DEVICE FOR ELECTRIC DISCHARGE |
摘要 |
Electric discharge element (1) comprising a cathode (2) which cooperates with an electron duct cavity (10) which is defined by walls (7, 8, 9) of electrically insulating material having a secondary emission coefficient delta , which cavity (10) has an output aperture (11), while electrode means (12) which can be connected to a voltage source ( DELTA V) are provided for applying, in operation, an electric field across a path in the cavity (10) from the cathode (2) to the output aperture (11) so as to enable electron transport through the cavity (10). |
