Multi-Mode Thruster with Anode Layer Development Status

Thruster with anode layer (TAL) is the Hall type thruster originally developed at TsNIIMASH in 1960th. Multi-Mode TAL concept means the thruster possibility to operate in wide characteristics range. It fully implements advantages of the two-stage TAL scheme. Two-stage scheme allows flexible regulation in unique operation range for Hall thrusters with anode layer. Based on design D-100 (two-stage) and D-55/TAL- WSF (one-stage) new generation multi-mode thruster was developed and thoroughly researched since 1999. Current R&D status of the thruster presented in the paper.
