Conclusions
-
1.
When the glasses studied are irradiated by a stream of electrons so that segments are produced as ribbons with a 5∶1 ratio of length to width, the electric field is equivalent to the field from a uniformly charged filament of finite length placed along the symmetry axis of the irradiated segment.

2.
Segments of aluninum phosphate glass, of length about 10 mm, irraidated by a stream of electrons can set up in the surrounding space an inhomogeneous electric field such that the strength is of the order of 103 V·mm−1 at the distribution maximum about one millimeter above the surface.
