp) an electron beam may travel only a few mm (if the energy is in the MeV range, then perhaps 4-5 mm max). The beam will be a mess (cannot be called a beam) because of scattering. After that it will attach to some air molecules and produce negative ions. Detecting free electrons in air will be tricky if not impossible.
the rock/mineral would turn phosphorescent?
...I also think of lightning since it's a flow of electrons. The path is ionized air...
searching for glowing atmospheric gasses would also indicate an electron beam...
