Abstract : The purpose of the Coreless Linear Conduction Pump (CLCP) was to evaluate the feasibility of the CLCP as a means of building Thermoelectromagnetic Pumps (TEMPs) that are not, in themselves, temperature limited by the Curie point of ferromagnetic cores or do not limit the temperature capability of the Nuclear Space Power Systems (NSPSs) in which they are used. A TEMP is a single component in which a thermoelectric generator (TEG) and an electromagnetic pump (EMP) are highly integrated. The CLCP concept employs coreless linear magnets rather than circular magnets with or without ferromagnetic cores. Also in the concept, the counter-current, parallel busbars which lie on either side of the pump duct and that constitute a linear magnet carries the integrated field and armature currents to provide the magnetic field at the entrances to the magnet and the pumping section. As the current proceeds down one busbar a portion of it becomes armature current by crossing the pump duct to the other busbar while the remaining field current continues down the busbar. The partitioning of the currents happens all along the busbars and duct until it is all consumed.
