“…8,9 Owing to such attributes, it has become a crucial development direction of backscattering intelligent attenuation technology. 10,11 Existing plasma generation methods for backscattering attenuation include ultraviolet photoionization, 12 hollow cathode low pressure discharge, 13 coaxial glow discharge, 14 electric barrier discharge (DBD), 15,16 radio frequency discharge, [17][18][19] and low pressure mercury vapor discharge (fluorescent lamps or ultraviolet ARTICLE pubs.aip.org/aip/adv lamps). 20,21 Among them, the low pressure mercury vapor discharge mode has several advantages, such as low power consumption, large plasma quantity, sustained stable maintenance, mature technology, and low price.…”
