The report describes a programme of work in which a previously existing hard-wired logic sequencer for the UK T5 10cm diameter ion thruster was replaced by a sequence generated by an Intel 8080A microprocessor. Details of the new system are given, together with background information relating to sequence requirements that arise from the thrusters electrical power needs. Electrical features of the ion thruster are described where relevant to the switch-on procedure. A second, minor, part of the Report proposes a logical extension to the use of microprocessors in the ion thruster power conditioner context. Such use would realize much more fully the potential of these devices, and would result in a reduction of the mass a volume of the power conditioner and increase its reliability. Author
