WebBeams of electrons can be deflected in magnetic fields (in circles). Electrons are absorbed by metals. Beams of electrons or cathode rays have applications – like televisions and cathode ray oscilloscope (CRO) tubes. Most of these ideas can be demonstrated by either a fine beam tube or a deflection tube. WebThe higher power levels (hundreds of watts) and frequencies (above 8 gigahertz [GHz]) are dominated by electron tubes and the lower levels by solid-state devices. btp firearms twitter
