Nettet31. jul. 2024 · As a plasma source, by spraying plasma to the space environment, a hollow cathode plasma contactor (HCPC) can establish a current loop with the space plasma. To date, HCPC has been used in the fields of spacecraft surface potential active control [ 1 – 8] and electrodynamic tether technology [ 9 – 14 ]. NettetA test series of hollow cathodes and hollow cathode plasma contactors was initiated as part of the plasma contactor development program. An on-going wear-test of a …

Nettet6. des. 2024 · Deuterium background correction was used; the radiation source consisted of hollow cathode single-element lamps with a current of 4.0 mA. An air/acetylene mixture was used for the determinations. The determinations were performed in the flame mode at the following wavelengths: 357.9 nm for chromium, 232.0 nm for nickel, 324.8 nm for … NettetSpace Station plasma contactors [2] use hollow cathodes to emit electron current, as demanded, to the ambient space plasma at low coupling voltages, thus compensating for spacecraft charging. For all of these applications, long cathode lifetime is critically important. The entitlement, or theoretical maximum, lifetime of NettetUsed in Mission-critical Space Applications Built using the same quality systems that are used for space-qualified microwave cathodes, 3M™ Hollow Cathodes (PDF, 135.48 Kb) are used in mission-critical space applications including ion sources, electric propulsion, plasma contactors and spacecraft neutralization.
